Getting rid of acne scars is possible, but it takes the right treatment matched to the right scar type, and realistic expectations about timing. Most people see meaningful improvement within three to six months, though mixed scarring often requires a staged plan running six to twelve months. The approach that works best for you depends on whether your scars are shallow or deep, wide or narrow, and whether your skin tone puts you at risk for discoloration after treatment.
Identify Your Scar Type First
Not all acne scars respond to the same treatment. Scars fall into two broad camps: depressed (atrophic) scars, where tissue was lost during healing, and raised scars, where the body overproduced collagen. Most people dealing with acne scars have the depressed kind, which come in three forms.
Ice pick scars are small, narrow indentations that point down into the skin like a puncture. They’re the deepest relative to their size and the hardest to treat with surface-level methods. Boxcar scars are broader depressions with sharply defined, box-like edges. Rolling scars have sloping edges and varying depth, giving the skin a wavy, uneven texture. Rolling scars tend to respond best to treatments that release the scar tissue underneath, while ice pick scars often need targeted, high-concentration techniques to rebuild skin from the bottom up.
Raised scars, including keloids (scar tissue that grows beyond the original wound), are more common in people with darker skin tones. Keloids require a completely different treatment strategy than depressed scars, so getting an accurate assessment matters before committing to any procedure.
Laser Resurfacing
Laser treatments are among the most effective options for moderate to severe atrophic scars. They work by removing damaged surface skin, stimulating collagen production deeper down, or both. The two main categories are ablative lasers, which vaporize the outer skin layers, and non-ablative lasers, which heat the tissue underneath without breaking the surface.
Ablative lasers, particularly the CO2 laser, are considered the most powerful. One study reported 81.4% improvement in moderate atrophic scars. The trade-off is a roughly two-week recovery period with redness, swelling, and skin that looks raw before it heals. Improvement continues building for up to a year after the procedure as new collagen matures.
The erbium YAG laser offers comparable results with less downtime, less discomfort, and faster healing, though it produces slightly less skin tightening than CO2. For people who can’t take extended time off, fractional lasers split the beam into thousands of tiny columns, treating a fraction of the skin at a time. Fractional resurfacing improves acne scars faster and to a greater extent than older non-ablative techniques, with shorter recovery between sessions.
Non-ablative options like the 1450-nm diode laser can improve scarring without breaking the skin surface at all. In comparative studies, the diode laser outperformed other non-ablative devices for atrophic facial scars, making it a reasonable middle-ground option.
Microneedling and Radiofrequency
Microneedling uses fine needles to create controlled micro-injuries in the skin, triggering your body’s wound-healing response and new collagen production. Radiofrequency (RF) microneedling adds heat energy delivered deep into the dermis, amplifying the collagen-building effect beyond what needles alone achieve.
Most people need three to six sessions spaced four to six weeks apart. That means a full treatment course runs roughly three to nine months from start to finish, with results continuing to improve between sessions as collagen remodels. RF microneedling is a popular choice because it works on a wide range of scar types without the extended downtime of ablative lasers. Expect a day or two of redness and mild swelling after each session.
Chemical Peels and TCA CROSS
Standard chemical peels can improve shallow scarring and post-acne discoloration by removing the outermost skin layers. For deeper scars, particularly ice pick scars, a specialized technique called TCA CROSS is far more effective. A dermatologist applies a high concentration of trichloroacetic acid (70% or higher) directly into individual scars using a fine applicator. This triggers intense collagen production at the base of each scar, gradually filling it from within.
Repeated sessions can normalize deep rolling and boxcar scars, with concentrations up to 100% used for the deepest ice pick scars. Side effects are mild: temporary redness or darker discoloration that fades within four to six weeks. TCA CROSS is often combined with other treatments like microneedling or lasers as part of a multi-step plan for mixed scarring.
Subcision
Rolling scars often have fibrous bands of scar tissue pulling the skin surface downward. Subcision involves inserting a small needle or blade beneath the scar to release those tethered bands, allowing the skin to lift back to its normal level. In a study of 45 patients, 95.6% saw at least one grade of improvement. Downtime is minimal: slight redness, swelling, and tenderness lasting one to two days.
Subcision works best for rolling scars and is not ideal for deep boxcar or ice pick scars. It’s frequently combined with fillers or microneedling in the same treatment plan, with subcision releasing the scar and a follow-up treatment building volume underneath.
Dermal Fillers
For scars that leave a visible depression, injectable fillers can restore volume beneath the scar to bring it level with surrounding skin. One filler is FDA-approved specifically for moderate to severe atrophic acne scars in adults 21 and older, with results lasting up to one year. Other commonly used fillers (hyaluronic acid and calcium-based options) can also be injected into acne scars but typically need repeat treatments every few months to maintain results. All soft-tissue fillers are temporary, lasting six months to two years depending on the product.
Fillers provide the most immediate visible improvement of any option on this list. They’re particularly useful for isolated deep scars or as a bridge treatment while longer-term collagen-building procedures take effect.
What Results Actually Look Like
Acne scar treatment is almost never a single appointment with dramatic before-and-after results. Here’s a realistic timeline for most procedures: early texture improvement appears at three to six weeks, when scars may look smoother in certain light. The real collagen-remodeling phase hits at three to six months, bringing shallower scars, less shadowing, and smoother skin under makeup. Mixed scarring that requires multiple treatment types often needs six to twelve months of staged procedures.
The goal for most people is significant improvement, not perfection. Even the most aggressive ablative lasers produce 50% to 90% improvement rather than complete elimination. Setting that expectation early makes the process less frustrating.
Protecting Your Results
UV exposure is the single biggest threat to your results. When skin is healing from acne or any scar treatment, inflammation triggers excess melanin production, leading to dark spots (post-inflammatory hyperpigmentation) that can last six to twelve months if you skip sun protection. Sun exposure darkens existing spots and creates new ones, effectively undoing the treatment you just paid for.
Use a broad-spectrum sunscreen with at least SPF 50 daily, even on cloudy days. Reapply every 90 minutes during direct sun exposure, or every two hours as a baseline. This isn’t optional post-treatment advice. It’s the difference between results that hold and results that fade into new discoloration.
Special Considerations for Darker Skin
People with darker skin tones face two additional risks: post-inflammatory hyperpigmentation and keloid formation. A single inflamed pimple can leave dark marks lasting months to years, and aggressive treatments can trigger the same problem if not calibrated properly. In more severe cases, procedures done incorrectly can worsen both scarring and discoloration.
Laser treatments, chemical peels, and microdermabrasion can all be effective for darker skin, but they should be performed by a dermatologist with specific expertise in treating darker skin types. Non-ablative and fractional lasers generally carry less risk than fully ablative lasers for higher Fitzpatrick skin types. The stakes of choosing the wrong provider or wrong settings are higher when your skin is prone to pigment changes, so this is one area where specialist experience matters more than price or convenience.
