Acne Scars

Acne scars — including ice pick, boxcar, and rolling types — form when severe breakouts damage the deeper layers of skin. Professional treatments like RF microneedling, laser resurfacing, and collagen-stimulating injectables can significantly improve texture and tone.

The Scars That Stay After Acne Clears

Acne breakouts heal. Acne scars often do not — not on their own, and not with the same timeline. Ice pick scars, rolling depressions, and boxcar pits are structural changes in the dermis: the collagen-rebuilding process after severe inflammation produced either too little (leaving a pit) or too much (leaving a raised mark). Surface skincare cannot reach them. The wrong treatment — ablative laser on darker skin, for example — can create a new color problem on top of a texture problem. Getting this right starts with correctly classifying what you actually have.

At Desert Bloom, Dr. Natalya Borakowski, NMD distinguishes between true atrophic scars (structural, requiring collagen remodeling) and post-inflammatory hyperpigmentation — PIH — which is a pigment response, not a textural defect. Both commonly follow acne, but they require completely different treatment paths. She assesses scar sub-type, Fitzpatrick skin type, scar age, and whether active acne is still contributing before building any plan.

Scars from surgery, trauma, or burns belong on the Scars hub. For active breakouts still occurring, see Acne. Color-only marks without any textural component fall under Hyperpigmentation.

At a Glance

Scope. Five primary treatment routes cover most acne scar presentations at Desert Bloom: RF Microneedling (Virtue RF — first-line for rolling and boxcar, safe across all Fitzpatrick types), CO2 Laser (deep ice pick and severe boxcar, Fitz I–III only), Microneedling with PRP (newer or mild scars, bridging), Bellafill PMMA filler (FDA-approved for atrophic acne scars — distensible boxcar and rolling that haven’t fully responded to energy devices), and Custom Chemical Peel (PIH, flat discoloration). Subcision for tethered rolling scars is a specialist add-on discussed at consultation.

Provider & candidacy. Dr. Natalya Borakowski, NMD oversees all acne scar planning. RF Microneedling is safe across Fitzpatrick I–VI — including skin tones where ablative laser carries meaningful PIH risk. CO2 and Erbium laser are reserved for Fitzpatrick I–III. For Fitzpatrick IV–VI patients with post-inflammatory hyperpigmentation, the non-laser brightening route (PRX-T33, Dermaquest peels, iontophoresis) is the correct path. Active acne should be controlled before starting scar treatment.

Downtime & how to start. Microneedling with PRP and chemical peel: minimal. RF Microneedling: 24–48 hours redness. Erbium: 3–7 days. CO2 laser: 7–14 days. Bellafill: minimal (injectable, bruising possible). A consultation with Dr. B maps scar sub-type, skin tone, and readiness before any treatment series is scheduled — there is no universal acne scar protocol.

The Four Acne Scar Types

Not all acne scars are the same — and treating the wrong type with the wrong method produces worse results, not better ones. Acne scarring falls into four clinical categories, each defined by how the skin responded to inflammatory damage during the breakout. The first step at a Desert Bloom consultation is identifying which type (or combination of types) is present, because that classification determines the entire treatment plan.

Ice Pick Scars

Narrow, deep channels extending well into the dermis — the result of a hair follicle or cyst rupturing and destroying tissue straight down. The opening at the surface is small but the depth makes ice pick scars among the hardest acne scars to treat. Most resurfacing modalities cannot reach the full depth of the damage in a single session. The TCA CROSS technique (focal high-concentration acid applied precisely into the channel) is one of the few approaches that specifically targets this morphology.

Route to: RF Microneedling series (all Fitz) + TCA CROSS or CO2 for deepest channels (Fitz I–III)

Rolling Scars

Wide, shallow to moderate depressions with sloping edges — not sharply defined — that give the skin a wave-like, undulating appearance. Rolling scars form when fibrous tethering bands develop under the skin surface, anchoring the dermis downward. The surface is not missing collagen so much as being pulled down from below. This means that while collagen remodeling helps, the most complete improvement often requires releasing the subdermal bands through subcision (a needle technique that cuts the tethering fibers) before or alongside energy treatment.

Route to: RF Microneedling — all Fitz (first-line); subcision consult for tethered rolling scars

Boxcar Scars

Round or oval depressions with sharply defined vertical walls and a flat base — like a box pressed into the skin. Depth varies from shallow (mostly epidermal) to deep (extending into the mid-dermis). The most clinically important distinction for boxcar scars is whether they are distensible: if the base of the scar rises when the surrounding skin is stretched, the depression is primarily a volume deficit rather than a surface texture problem. Distensible boxcars are excellent candidates for Bellafill (PMMA filler, FDA-approved for atrophic acne scars), which fills the deficit immediately while stimulating long-term collagen. Non-distensible boxcars need resurfacing.

Route to: Bellafill for distensible; RF Microneedling → CO2/Erbium for non-distensible (Fitz I–III)

PIH — Post-Inflammatory Hyperpigmentation

Post-inflammatory hyperpigmentation is not a scar in the structural sense — it is a pigment response. The melanocytes over-produce melanin in response to acne inflammation, leaving a flat brown or tan mark on the surface. The skin beneath is smooth; there is no collagen deficit or depth to treat. PIH fades on its own over 3–24 months, faster with targeted brightening treatment. This is the most frequent source of patient confusion: a flat dark mark after a pimple is often called a “scar” but is actually PIH — and the treatment path diverges completely from atrophic scar treatment.

Route to: Chemical Peel + brightening topicals (all Fitz) — PRX-T33 / Dermaquest for Fitz IV–VI; NO ablative laser

PIH vs. Atrophic Scars — Two Different Problems

The most common error in acne scar treatment — from patients and providers alike — is treating every dark or imperfect mark after acne as the same problem. PIH (post-inflammatory hyperpigmentation) is a color problem: the skin surface is flat, smooth, and structurally intact, but the melanocytes misfired and left a brown or red mark. An atrophic scar is a structural deficit: the dermis lost collagen and the surface is pitted, depressed, or uneven in texture. These two conditions often occur at the same site after a severe breakout, which is where the confusion compounds — a patient can have both a pitted boxcar scar and overlying PIH discoloration in the same spot.

The treatment path splits completely at this fork. PIH responds to brightening chemistry — chemical peels with alpha hydroxy acids or mandelic acid, lightening serums, PRX-T33 and Dermaquest peel protocols for darker skin tones. For Fitzpatrick IV–VI patients with PIH, ablative laser and IPL are contraindicated: they add thermal or light-based inflammation to already-reactive melanocytes and can worsen the hyperpigmentation significantly. The non-laser brightening route is both safer and more effective for this presentation. Atrophic scars, by contrast, need collagen remodeling — RF Microneedling, Erbium, CO2, or Bellafill filler. No amount of brightening treatment will fill a pitted depression. When both co-exist, the atrophic scar treatment usually leads; collagen remodeling often improves the overlying PIH as a secondary benefit, and any remaining discoloration is addressed with a peel series afterward.

PIH — Pigment / Color Route

Flat surface, no pit or texture. The problem is in the epidermis — pigment chemistry, not collagen architecture. Do not use ablative laser on Fitzpatrick IV–VI for this presentation.

Custom Chemical Peel — All Skin TonesAHA-based and mandelic acid formulations address epidermal pigment residue. Safe across Fitzpatrick types at appropriate peel depth. Best as standalone for flat PIH or as a finisher after resurfacing.
PRX-T33 + Dermaquest — Fitz IV–VI SpecificFor darker skin tones where IPL and ablative laser are contraindicated. PRX-T33 bio-revitalization followed by Dermaquest peel protocol and iontophoresis delivers brightening results without triggering the melanocyte-stimulating inflammation that laser would create.
SPF 30+ Daily — Non-Negotiable Alongside Any RouteUV exposure is the single biggest driver of PIH recurrence and slowing. Broad-spectrum sunscreen applied daily is part of every PIH plan — without it, in-office results are consistently undermined.

Atrophic Scar — Texture / Structure Route

Pitted, depressed, or volume-deficit surface. The dermis lost collagen. Treatment must reach and remodel the structural deficit — brightening peels do not.

RF Microneedling — All Fitz, First-LineSafe across Fitzpatrick I–VI. Radiofrequency energy delivered through microneedles into the dermis — collagen remodeling without surface ablation. 3–4 sessions covers most rolling and boxcar presentations regardless of skin tone.
Bellafill (PMMA Filler) — Distensible Boxcar and RollingFDA-approved specifically for atrophic acne scars. Fills the volume deficit immediately while PMMA microspheres stimulate ongoing collagen at the scar floor. Best for scars that have plateaued with energy devices or patients wanting immediate correction.
CO2 Laser — Deep Ice Pick and Severe BoxcarMost aggressive resurfacing option. Reserved for Fitzpatrick I–III — ablative energy on Fitz IV–VI carries real PIH risk. 7–14 days downtime. Appropriate when RF Microneedling series has not achieved enough improvement in deeper scars.

Treatment Options for Acne Scars at Desert Bloom

Most acne scar plans at Desert Bloom start with RF Microneedling and layer in targeted modalities based on scar sub-type, skin tone, and how the skin responds over time. The five primary routes below each have a distinct role and a clear patient profile. One option — Bellafill — is worth singling out because it is the only FDA-approved injectable filler specifically for atrophic acne scars, which makes it a different category from the energy-based treatments.

RF Microneedling for acne scars — Virtue RF at Desert Bloom Scottsdale
RF Microneedling (Virtue RF) — First-Line for Most Atrophic ScarsFor rolling and boxcar acne scars — and mixed presentations — RF Microneedling is where Dr. Borakowski typically starts. Radiofrequency energy travels through microneedles directly into the dermis to remodel scar tissue without ablating the surface. That distinction matters for skin tone: it is safe and effective across Fitzpatrick I–VI, including darker skin tones where CO2 laser carries real post-inflammatory hyperpigmentation risk. Most patients need 3–4 sessions spaced 4–6 weeks apart. Clinical studies show 50–80% improvement in rolling and boxcar scars over a series.Best for: rolling + boxcar — all Fitz I–VI, mixed presentations · See RF Microneedling →
CO2 Laser Resurfacing for deep acne scars — Fitz I–III only
CO2 Laser — Deep Ice Pick and Severe BoxcarWhen scars are deep and mature and RF Microneedling alone has not been enough, CO2 laser is the escalation. Ablation removes damaged tissue layer by layer and triggers the most aggressive collagen remodeling response available non-surgically. Reserved for Fitzpatrick I–III — surface ablation carries real PIH risk in darker skin. Requires 7–14 days downtime but produces the highest single-session improvement ceiling for severe acne scarring. An escalation tool, not a starting point.Best for: deep ice pick, severe boxcar — Fitz I–III only · See CO2 Laser →
Microneedling with PRP for newer acne scars
Microneedling with PRP — Newer Scars and BridgingFor acne scars still in early stages (under 12 months old), mild surface texture, or as a bridge between heavier RF or laser sessions. Microneedling creates controlled collagen-induction microchannels; platelet-rich plasma drawn from the patient’s own blood is applied topically to enhance healing. Less powerful than RF Microneedling in the dermis — not appropriate for deep pitting — but a gentle and safe starting point across all Fitzpatrick types with minimal downtime.Best for: newer scars (<12 mo), mild texture, bridging — all Fitz · See Microneedling →
Bellafill PMMA filler for atrophic acne scars — FDA approved
Bellafill (PMMA) — FDA-Approved Injectable for Atrophic Acne ScarsBellafill is the only FDA-approved dermal filler specifically indicated for atrophic acne scars. It contains PMMA (polymethylmethacrylate) microspheres suspended in a collagen gel — the collagen gel provides immediate volume correction while the PMMA microspheres stimulate the body’s own ongoing collagen production at the scar floor. Best suited for distensible boxcar and rolling scars where the volume deficit is the primary problem, and for patients who have plateaued with energy-based treatment. Results are long-lasting. Downtime is minimal — injection-site bruising possible.Best for: distensible boxcar + rolling, scars plateaued on energy devices — all Fitz · See Bellafill →
Custom Chemical Peel for PIH and surface discoloration after acne
Custom Chemical Peel — PIH and Surface DiscolorationWhen the post-acne concern is flat brown or red discoloration rather than a textural pit — or when PIH persists after a resurfacing series — a chemical peel addresses what lasers were not designed for. AHA-based and mandelic acid formulations work at the epidermal level to even out pigment residue. Safe across all Fitzpatrick types at appropriate peel depth. An adjunct for the atrophic scar route, or a standalone treatment for pure PIH cases where the surface is smooth.Best for: PIH, flat discoloration, color concern after resurfacing — all Fitz · See Chemical Peel →

Safety, Skin Type, and Timing

Acne scar treatment has hard rules around skin tone, scar age, and whether active acne is still present. The most common clinical errors are treating with ablative laser on Fitzpatrick IV–VI skin (adding a color problem to a texture problem), treating while breakouts are still active (generating new scars and inflammation during treatment), and treating scars that are still remodeling (under six months old). These three situations each require a different approach before aesthetic scar treatment is appropriate.

When NOT to Start Acne Scar Treatment

Active acne flare — treat acne first. Energy devices and chemical peels applied over active inflammatory acne worsen outcomes and can create new scarring from the treatment itself. Stabilize breakouts for at least 1–3 months before scheduling any scar treatment. The consult can happen sooner — the treatment starts when the acne is controlled.

Fitzpatrick IV–VI + PIH — no ablative laser. CO2 and Erbium ablative laser are contraindicated for post-inflammatory hyperpigmentation in darker skin tones. Thermal and light-based energy applied to already-reactive melanocytes can significantly worsen hyperpigmentation. The safe and effective path for PIH in Fitz IV–VI is the non-laser brightening route: PRX-T33 bio-revitalization, Dermaquest peel protocol, iontophoresis, brightening topicals. RF Microneedling remains safe across all Fitzpatrick types for the atrophic scar component.

Scars under 6 months old — wait for stability. Acne scars still in active remodeling are not ready for aggressive treatment. The collagen-breakdown and rebuilding cycle takes roughly 6–12 months to stabilize after a severe breakout. Treating during this window can worsen depth and texture. The exception: mild microneedling or a gentle peel series while waiting for the scar to mature is often acceptable, and can help limit PIH in the interim.

Frequently asked questions

Can acne scars be completely removed? Most acne scars can be made significantly less noticeable — often 50–80% improvement over a treatment series — but full erasure to the level of surrounding skin is uncommon, particularly for deep ice pick scars and long-standing severe boxcar scarring. Newer scars, mild rolling scars, and distensible boxcar scars treated with Bellafill often come very close to complete correction. The consultation is the time to set realistic expectations for your specific scar type, depth, and skin tone.
What is the difference between PIH (dark marks) and actual acne scars? Post-inflammatory hyperpigmentation (PIH) is a flat discoloration — the skin surface is smooth, but the melanocytes over-produced melanin in response to inflammation, leaving a brown or tan mark. PIH fades over time (3–24 months) and responds well to brightening treatments. An atrophic acne scar is a structural deficit — a pit, depression, or textural irregularity caused by collagen loss. No brightening peel or topical will fill a pitted depression; resurfacing or filler is required. Many patients have both at the same site — a pitted boxcar scar with overlying PIH discoloration. Correct identification determines which treatment leads.
Is Bellafill a good option for acne scars? Bellafill is the only FDA-approved injectable filler specifically indicated for atrophic acne scars. It works best for distensible boxcar and rolling scars — where the primary problem is a volume deficit that can be corrected with fill. PMMA microspheres in the filler stimulate long-term collagen production at the scar floor, extending the result. Bellafill is not ideal for ice pick scars (too narrow for filler correction) or non-distensible boxcar scars (resurfacing is more appropriate). It is also used for patients who have plateaued with energy devices and want additional improvement.
What is the best treatment for ice pick scars? Ice pick scars are among the most difficult acne scars to treat because of their narrow diameter and depth. The TCA CROSS technique (focused application of high-concentration trichloroacetic acid directly into the channel) specifically targets the morphology. For Fitzpatrick I–III patients, CO2 or Erbium laser can reach deeper into the channel than RF Microneedling. RF Microneedling still produces meaningful improvement in a series and is the appropriate choice for darker skin tones. Most ice pick scar plans use a combination of approaches over multiple sessions — no single treatment resolves them completely in one visit.
Can acne scars be treated on darker skin — Fitzpatrick IV–VI? Yes — but the treatment plan is different. RF Microneedling is safe and effective across all Fitzpatrick types, including IV–VI, because it delivers energy through needles into the dermis without ablating the surface. Ablative CO2 and Erbium laser are contraindicated for Fitz IV–VI acne scar patients because surface ablation can trigger post-inflammatory hyperpigmentation. For PIH specifically on darker skin, the non-laser brightening route (PRX-T33, Dermaquest peels, iontophoresis) is both safer and more effective than laser or IPL. Bellafill and Microneedling with PRP are also safe across all skin tones.
Do I need to wait until my acne is completely gone before treating scars? Active inflammatory breakouts should be controlled before starting scar treatment — not necessarily completely eliminated, but stable. Treating over active acne creates new inflammation, can worsen existing scarring, and reduces treatment effectiveness. Dr. Borakowski typically wants to see at least 1–3 months of controlled breakouts before starting a scar series. The consultation can happen sooner — it is a good time to map what you have and build the plan while acne management is in progress.
How many sessions does acne scar treatment take? It depends on scar type, severity, and the treatment selected. RF Microneedling plans typically involve 3–4 sessions spaced 4–6 weeks apart, with the full collagen remodeling benefit visible 3–6 months after the final session. CO2 laser may only need 1–2 sessions but requires longer recovery per session. Bellafill is typically 1–2 sessions. Mild presentations and newer scars may respond in fewer sessions; severe or mixed-type scarring often requires a longer series and combination approach. There is no single-session solution for moderate to severe acne scarring.

Working With Dr. Borakowski on Acne Scars

Dr. Natalya Borakowski, NMD has treated acne scarring for over twenty years, and the clinical judgment required here — which scar type, which skin tone, which treatment in which sequence — is the kind of pattern recognition that compounds with experience. A consultation that skips the classification step and goes straight to recommending “laser” or “microneedling” without mapping the sub-type, the Fitzpatrick number, and the scar’s age is a consultation that will produce inconsistent outcomes. She starts every acne scar appointment with the classification before any treatment plan is discussed.

She is also deliberate about contraindications. Patients with active acne are told to stabilize breakouts first. Darker-skin patients with PIH are routed to the non-laser brightening protocol — not pushed toward ablative laser because it is higher-revenue or more familiar. Scars that are still maturing are counseled to wait. The goal is a plan that is right for the scar in front of her, not a standard package applied to every patient who books a scar consult.

“Acne scars are the one area where I see the most mismatched treatments — laser on the wrong skin tone, energy devices on scars that need filler, brightening peels on pitted skin that needs collagen remodeling. The consult is where we sort that out. Most patients see meaningful improvement when we treat the right problem with the right tool.”

Ready to Understand Your Acne Scar Options in Scottsdale?

A scar consultation at Desert Bloom starts with classification — scar type, skin tone, scar age, and whether active acne is still a factor — before any treatment is proposed. There is no standard acne scar package. The plan depends entirely on what you actually have.

Complimentary 30-minute consultations are available. No obligation to start a treatment series. If Dr. Borakowski concludes that your acne needs to be better controlled before scar treatment begins, or that a specialist referral (subcision, for example) should be part of the plan, she will tell you at the first visit.
