Getting rid of acne scars requires matching the right treatment to the right scar type, and most people see meaningful improvement with today’s options. Shallow scars can fade with consistent topical care at home, while deeper scars typically need professional procedures like microneedling, laser resurfacing, or subcision. The key is understanding what kind of scarring you’re dealing with, because a treatment that works well for one type can be ineffective for another.
Why Scar Type Matters
Acne scars fall into three main categories, each with a different structure beneath the skin. Ice pick scars are the most common, making up 60 to 70 percent of depressed acne scars. They’re narrow, V-shaped, and extend deep into the skin, sometimes reaching the fat layer below the dermis. Their depth and narrow opening make them the hardest type to treat with surface-level approaches.
Boxcar scars are wider, with round or oval shapes and sharp, defined edges. Think of them as small craters with vertical walls. Rolling scars, by contrast, have sloping edges that create a wave-like unevenness across the skin. If you gently stretch the skin and the scar flattens out, it’s likely a rolling scar. This distinction matters because rolling scars are caused by fibrous bands pulling the skin down from underneath, which means they respond well to treatments that release those bands. Boxcar and ice pick scars need different strategies.
What Topical Treatments Can Do
Topical products work best for shallow scarring, mild texture changes, and the dark marks left behind after breakouts (which are technically discoloration, not true scars). Prescription retinoids are the strongest topical option. They work by converting to retinoic acid in your skin cells, where they bind to receptors that regulate gene expression and stimulate collagen production. Over months of consistent use, this gradual collagen rebuilding can soften the edges of shallow scars and improve overall skin texture.
Over-the-counter retinol follows the same pathway but at lower potency, so results take longer. Products containing azelaic acid or vitamin C can help fade post-inflammatory dark spots, particularly when used alongside a retinoid. Be realistic about what topicals can achieve: they’re effective for surface-level improvements, but they won’t fill in a deep ice pick scar or release the tethered bands beneath a rolling scar. Think of them as a foundation that complements professional treatments rather than a replacement.
Microneedling for Broader Texture Improvement
Microneedling creates thousands of tiny punctures in the skin, triggering a wound-healing response that produces new collagen. It’s one of the more versatile scar treatments because it addresses texture across larger areas rather than targeting individual scars. Most treatment plans involve four sessions spaced three to four weeks apart, performed under local numbing cream.
Results vary depending on scar severity. In one study, about 18 percent of patients reported 75 to 100 percent improvement in their scarring, roughly a quarter saw 50 to 74 percent improvement, and the majority (55 percent) experienced 25 to 49 percent improvement. Those numbers reflect realistic expectations: microneedling makes scars noticeably better without making them disappear entirely.
Radiofrequency microneedling adds heat energy delivered through the needles into the deeper layers of skin. Traditional microneedling primarily affects the upper skin layers, while the RF version reaches the dermis, where it causes collagen fibers to contract and triggers a stronger healing response. This translates to firmer skin, improved elasticity, and deeper scar reduction. If your scars are moderate to severe, RF microneedling is often worth the higher cost because of that deeper tissue remodeling.
Laser Resurfacing for Deeper Scars
Fractional CO2 laser treatment removes controlled columns of damaged skin while leaving surrounding tissue intact, which speeds healing compared to older full-surface lasers. The laser vaporizes scar tissue and triggers significant collagen remodeling as the skin repairs itself. It’s one of the most effective single treatments for boxcar and rolling scars.
Recovery takes one to two weeks. During that time, treated skin forms a crust that gradually falls away on its own. Your skin will be red and sensitive for several weeks after the crust clears, and final results continue to develop over months as new collagen fills in. Most people need one to three sessions depending on scar depth, with sessions spaced several months apart to allow full healing between rounds.
The average cost of laser skin resurfacing is around $1,829 per session, according to the American Society of Plastic Surgeons. That figure doesn’t include facility fees, anesthesia, or prescription medications for recovery, so actual out-of-pocket costs are often higher. Insurance rarely covers scar treatment since it’s considered cosmetic.
Subcision for Rolling Scars
Rolling scars are caused by fibrous bands anchoring the skin surface to deeper tissue, creating that undulating, uneven look. Subcision directly addresses this. A needle is inserted beneath the scar and moved back and forth to physically break those fibrous strands. The release, combined with new collagen production from the wound-healing process, allows the skin to lift back to a normal level.
Subcision works particularly well when combined with other treatments. Some dermatologists follow subcision with microneedling in the same session to maximize collagen stimulation. Others pair it with fillers to provide immediate volume beneath the released scar. It’s a targeted technique, meaning it’s used on individual scars rather than across the entire face.
TCA CROSS for Ice Pick Scars
Ice pick scars are notoriously difficult because they’re so narrow and deep. A technique called TCA CROSS was designed specifically for them. It involves applying a high concentration (70 to 100 percent) of trichloroacetic acid directly into the base of each scar, causing controlled destruction that triggers the scar to rebuild from the bottom up with new collagen.
Patients can expect a one to two grade improvement in scar severity over a six-month period, typically requiring multiple sessions. It’s a simple in-office procedure with minimal downtime, and it’s one of the few treatments that can meaningfully reduce the depth of narrow, deep scars. It’s often used in combination with broader resurfacing treatments: TCA CROSS handles the individual deep scars while laser or microneedling improves the surrounding texture.
Dermal Fillers for Immediate Volume
Hyaluronic acid fillers can be injected directly beneath individual depressed scars to physically lift them to the level of surrounding skin. The result is immediate, which makes fillers appealing for people who want visible improvement without weeks of recovery. One case study documented sustained improvement lasting 24 months after a single hyaluronic acid treatment for an atrophic scar, without needing a repeat injection.
Fillers work best for wider, shallower depressions like boxcar and rolling scars. They’re less practical for ice pick scars because the opening is too narrow. Some dermatologists use fillers as a complement to subcision, injecting the filler into the space created after fibrous bands are released. This combination provides both immediate volume and long-term collagen remodeling.
Considerations for Darker Skin Tones
People with medium to dark skin tones face an additional challenge: post-inflammatory hyperpigmentation. Any treatment that creates inflammation or injury in the skin can trigger excess melanin production, leaving dark spots that may last months. This doesn’t mean aggressive treatments are off the table, but it does mean the approach needs to be more careful.
Before starting any scar treatment, active acne should be fully under control. Each new breakout can create another round of dark marks, undermining progress from treatment. Microneedling and lower-energy laser settings are generally safer starting points for darker skin than aggressive ablative lasers. Your provider should have specific experience treating your skin tone, because the energy settings, pre-treatment preparation, and post-care protocols that minimize hyperpigmentation risk differ meaningfully from standard approaches.
Building a Realistic Treatment Plan
Most people with moderate to severe acne scarring benefit from a combination of treatments rather than any single approach. A typical plan might start with subcision for tethered rolling scars, followed by a series of microneedling or laser sessions for overall texture, with TCA CROSS targeting any remaining deep ice pick scars. Topical retinoids are used throughout to support ongoing collagen production between sessions.
Timeline expectations matter. Collagen remodeling is a slow biological process. You’ll typically see initial improvement within a few weeks of a procedure, but results continue to develop for three to six months afterward. A full treatment plan spanning multiple procedures and healing intervals often takes six months to a year. The goal for most people isn’t scar-free skin but a significant enough reduction that scarring no longer draws attention or affects confidence. With the right combination of treatments, that’s an achievable outcome for the majority of scar types.
