Understanding Acne Scars

Not all acne scars are created equal. To choose the best treatment, it’s essential to understand the types of scars acne can leave behind:

Ice Pick Scars are deep, narrow indentations extending into the dermis, almost like tiny punch-hole marks. Ice pick scars are common (about 60–70% of atrophic scars)​.

They can be the toughest to treat because of how deep and narrow they are – often requiring targeted treatments like chemical reconstruction (CROSS) or punch excision rather than fillers.

Boxcar Scars: Boxcar scars are wider depressions with defined edges (like someone pressed a fingernail into clay). They often occur on the temples or cheeks.

Because they have flatter bottoms, boxcar scars can respond well to dermal fillers, which lift the depressed area, especially if the scars are shallow to medium depth.

Rolling Scars: These scars cause broad depressions with sloping edges, giving the skin an undulating or “wavy” texture. Rolling scars result from bands of scar tissue pulling the skin down.

Fillers are particularly effective for rolling scars – by releasing the tethered bands (often via submission) and filling the volume loss, we can achieve a much smoother surface.

Hypertrophic Scars & Keloids: Unlike the above “indented” scars (called atrophic scars), hypertrophic scars and keloids are raised, firm scars caused by excess collagen. These usually appear on the chest, back, jawline, or shoulders.

Rellenos dérmicos are not used for raised scars – in fact, raised scars are often treated with corticosteroid injections, laser therapy, or silicone since the goal is to flatten them, not fill them. This article focuses on the indented, atrophic acne scars that fillers can improve.

Why do acne scars form?

In severe acne, inflammation damages collagen deep in the skin. When the breakout heals, there isn’t enough collagen to restore the skin’s smoothness, leading to a depression or “pit.”

Our bodies try to repair acne wounds, but an atrophic scar remains if collagen is laid down unevenly or if too much tissue is destroyed. These scars are areas of volume loss or tethering beneath the skin.

This is why dermal fillers, which restore lost volume, are a logical solution for certain acne scars – they replace the missing structure under the scar.

Conventional Treatments vs. Fillers

Before dermal fillers became popular for acne scars, other treatments were (and still are) commonly used to address these stubborn marks. Each approach has strengths, and often a combination yields the best result.

Here’s a quick overview of popular acne scar treatments and how they compare:

Rejuvenecimiento con láser: Laser treatments (like fractional CO₂ or erbium lasers) create controlled micro-injuries in the skin, triggering new collagen production and resurfacing the top layers. Lasers can significantly improve texture and pigmentation.

They are especially effective for shallow boxcar scars and widespread unevenness. However, they may require multiple sessions and a week or more of downtime (redness, peeling).

Some patients with deeper scars find that lasers alone aren’t enough to fully “fill in” depressions – that’s where fillers or subcision come in. Evidence suggests combining a laser with fillers or other modalities yields better results than using a laser alone​.

Are fillers or lasers better for acne scars?

It’s not an either/or – in many cases, we use both. Lasers improve surface texture and overall skin quality, while fillers restore volume under deep scars.

Chemical Peels: Chemical peels (like TCA or glycolic acid peels) remove the top skin layers to improve skin texture and tone. A strong focal TCA peel (the CROSS technique) can target ice-pick scars by inducing collagen in the scar.

Peels are excellent for treating post-acne discoloration and very superficial scars. They are less effective for deep pitted scars – a peel can soften the edges of boxcar scars but won’t raise a deep crater.

We often incorporate peels in an acne scar program for overall complexion improvement, but they do not “fill” an indent.

Microne on their ownedling & RF Microneedling: Regular microneedling uses tiny needles to stimulate collagen in the skin. Newer techniques combine microneedling with radiofrequency (RF) energy delivered into the skin for a more substantial effect.

These treatments are minimally invasive with little downtime (just a day or two of Redness) and can gradually improve rolling or shallow scars with repeated sessions. Microneedling is safe for all skin tones.

It can improve overall texture, but deep pits might persist if the volume is missing underneath. Sometimes, we perform microneedling with platelet-rich plasma (PRP) or even alongside filler injections in alternating sessions for a one-two punch.

Subcision: Subcision is a minor surgical procedure that is beneficial for rolling scars. A needle or tiny blade is inserted under the scar to break the fibrous bands, tethering the skin down manually.

This allows the scar to lift and induces collagen as the area heals. Subcision can produce significant improvement, especially when combined with other treatments.

Often, we perform subcision first to release a scar, then immediately inject a filler into the space to keep it elevated – think of it as freeing and propping it up. This combination can yield excellent results, and studies back this up: for example, the research found that adding filler to subcision significantly improved outcomes compared to subcision alone​.

If you have rolling scars, subcision with fillers is frequently the gold standard approach.

Topical Treatments: Prescription retinoids, silicone gels, and other topicals have limited impact on true indented scars. They can help prevent scars by healing acne faster and slightly improving texture over many months, but they won’t remove established scars.

Don’t be fooled by over-the-counter “scar creams” – atrophic acne scars typically need procedural treatment for real improvement.

However, topicals are great for improving post-acne pigmentation and overall skin health, so we often include them as part of a comprehensive plan (for example, using retinol to encourage cell turnover while doing in-office treatments).

What Are Dermal Fillers?

Rellenos dérmicos are injectable gels that restore lost volume, contour the face, and fill in wrinkles or depressions. They are a cornerstone of cosmetic medicine for facial rejuvenation (think rellenos labiales or cheek fillers).

When it comes to acne scars, the same concept applies: fillers add volume beneath indented scars, lifting them to be flush with the surrounding skin. Beyond the immediate fill, many modern fillers stimulate your body’s collagen production in the treated areas, leading to long-term improvement even after the filler is absorbed.

Most fillers are made of biocompatible substances that are eventually broken down by the body. They are injected using a fine needle or cannula after the skin is numbed.

The procedure is quick (often 30 minutes or less) with minimal discomfort, and results are immediately visible. This makes filler an attractive option for those who want to see fast improvement in their acne scars without surgery or significant downtime.

There are different categories of dermal fillers, including:

Hyaluronic Acid (HA) Fillers: The most popular type is made of a gel that contains hyaluronic acid – a substance naturally found in our skin that binds water and adds plumpness. Examples include Restylane and JuvédermJuvéderm.

HA fillers are temporary, typically lasting 6–12 months for acne scars, and can be dissolved with an enzyme if needed (which gives peace of mind – it’s a very safe and versatile filler type)​. These are commonly used for acne scars due to their safety profile.

Collagen-Stimulating Fillers: Also called biostimulatory fillers, these include substances like poly-L-lactic acid (PLLA) (brand name Sculptra), calcium hydroxyapatite (CaHA, brand name Radiesse), and polycaprolactone (PCL, brand name Ellansé).

They work by causing controlled inflammation that triggers your fibroblasts to produce new collagen over time​. They also provide some immediate volume, but their main effect is gradual.

These can last longer (1–2 years or more) since they change the skin’s foundation.

PMMA (Polymethylmethacrylate) Fillers: The primary example is Bellafill (formerly known as Artefill), which consists of 20% PMMA microspheres suspended in 80% bovine collagen gel​. The collagen provides initial volume, and the PMMA microspheres remain permanently in the skin, which induces collagen around them.

Bellafill is the only FDA-approved dermal filler specifically for treating acne scars (approved in 2015 for certain types of atrophic facial scars on the cheeks). It is considered a semi-permanent or long-lasting filler – results can last 5 years or more, and the PMMA particles stay indefinitely​.

Autologous Fat Transfer: While not a manufactured “filler” product, your fat can be used as a natural filler. Fat is harvested via mini liposucción from one area (like the thigh or abdomen) and then processed and injected into scarred areas to fill them.

Fat grafting has the advantage of using your body’s tissue and can improve skin quality due to stem cells in fat. Studies show fat grafting can effectively treat acne scars with high satisfaction​.

However, the procedure is more involved (requiring a minor surgical process to obtain fat), and some of the injected fat may not survive, potentially requiring multiple sessions.

In our practice, we use commercial fillers for acne scars more due to their predictability, but fat transfer is an option for significant volume needs or specific cases.

How Dermal Fillers Treat Acne Scars

Dermal fillers treat acne scars in two primary ways:

Physical Lifting of the Scar: When a filler is injected under a depressed scar, it adds volume and pushes the base of the scar upward. Imagine a deflated balloon (the scar) being re-inflated – the goal is to raise the depth of the scar to the level of the normal surrounding skin.

This makes the scar far less noticeable, often nearly invisible in good light. In technical terms, we are recontouring the dermis from beneath.

For example, if you have a sunken scar on the cheek, a few drops of filler placed precisely under it can instantly make that little pit disappear. This physical fill is incredibly impactful for rolling scars and broad, shallow boxcars.

Collagen Stimulation: Beyond the immediate fill effect, many fillers stimulate your body to produce new collagen in the treated areas. This is true for biostimulatory fillers like Sculptra, Radiesse, Bellafill, and even to a degree for hyaluronic acid fillers (HA fillers can trigger collagen production through stretch of fibroblasts and the inflammation of injection)​.

The new collagen can improve the scar’s appearance and prolong the results even after the filler material is absorbed. The filler acts as a scaffold or catalyst for your skin to heal with more collagen.

This is wonderful for acne scars because it means the improvement can last. For instance, studies have shown that injecting HA filler or PLLA into acne scars not only immediately improves them but also leads to scar remodeling over months.

Fillers can treat most types of atrophic acne scars, but we always tailor the approach:

• For rolling scars and broad depressions: Fillers are typically very effective, often combined with subcision. By releasing the tethers and filling volume, we can see dramatic smoothing.
• For boxcar scars: If shallow, fillers can fill them nicely. If they have very sharp edges or are deep, we may do a bit of laser or even a minor punch excision first, then fill the residual depression.
• For ice pick scars: Fillers are generally not the first choice because these scars are like tiny deep ice picks – filler may not stay put or effectively lift such a narrow pit. We usually treat ice picks with other methods (like TCA CROSS or punch excision) and maybe use a touch of filler after if there’s any residual depression.

For more considerable area atrophy (for example, some people get an indented “scar” from cystic acne that’s broad), A filler can be threaded under the area to plump it back up.

Types of Dermal Fillers for Acne Scars

Choosing the appropriate filler is critical for a successful acne scar treatment. Different fillers have different properties – some are softer, some firmer, some last months, others years.

We select the filler (or combination of fillers) based on the scar characteristics, treatment goals, and patient preferences (for example, temporary vs long-lasting). Below is a comparison of filler types commonly used for acne scars:

Hyaluronic Acid (HA): Smooth gel, great for first-time treatment. Adds immediate volume and is adjustable (can be dissolved if needed). Low risk and minimal downtime. It is ideal for shallow to medium-depth scars.

PMMA (Polymethylmethacrylate): A collagen stimulator injected as a solution that triggers collagen over months. Results appear gradually (after 2–3 sessions, a few weeks apart).

Great for improving overall atrophic areas and multiple scars at once. Not for very localized “one scar” fixes, but excellent for a general filling of sunken areas (e.g., temples or cheeks with diffuse scarring).

CaHA (Calcium Hydroxyapatite): Thick, gel-like filler with microscopic calcium particles. It provides an immediate lift and stimulates collagen.

It can be diluted in scars or full-strength for deeper tissue. It is helpful for some broader scars but less commonly used than HA or Bellafill for facial acne scars.

Often chosen for deeper dermal filling needs.

Autologous Fat: Uses your fat tissue as a natural filler. It can permanently improve volume if the fat “takes.”

It is often combined with PRP or stem cell concentrates in acne scars for better retention​. Suitable for large depressed areas (e.g., significant cheek atrophy from old cysts). More invasive; results vary.

Fillers vs. Laser: Which Is Better?

One of the most frequent questions is, “Should I do laser or fillers for my acne scars? Which is better?”

The honest answer is that they do different things; many patients benefit from both. However, one approach might be prioritized depending on your scars and life circumstances.

Let’s compare key points:

Effectiveness: Rellenos dérmicos excel at treating depressed scars by lifting them. Laser resurfacing excels at improving surface texture, pigment, and shallow irregularities. If your main issue is deep pitting, fillers will likely make a more noticeable immediate difference.

If your main issue is delicate textural scarring and Redness, a láser fraccional might improve more uniformly. A 2016 evidence review concluded there was moderate evidence supporting fillers for acne scars, while evidence for fractional lasers was considered limited or variable.​

This doesn’t mean lasers don’t work – they do, and can achieve ~50% scar improvement in many cases – but in clinical trials, filler injections produced a high rate of scar improvement as well (with one RCT showing a clear advantage of filler over placebo)​

In practice, we often see the combination of subcision + filler + laser yield the best overall improvement, tackling the scars from multiple angles.

Longevity: Laser treatments cause a permanent change in your skin (new collagen, scar remodeling). The improvements from a successful laser series can be long-lasting, but remember that aging and sun exposure can make scars look worse again if they are not maintained.

Fillers have a finite lifespan in the skin (months to years). For example, an HA filler may last ~1 year in scars, so you might need a touch-up annually to maintain full correction.

Bellafill lasts 5+ years, so it’s closer to the permanence of a laser result. If someone wants a “one and done” long-term solution, a procedure like Bellafill or a series of aggressive laser sessions could both be considered – Bellafill physically remains, and lasers permanently alter scars.

Both can be long-lasting; one big difference is that HA fillers can be reversed if you don’t like the outcome, whereas laser changes (or Bellafill) cannot be easily undone. However, adverse outcomes are rare with experienced providers and proper patient selection.

Downtime & Side Effects: Filler injections have minimal downtime. You might have some pinpoint bruises or swelling for a few days.

Lasers (especially ablative lasers like CO₂) have more significant downtime – expect Redness, peeling, and needing to avoid the sun for a period. Non-ablative lasers have less downtime but also more subtle results.

Side effect profiles differ too: fillers risk bruising, swelling, rare infections, or infrequent vascular complications (which is why you need a skilled injector). Lasers risk post-inflammatory hyperpigmentation (especially in darker skin tones), prolonged Redness, or rarely scarring if not done correctly.

In general, fillers have lower downtime; when done by an expert, they are relatively safe. Lasers are safe in expert hands but require more aftercare; starting with fillers can be attractive for busy professionals who can’t take time off for a laser recovery.

Treatment Areas: Some scars (like those on the temples or cheeks) respond well to either approach. Certain areas, like the nose, are tricky to laser aggressively (risk of pigment issues) but could be injected carefully with filler if needed.

Conversely, broad, rough skin texture across the entire face might be better addressed by full-face laser, possibly combined with spot filler for any deep pits. At our med spa, we evaluate where each scar is and decide the best tool.

Sometimes, during a filler session, we’ll tell a client: “These three scars filled nicely with filler, but that tiny ice-pick scar would do better with a touch of TCA peel.” It’s genuinely about customizing each scar, even within the same face.

Patient Comfort: Some people are needle-averse, others fear lasers. Fillers involve needles (with numbing, most patients tolerate it well).

Lasers involve light and heat (we also use numbing and sometimes cooling or PRO-NOX™ for comfort). If a patient doesn’t want injections, we may lean towards laser first – and vice versa.

That said, most clients with acne scars are willing to do whatever will give the best result, especially once they understand the process and trust us.

So, which is better?

If pressed, dermal fillers are the fastest way to see a significant improvement in indented acne scars, and lasers are an excellent complementary treatment to refine and enhance those results. For instance, we might do subcision and fillers first to get the structural improvement (so scars are lifted), and a couple of months later, do a fractional laser to polish the skin’s texture and stimulate additional collagen.

This layered approach often yields dramatic transformations, far superior to either treatment alone. In support, one study showed that combining modalities (like microneedling + filler) significantly improved scars versus a single modality​.

However, if someone has excellent shallow scars and is younger, they might do laser or microneedling and not require filler. Or suppose someone cannot have a laser (for example, a very dark skin type unsuitable for aggressive laser).

In that case, filler becomes even more valuable as a primary treatment since it’s color-blind (fillers don’t affect pigment or the epidermis).

In summary, fillers and lasers are not mutually exclusive but best considered complementary tools. During your consultation at Beverly Hills Wellness Center & Med Spa, we will explain the pros and cons as they apply to your skin.

Many patients ultimately choose a combined plan. Our goal is maximum safe improvement. If that means doing a filler first and a laser later, or vice versa, we’ll map that out for you.

We can offer comprehensive care for acne scars by having all these technologies in-house.

For example, our acne scar correction program might involve:

Step 1 – do subcision and filler this month;

Step 2 – do a light laser peel or microneedling next month;

Step 3 – evaluate and add more filler to any stubborn scar if needed.

This multi-step approach ensures we methodically address each aspect of scarring.

Now, let’s walk through what it’s like to get dermal filler treatment for acne scars at our med spa – from consultation to aftercare.

Treatment Process at Our Med Spa

At Beverly Hills Wellness Center & Med Spa, we pride ourselves on a personalized, comfortable experience. Here’s what you can expect when you come to us for acne scar filler treatment:

1. Comprehensive Consultation: We begin with a thorough consultation and skin analysis. One of our experienced providers will examine your scars in detail, possibly using various lighting and even skin imaging.

We’ll discuss your skin history. Feel free to share what bothers you most about your scars – are there certain spots, what is the overall texture, etc.?

We’ll also review your medical history to ensure you’re a good candidate.

Together, we’ll set realistic expectations – for instance, some deep scars might improve significantly but not 100% vanish; we aim for significant improvement, not necessarily “plastic perfect” skin, although some patients come pretty close to scar-free after treatments.

2. Customized Treatment Plan: We’ll recommend a plan based on your scar assessment. If dermal fillers are indicated, we’ll decide which type and how much.

Often, we quantify in syringes for HA fillers or vials for Sculptra. For example, we plan to use one syringe of Restylane Lyft for subcision and filling today and possibly a second syringe at a follow-up visit if needed.

If Bellafill is chosen, and you haven’t had a skin test yet, we’ll administer a quick allergy test (a tiny injection in your forearm) and wait 4 weeks for results before proceeding.

In the meantime, we could do other prep treatments like a peel or start you on skincare. The plan may include adjuncts like “Laser after 4 weeks” or “Microneedling for remaining shallow scars.”

We’ll prioritize your main concerns first – for example, if you have an event coming up, we might do fillers now for instant improvement and save lasers for later.

3. Pre-Treatment Prep: On the day of filler treatment, you’ll be comfortably seated in our procedure room. We’ll cleanse your face thoroughly.

We typically take clinical photos for your chart (so we can track progress). Then, we apply a potent topical anesthetic (numbing cream) on the areas to be treated and let it sit for ~20–30 minutes.

We want you to be as comfortable as possible. If you’re very anxious about needles, let us know – we also have Pro-NOX™ (a safe self-administered nitrous oxide gas that takes the edge off anxiety and pain, much like laughing gas at the dentist).

Most patients tolerate acne scar injections with just the cream because we use wonderful needles and gentle techniques. We might also give you an ice pack to cool the skin and minimize potential bruising.

4. The Injection Procedure: Once you’re numb, the provider will remove the numbing cream and thoroughly sanitize the skin with an antiseptic. Then, using either a needle or a blunt cannula (or both), they will strategically inject the filler beneath each targeted scar or area.

For submission, a needle (such as a Nokor needle or even the filler needle) is inserted under the scar and moved in a fanning motion to break adhesions. You might hear or feel little “pops” as scar tissue releases – this is normal.

Immediately after freeing a scar, the filler is injected to occupy the space. We often work systematically across the face, focusing on one region at a time.

We check in on you; you may feel pressure, an occasional mild sting, or tugging, but it shouldn’t be painful. The number of injection points can vary – a single scar might need 1–3 insertion points around it to release and fill adequately.

A session can take anywhere from 15 minutes for a few scars to 45 minutes for extensive scarring.

We strive for artistry – the provider will continuously assess the skin from different angles, perhaps using a penlight to ensure the previously shadowed dents now have light reflection (a sign of a smoother surface). You might be handed a mirror to give feedback as well.

We truly work with you, as you know your scars best under your usual home lighting; sometimes, we ask if there are certain scars you notice most so we can be sure to address those thoroughly.

5. Post-Treatment: After injections, we’ll gently clean your face. You will see some immediate improvement – don’t be surprised if you get a bit emotional (we’ve had patients tear up with joy seeing scars fill in that bothered them for years).

During the submission, there will also be temporary swelling from the filler and mechanical action. So your skin might look a little puffy or have minor lumps – we assure you this is normal and will subside in days.

We apply ice to minimize swelling and may put arnica gel on to help prevent bruises. Tiny injection marks or pinpricks are covered with antibiotic ointment.

We’ll review aftercare instructions: for 24-48 hours, avoid strenuous exercise, saunas, or anything that increases blood flow to the face (to reduce bruising risk). Don’t massage or manipulate the treated areas unless instructed – we sometimes mold the filler during injection, but it’s best to let it settle after we’re done.

You can gently wash your face later that day and apply makeup the next day if needed. We suggest you sleep with your head slightly elevated the first night and not put direct pressure on treated areas (so skip the face-down sleep posture).

Most patients have mild soreness – Tylenol is usually enough if you feel any discomfort (avoid NSAIDs like ibuprofen for a day or two if possible since they can increase bruising).

6. Follow-Up: We’ll see you back about 2 weeks later to evaluate the results once everything has settled. At that point, any swelling is gone, and we can honestly assess how much improvement we have achieved and whether any scars need more filler.

It’s often better to slightly under-fill initially and add more later than to overfill. So, we scheduled this follow-up with the expectation that we might do a bit more injection if needed (ideally, we budget filler accordingly from the start).

If all looks great, we can proceed to other planned treatments like laser or microneedling in subsequent visits. And, of course, we’ll take after photos to compare with your before – this is one of the most satisfying parts!

From start to finish, our goal is to make your acne scar treatment journey smooth (no pun intended) and rewarding. We emphasize patient education and comfort at every step.

You are not just a number to us – we know how personal this is, and we genuinely share in your excitement as your scars fade away.

Seguridad y efectos secundarios

A common concern is, “What are the side effects of filler for acne scars? Is it safe?” The great news is that dermal filler treatments, when performed by trained medical professionals, are generally very safe with a low incidence of serious side effects.

At our spa médico, patient safety is our top priority – we use FDA-approved products and aseptic techniques and have extensive filler injection experience.

Typical Side Effects: The most common side effects of acne scar filler treatment are minor and temporary. These include:

Redness and Swelling: It’s normal for injection sites to be red and swollen for 1–3 days. If we did extensive subcision, you might have generalized puffiness in treated areas.

This is usually mild and can be covered with makeup the next day. Cold compresses help, as does sleeping elevated the first night.

Bruising: Anytime a needle goes under the skin, there’s a chance of hitting a tiny blood vessel. Minor bruises can occur, especially on the cheeks or under the eye area where the skin is thin.

Bruises from filler are typically minor and resolve in about a week. We minimize this risk by using microcannulas for some injections (which tends to cause less bruising) and by recommending you avoid blood-thinning meds or supplements pre-treatment if possible.

We offer complimentary laser bruise therapy to clear it faster if you get a noticeable bruise. Arnica supplements or topical arnica can also speed up bruise resolution.

Tenderness or Soreness: The treated areas may feel a bit tender for a few days, similar to how a bruise feels. This is usually very mild.

If a submission was made, you might feel an “internal” soreness (like a mild ache under the skin) – this is the healing of released tissue. Over-the-counter acetaminophen is usually all that’s needed, if anything.

Small Lumps or Irregularities: In the first week, you might feel tiny lumps where the filler was placed. Don’t panic – this is often due to swelling or excess filler that hasn’t yet been integrated.

We usually advise gentle massage of any palpable lump after about 48 hours (once the initial swelling is down) – our team will instruct you on this if needed.

With HA fillers, if a lump persists after a couple of weeks, it can be adjusted or dissolved easily, but that’s rarely necessary. With Bellafill or Sculptra, lumps are uncommon when proper technique is used (e.g., Sculptra must be thoroughly diluted and evenly distributed to avoid nodules).

In the Bellafill 5-year study for acne scars, only about 1.4% of cases developed mild nodules or similar reactions.​

Itching or Redness at injection sites as they heal, especially with HA fillers or if you have sensitive skin. This is temporary and can be managed with a gentle hydrocortisone cream if needed (though we usually just let it be, as it resolves quickly).

Less Common/Rare Side Effects

Infection: We take great care with the antiseptic technique. Infection from filler injections is exceedingly rare.

You’ll be instructed to keep the area clean and not introduce bacteria (for example, avoid touching the face with unwashed hands immediately after). If fection occurevers occurs (by increasing Redness, Redness, pain, possibly pus), it can be treated with antibiotics.

We have not seen this in practice for acne scar patients thus far.

Allergic Reaction: Modern fillers are made to be biocompatible. HA fillers are made of a substance natural to the body and are non-animal derived, so true allergy is very rare.​

There is a slight chance of being allergic to components like lidocaine (in many fillers) – let us know if you have any drug allergies so we can use a filler without lidocaine or do a patch test.

Bellafill, because it contains bovine collagen, requires a skin allergy test (we do this for your safety). In the original trials, a few patients (under 3%) showed sensitivity to the test and thus did not proceed with Bellafill.

We only treat you with it if the test is negative. Sculptra and Radiesse have extremely low allergy rates as well.

An allergic reaction might cause prolonged Redness or swelling; steroids or antihistamines can manage it. Again, this is relatively uncommon.

Granulomas or Nodules: This is a concern, particularly with biostimulatory fillers. A granuloma is a firm lump that can occur if the sistema inmunitario and the filler walls strongly react.

Studies report low rates of granulomas with newer fillers. For example, PMMA filler historically had some nodule formation issues with older products, but Bellafill’s newer formulation significantly reduced that risk (around 1–2% or less, and it is typically treatable)​.

Sculptra granulomas were more common in the early 2000s when injection techniques were still being refined; now, with proper dilution and injection depth, they are rare (estimated <1% in experienced hands).

If a patient does develop a persistent nodule, treatments include injections of corticosteroid or small amounts of 5-FU, or in the case of HA, just dissolving it with hyaluronidase. We have the tools and expertise to manage such issues should they arise.

Vascular Occlusion: This is a sporadic but serious risk with any filler injection – if the filler accidentally enters a blood vessel and blocks blood flow. It can lead to skin tissue loss if not quickly addressed.

Our team is highly trained to avoid this (knowing anatomy, using cannulas near dangerous zones, aspirating needles when needed, injecting slowly, etc.).

In an acne scar context, we often work superficially and in scar tissue, which lowers this risk compared to deep filler injections for, say nose augmentation. We also have protocols in place.

We have hyaluronidase on hand for HA fillers to dissolve any filler immediately if an occlusion is suspected. We also closely monitor the tissue during injection.

Thankfully, we’ve never encountered this complication in our practice, and it’s doubtful when treating acne scars specifically, but we stay prepared and vigilant regardless.

Overall, dermal fillers have an excellent safety record. A recent review in 2023 looking at multiple acne scar filler studies noted that no serious adverse events were reported, and side effects were typically mild and temporary (Redness, swelling, bumps resolving in days)​.

Another systematic review (2025) commented that fillers were well-tolerated by patients across studies, with only minimal, reversible adverse events reported.

Our approach to safety: We thoroughly screen patients, use sterile techniques, and never cut corners. We also inform and empower you – we’ll tell you what to watch for (e.g., what normal vs. abnormal healing looks like) and make ourselves available if you have any questions during recovery.

Following up as directed is essential to ensure everything is on track. If you have any concerns after treatment, we encourage you to call – even if it’s just for reassurance.

In essence, the side effects of filler for acne scars are manageable and temporary in nearly all cases, and the risk of serious complications is very low in skilled hands. We want you to feel comfortable and confident in your results and the process. We take your trust seriously.

Results and Longevity

Seeing the results is one of the most exciting parts of acne scar treatment. Patients often notice improvement immediately with dermal fillers, but peak results and how long they last can vary depending on the filler used and individual factors.

When will I see the results?

- Immediately: You’ll likely see a significant change after the procedure. Those deep pits will be shallower or gone, and the rolling areas will look flatter.

Remember, there is initial swelling, sometimes making it look like the scars are over-corrected (slightly puffy). This usually subsides within days, and the actual result becomes apparent.

If anything, scars might dip a bit more after swelling resolves, which is expected; we often account for that by slightly over-correction during injection (especially with subcision, as some re-depression can occur when healing).

- 1–2 Weeks: By the two-week mark, swelling, and minor bruising are gone, and the filler has integrated with your tissue. Suppose we used a collagen-stimulating filler (like Sculptra or Bellafill).

In that case, you wouldn’t see the full collagen effect yet, but the immediate volume effect of Bellafill’s collagen or initial Sculptra edema gives you a preview.

At this stage, we evaluate if you need a touch-up. Many patients are already thrilled by this point, noticing that certain scars don’t catch the light or shadow like before. Makeup goes smoother, and even without makeup, you might feel more confident in how your skin looks.

- 6–12 Weeks: The collagen regeneration starts if you have Sculptra or another bio stimulator. You’ll notice continued improvement even though you haven’t had a recent treatment – scars may further fade as your collagen fills them in.

HA filler patients’ results at 6 weeks are typically the same as at 2 weeks (once the swelling is resolved). If we combined treatments (like did a laser a month after filler), then by 6–12 weeks, you see the cumulative benefits: smoother texture from the laser plus volume fill from the filler.

This is often the “wow” point where patients say their skin hasn’t looked this good in years.

How long do dermal fillers for scars last?

The duration of results depends on the type of filler:

- Hyaluronic Acid Fillers are temporary, gradually dissolving as the body metabolizes the HA. In acne scars, HA fillers tend to last on the longer side of their typical range.

This is because fillers can persist a bit longer in scar tissue (which has less blood flow than lips). Generally, HA filler results last around 9–12 months for acne scars.

Some patients get 18 months of improvement, especially after multiple sessions (since repeat treatments can have a cumulative effect). However, to be conservative, we tell patients to expect about a year from an HA filler and then likely need a touch-up. Suppose you do nothing after the filler entirely wears off.

In that case, the scars may gradually reappear to some degree (though often, they never go back to quite as bad as before because there’s some residual collagen or scar remodeling). Many patients come annually for a minor refill to keep scars at bay – akin to maintenance.

Remember, HA fillers’ longevity also depends on the product – thicker, more cross-linked HAs like JuvédermJuvéderm Ultra Plus or Restylane Lyft may last longer than softer ones like Belotero. We choose appropriately for scars (usually a sturdier HA for more lift).

- Bellafill (PMMA): This is considered long-term. The bovine collagen in Bellafill gives an immediate fix but is absorbed in 1–3 months.

By then, your body’s collagen has been laid down around the PMMA microspheres, which remain permanently. Clinical studies showed results at 12 months were maintained or improved at 5 years for acne scars.

Practically, we consider Bellafill a permanent correction. However, aging can cause changes around the treated scars (for instance, if you lose a lot of weight or volume in your face years later, even those areas might shallow out a bit).

In our experience, once an area is treated adequately with Bellafill, it tends to stay scar-free for many years. We still like to follow up periodically; if a new scar forms (from a late acne breakout) or an untreated scar bothers you, we can always treat those.

But the ones we filled should remain improved. It’s worth noting that Bellafill often requires two sessions for optimal results (we might use a certain number of syringes first, then have you back 2-3 months later to add more if needed after initial collagen builds, akin to “layering”).

This staged approach ensures longevity and smooth correction.

Sculptra (PLLA): Sculptra’s collagen stimulation can last 2 years or more. Studies on Sculptra for cosmetic use show that improvements can last at least 24 months after the entire treatment course.​

For acne scars, after a series (say 2-3 sessions), we’ve seen patients maintain better skin for 2+ years. Eventually, as PLLA particles dissipate and collagen ages, touch-ups might be needed (some do a single maintenance vial per year after the initial series).

The nice part is the collagen it induced doesn’t just vanish overnight – there’s a gradual diminishment. So you won’t wake up one day and see all your scars back; you might notice slowly, over time, some depression trying to return, at which point you come in for a booster.

Other Fillers (CaHA): Radiesse lasts about 12-18 months, sometimes a bit less in areas of lots of movement. In scars, if used, expect around a year of results.

Fat transfer, if successful, can be permanent, but often, some of the fat resorbs – usually what remains at 6 months is considered lasting. With fat, you might retain 50% of the initial volume long-term, meaning some of the improvement remains indefinitely, but you might need multiple fat grafts to get a full-lasting correction.

Fat’s longevity also depends on weight stability.

Combination Impact: One interesting thing is that doing other treatments can prolong the apparent results of fillers. For example, we do laser or microneedling after filler, which is when new collagen can further support the area, so even if the filler fades, the scar doesn’t fully relapse.

Our integrated approach often leads to a situation where your scars keep improving or staying better, and we gradually lengthen the interval between interventions.

Patients often ask: “Are indented acne scars permanent? Will they come back after filler?”

Indented scars are permanent if untreated, but after treatment, we have essentially “fixed” the scar to a degree. A particular scar that’s been broken up and filled is permanently improved – it will never be as nasty as it once was.

That said, because some fillers aren’t permanent, there could be some relapse over time, but it’s usually easier to maintain once initial improvements have been made.

Realistic expectations for longevity: We tell our acne scar clients to think of it like improving a road with potholes. We filled the potholes (scars) – and now the road is smooth.

Over time, with wear and tear, a few minor dips might form again – so we patch those up (maintenance). Eventually, the road will stay smooth, primarily with occasional upkeep.

Similarly, after several treatments, many of your scars may be gone for good, and only minor touch-ups are needed infrequently.

To maximize how long your results last, we advise:

Follow a good skincare routine with sunscreen and perhaps retinoids – UV protection prevents collagen breakdown (including the collagen we worked so hard to build in those scars). Sun damage can make scars worse, so SPF is your scars’ best friend.

Keep acne under control – new cystic acne can form new scars or pigment. If you break out again, see us or a dermatologist to manage it promptly.

We often continue acne topical or oral medications for patients prone to breakouts even as we treat scars.

Stay healthy and avoid smoking – smoking, for instance, degrades collagen and can shorten filler longevity.

Do maintenance treatments as recommended. If we schedule you for a follow-up filler in 9 months, that doesn’t mean your scars will fully return by then; it’s just keeping the results optimal.

Some patients do a yearly minor filler touch-up or a laser session to stimulate that collagen.

In summary, dermal fillers offer immediate and long-term improvement for acne scars. HA fillers give you an instant fix that you can enjoy for around a year (and easily extend with touch-ups).

Long-acting fillers like Bellafill or Sculptra give you sustained correction for years in exchange for more upfront planning or sessions. Notably, after filler treatments, the vast majority of patients find their scars are dramatically less visible, and they feel much more confident.

Even if a hint of a scar remains, it’s usually so subtle that it no longer bothers them like it did before. Our goal is to reach that point where you feel good about your skin every time you look in the mirror – and maintain that feeling for the long haul.

Next, let’s address the practical aspect on everyone’s mind: cost. How much will this investment in smoother skin cost, and is it worth it?

Cost of Acne Scar Filler Treatments

Investing in your skin can be one of the best investments you make in yourself. However, we understand cost is a significant factor in deciding on treatment.

How much do fillers for acne scars cost? The cost can vary depending on the extent of scarring, the type of filler used, and how many sessions are needed.

At Beverly Hills Wellness Center & Med Spa, we strive to deliver value – maximizing results in as few sessions as necessary – and we’re transparent about precios upfront so you can plan accordingly.

Here are some general guidelines and considerations regarding cost:

By Syringe or Per Session: Dermal fillers are typically priced per syringe (for HA or Bellafill) or per vial (for Sculptra). The price per syringe can range widely depending on the filler brand and the region.

In West Palm Beach, hyaluronic acid fillers average around $600–$800 per syringe, while Bellafill often costs around $800–$1000 per syringe (it’s a specialized product with lasting results). These are ballpark figures – for instance, a smaller syringe (0.5ml) might cost less, and there are often package deals if multiple syringes are purchased.

According to national statistics, the 2019 average cost for one syringe was about $652 for HA fillers and $855 for Bellafill​. Our pricing is in line with these averages, and we’ll quote you specifically during consultation based on current rates and any promotions.

How Many Syringes Needed: The number of syringes depends on how many scars and the severity. Some patients with just a few scars may only need one syringe of filler.

Others with widespread scarring might use 2–4 syringes over several sessions. We might start with 1–2 and see how much improvement we get, then add more if needed.

For example, if you have moderate rolling scars on both cheeks, we might use one syringe per cheek. If using Sculptra, those are typically sold per vial, and you might need two vials per session and two sessions (for a total of 4 vials spread out).

Each Sculptra vial might be about $800–$900. So, costs can add up for more extensive treatments, but remember the results and longevity.

Subcision Add-On: If we’re doing it together, we usually include subcision as part of the filler procedure – you’re mainly paying for the filler product and the service time. We don’t typically charge separately for a simple subcision when done in conjunction with filler.

If someone undergoes subcision alone (without filler) as a separate procedure, there might be a fee (perhaps a few hundred dollars, depending on time/area). But we often combine it, so it’s rolled into the overall treatment cost.

Combining Treatments: If you’re also doing laser or microneedling, those have their costs. For instance, a fractional laser session can range from $500 to $1500, depending on the device and area.

Microneedling with PRP might be around $300 to $600 per session. We may offer package pricing if you commit to a series (e.g., a package of 3 microneedling sessions at a discounted rate).

Sometimes, med spas offer a comprehensive scar package (e.g., subcision + filler + 2 microneedling for X amount). We’ll explore options that fit your budget and your skin needs.

Maintenance Costs: If you choose a temporary filler, factor in that you might repeat it in a year or so. If each yearly maintenance is one syringe at $650, that’s manageable for many as a long-term plan.

If you choose Bellafill, you pay more upfront (since you may use multiple syringes at ~$900 each), but no further filler is needed for many years. So, the 5-year cost can be lower with Bellafill than with repeat HA fillers yearly.

For example, three syringes of Bellafill at $900 = $2700 total (with results lasting 5+ years), whereas three syringes of HA over 3 years at $650 = $1950, and you’d likely need more beyond 3 years. So, we discuss these long-term cost-benefit aspects, too.

Value of Combination: While combining treatments costs more initially, it can sometimes reach results faster than doing one modality at a time spread over the years. For instance, spending $2000 on a filler+laser combo in a single year might get rid of scars that otherwise might take several incremental treatments over a more extended period.

Many clients find it worth investing upfront for a significant change rather than smaller amounts over a long time with incremental changes.

Frequently Asked Questions (FAQs) about Acne Scars Correction with Dermal Fillers: Your Expert Guide

Q1: Can fillers treat acne scars?

Respuesta concisa: Dermal fillers can effectively reduce the appearance of acne scars.

Respuesta detallada: Dermal fillers can significantly improve acne scars, incredibly depressed or atrophic scars. Fillers like hyaluronic acid or collagen stimulators fill the depressions, lifting and smoothing the skin surface to achieve a more even texture.

Although results can be immediate, they typically last several months to a year, depending on the filler used and individual skin conditions.

Q2: Are fillers or lasers better for acne scars?

Respuesta concisa: It depends on scar type; both fillers and lasers can be effective.

Respuesta detallada: Fillers are typically best for individual deep or depressed scars needing volume restoration, while laser treatments effectively improve overall skin texture, shallow scars, and discoloration. Combining fillers and laser therapy often provides optimal results for comprehensive scar treatment.

Q3: What is the best filler for pitted acne scars?

Respuesta concisa: Hyaluronic acid-based fillers are generally best for pitted acne scars.

Respuesta detallada: Hyaluronic acid fillers like JuvédermJuvéderm or Restylane are highly recommended for pitted acne scars due to their safety, reversibility, and effectiveness in adding volume and smoothing skin texture. They provide immediate improvement, can stimulate natural collagen production, and have minimal downtime.

Q4: Does hyaluronic acid remove acne scars?

Respuesta concisa: It doesn’t remove scars but significantly reduces their appearance.

Respuesta detallada: Hyaluronic acid fillers help improve acne scars by adding volume beneath the scar tissue, thus raising the depressed areas to create a smoother skin surface. However, they do not permanently remove scars; maintenance treatments are typically required for sustained results.

Q5: What are the side effects of filler for acne scars?

Respuesta concisa: Side effects include Redness, swelling, bruising, and rarely lumps or allergic reactions.

Respuesta detallada: Common side effects after dermal filler treatment include temporary Redness, swelling, bruising, and tenderness at the injection sites. Serious but rare side effects include allergic reactions, infection, lumps, or uneven texture. Proper technique by a trained professional minimizes risks significantly.

Q6: How do you fill in acne scars with makeup?

Respuesta concisa: Use primer, concealer, and foundation strategically to minimize scars.

Respuesta detallada: Start with a smoothing primer to even out skin texture, followed by a color-correcting concealer to neutralize discoloration. Apply a full-coverage foundation gently over the scarred areas and set it with translucent powder.

Choose products specifically designed to blur imperfections and ensure longer-lasting coverage.

Q7: How many syringes of filler for acne scars?

Respuesta concisa: Usually, 1-3 syringes depending on scar severity.

Respuesta detallada: The number of syringes required typically ranges from 1 to 3, based on the depth, number, and size of the scars. Shallow scars might need just one syringe, whereas extensive and deeper scars often require additional volume for optimal correction.

Q8: How do you fade back acne scars?

Respuesta concisa: Use exfoliating treatments, topical creams, and laser therapy.

Respuesta detallada: Fading back acne scars involves treatments such as chemical exfoliants (AHAs, BHAs), topical creams containing ingredients like retinol or vitamin C, chemical peels, and laser treatments. Consistent cuidado de la piel routines combined with professional procedures accelerate scar fading effectively.

Q9: Is subcision with fillers permanent?

Respuesta concisa: Results are long-lasting but not necessarily permanent.

Respuesta detallada: Subcision combined with fillers offers long-term improvement by breaking fibrous scar bands and providing volumetric support. While the procedure can significantly reduce scar appearance for several years, maintenance treatments might still be necessary as skin ages and filler degrades.

Q10: What injections are given for acne scars?

Respuesta concisa: Dermal fillers, steroids, and PRP injections.

Respuesta detallada: Common injections for acne scars include dermal fillers (hyaluronic acid, collagen stimulators), corticosteroids for raised scars, and Platelet-Rich Plasma (PRP), which promotes collagen production and skin healing. Each injection type addresses specific types of acne scars effectively.

Q11: Does a chemical peel help with acne scars?

Respuesta concisa: Chemical peels can improve mild to moderate acne scars.

Respuesta detallada: Chemical peels remove the damaged top layers of skin, stimulating cell regeneration and collagen production. They are particularly beneficial for superficial scars, uneven texture, and pigmentation.

Deeper scars may require more aggressive or combined treatments.

Q12: How long do dermal fillers for scars last?

Respuesta concisa: Typically, 6-18 months, depending on the filer used.

Respuesta detallada: The longevity of dermal fillers for scars ranges from 6 to 18 months. Hyaluronic acid fillers usually last 6 to 12 months, whereas collagen stimulators like Sculptra can last up to two years.

Lifestyle factors, metabolism, and individual responses affect the duration.

Q13: Are indented acne scars permanent?

Respuesta concisa: Without treatment, indented scars are typically permanent.

Respuesta detallada: Indented acne scars generally remain permanent if untreated due to damage and loss of underlying collagen. However, effective treatments like fillers, lasers, and subcision can improve their appearance and restore skin texture.

Q14: Can I get fillers if I have acne?

Respuesta concisa: It’s generally advisable to treat active acne first before getting fillers.

Respuesta detallada: Ideally, active acne should be managed and controlled before filler treatment, as injecting fillers during active breakouts can increase the risk of infection and inflammation. Clearing active acne reduces complications and improves overall outcomes.

Q15: Can I get fillers if I have acne?

Respuesta concisa: Treat acne first; fillers afterward for best outcomes.

Respuesta detallada: It is strongly recommended that active acne be controlled and cleared before proceeding with dermal fillers. Active acne increases the risk of complications, such as infection or inflammation post-procedure.

Addressing acne first ensures a safer and more effective treatment experience.
