Getting rid of severe acne scars is possible, but it almost always requires professional treatment, and often a combination of approaches. The type of scar you have determines which treatments will actually work, so understanding what you’re dealing with is the first step toward visible improvement.
Identify Your Scar Type First
About 80 to 90 percent of acne scars involve a net loss of collagen in the skin, leaving indented (atrophic) marks. These fall into three categories:
- Ice pick scars make up 60 to 70 percent of atrophic scars. They’re narrow (under 2mm), V-shaped, and punch deep into the skin. They look like someone poked the surface with a sharp tool.
- Boxcar scars account for 20 to 30 percent. These are wider (1.5 to 4mm), round or oval, with sharp vertical edges, almost like a small crater. Shallow ones respond well to resurfacing; deep ones are more stubborn.
- Rolling scars make up 15 to 25 percent. These are the widest, reaching up to 5mm across, and create a wave-like, uneven texture. They’re caused by bands of scar tissue pulling the skin down from underneath.
A smaller number of people develop raised scars, either hypertrophic scars that stay within the original wound boundary or keloids that grow beyond it. These result from excess collagen production rather than collagen loss, and they require a completely different treatment strategy.
Laser Resurfacing for Moderate to Severe Scarring
Laser treatments are among the most effective options for atrophic acne scars, particularly boxcar and rolling types. They work by removing damaged surface skin and heating the deeper layers, which triggers your body to produce fresh collagen and elastin as the skin heals.
The two main ablative lasers are CO2 and erbium. CO2 lasers penetrate deeper and remove the outer skin layer entirely while partially reaching into the dermis beneath it. This makes them powerful for deeper scars but also means more downtime: expect 5 to 10 days of redness, swelling, and peeling before you look presentable again. Erbium lasers have a stronger attraction to water in the skin, which allows them to ablate tissue more precisely with less heat damage to surrounding areas. Recovery tends to be slightly shorter.
Fractional versions of both lasers treat only a fraction of the skin’s surface in a grid-like pattern, leaving tiny columns of untouched skin between treatment zones. This speeds healing considerably compared to older full-field lasers. The average cost of a laser resurfacing session is around $1,829, according to the American Society of Plastic Surgeons, though prices vary widely by location, provider, and how aggressive the treatment is. Most people need two to four sessions spaced several weeks apart.
Microneedling and Radiofrequency
Radiofrequency microneedling uses tiny needles that penetrate the skin and deliver heat energy at controlled depths. This creates micro-injuries that prompt new collagen production while the radiofrequency energy tightens existing tissue. A typical protocol involves four sessions spaced about three weeks apart, with a follow-up evaluation a month after the last session.
Practitioners adjust needle depth based on scar type. For deep scars, the first pass uses higher energy and deeper penetration, while a second pass at lower settings addresses shallower scars and overall texture. Needle lengths of 0.6mm and 1mm are common, selected according to the depth of individual scars. Recovery is generally easier than ablative laser, with redness lasting a few days rather than a week or more. This makes it a good middle-ground option for people who want meaningful improvement without extended downtime.
Subcision for Tethered, Rolling Scars
Rolling scars look the way they do because fibrous bands of scar tissue anchor the surface skin down to deeper tissue. No amount of resurfacing will fix this if the tethering underneath remains intact. Subcision addresses the root cause: a needle is inserted beneath the scar to physically break those fibrous strands, releasing the skin so it can rise back to the level of the surrounding surface.
Subcision is often combined with a filler to prevent the bands from reattaching. Bellafill is the only FDA-approved filler specifically indicated for acne scars. It contains tiny permanent microspheres suspended in a collagen carrier. The collagen provides immediate volume that gets absorbed over about a month, while the microspheres stimulate your body to produce its own collagen permanently around them. Other temporary fillers made of hyaluronic acid can also be used, though they’ll dissolve over 6 to 18 months and may need repeat injections.
TCA CROSS for Ice Pick Scars
Ice pick scars are notoriously difficult to treat with lasers or microneedling because they’re so narrow and deep. The most targeted approach is a technique called TCA CROSS, where a high concentration of trichloroacetic acid (up to 100%) is applied directly into individual ice pick scars using something as precise as a wooden toothpick. The acid causes a controlled chemical injury at the base of the scar, triggering the body to fill it in with new collagen from the bottom up.
A typical course involves four sessions spaced about two weeks apart. After each treatment, a small crust forms over the treated scar by the next day and falls off within three to four days for most people, though it can occasionally last up to a week. The scar gradually becomes shallower with each session. This technique works poorly on wide scars but is one of the few treatments that can meaningfully improve the deepest ice pick marks.
Chemical Peels for Broader Texture Issues
Chemical peels remove damaged outer skin to reveal smoother skin underneath. For acne scars, medium-depth peels are more effective than superficial ones, as they reach deeper into the skin to stimulate collagen remodeling. Downtime is typically 3 to 7 days of mild peeling and redness. Peels work best on shallow boxcar scars and general texture irregularities rather than deep individual scars. They’re often used as a complement to more targeted treatments like subcision or laser rather than as a standalone solution for severe scarring.
At-Home Topical Treatments
Prescription retinoids can modestly improve shallow acne scars over time. Adapalene and tretinoin both stimulate collagen production in the skin, and studies have shown increased levels of new collagen fibers after consistent use. In one clinical trial, adapalene 0.3% improved skin texture and the appearance of atrophic scars over 24 weeks, with tissue analysis confirming actual collagen remodeling rather than just a surface-level effect.
The reality check: topical treatments work slowly and produce subtle results. You’re looking at a minimum of six months of consistent daily use to see texture changes, and the improvement will be modest compared to professional procedures. Retinoids are most useful for preventing new scars from worsening, smoothing mild texture issues, and maintaining results after professional treatment. They won’t transform deep scarring on their own.
Treatment Considerations for Darker Skin
If you have a medium to dark skin tone, treatment selection becomes especially important. Up to 90% of acne patients with darker skin experience post-inflammatory hyperpigmentation, the dark marks that linger after any skin injury or inflammation. Aggressive treatments that generate excessive heat can stimulate pigment-producing cells and leave you with discoloration that looks worse than the original scars.
Non-ablative lasers are generally safer for darker skin tones than ablative ones. A newer generation of 1550nm non-ablative lasers with integrated cooling systems has shown equivalent improvement across all skin tones with minimal adverse events. The cooling component is critical: it protects the skin surface from excess heat that would otherwise trigger pigmentation changes. In clinical testing, there was no statistically significant difference in adverse event rates between lighter and darker skin types when this cooling technology was used.
Microneedling (with or without radiofrequency) is another relatively safe option for darker skin because it creates mechanical injury rather than relying primarily on light absorption, which varies with skin pigment. If you have darker skin and are considering any scar treatment, the specific device, settings, and your provider’s experience treating similar skin tones all matter significantly.
Raised Scars Need a Different Approach
If your scars are raised rather than indented, the treatments above can actually make them worse. Hypertrophic and keloid scars respond to a different set of interventions. Silicone gel sheets are a first-line option: they’re worn over the scar for up to 24 hours a day, can be washed and reused, and a typical treatment cycle runs 8 to 12 weeks. The mechanism isn’t fully understood, but the occlusion and hydration appear to help flatten and soften raised tissue. Corticosteroid injections directly into the scar are another common approach, gradually breaking down excess collagen to reduce the scar’s height and firmness.
Combining Treatments for the Best Results
Severe acne scarring rarely responds to a single treatment modality. Most dermatologists recommend a combination approach tailored to the specific mix of scar types on your face. A common strategy might involve subcision to release tethered rolling scars, TCA CROSS for ice pick scars, and fractional laser or microneedling to smooth the overall surface texture. These can be done in sequence or sometimes in the same session.
Total treatment timelines for significant improvement typically span 6 to 12 months when you factor in multiple sessions and healing time between them. Complete elimination of deep scars is rarely possible, but a well-planned combination approach can reduce their visibility by a meaningful degree, often enough that scars are no longer noticeable at conversational distance.
