How Are Acne Scars Treated?
Last reviewed: May 2026 · Haute MD Editorial Team
Acne scars are treated based on their type — atrophic scars (icepick, boxcar, rolling) respond best to procedures that stimulate collagen and resurface the skin, while hypertrophic and keloid scars require steroid injections, laser treatment, or surgical removal. The most effective treatments are laser resurfacing, microneedling with radiofrequency (Morpheus8), chemical peels, dermal fillers for volume loss, and subcision for tethered scars.
Types of acne scars
Atrophic scars (depressions in the skin) are the most common and include icepick scars (deep, narrow), boxcar scars (wide, defined edges), and rolling scars (wavy texture from tethered fibrous bands). Hypertrophic scars are raised and result from excess collagen production. Keloids are overgrown scars that extend beyond the original wound boundary.
Most effective treatments by scar type
Rolling scars respond best to subcision (releasing tethered bands) combined with filler or biostimulators. Icepick scars respond to TCA CROSS chemical reconstruction. Boxcar scars respond to ablative laser resurfacing and Fraxel. All atrophic scar types benefit from microneedling with radiofrequency (Morpheus8) and PRP.
How many treatments are needed?
Most patients require a series of 3-6 treatments for significant improvement. Results continue to improve for 3-6 months after each treatment as collagen remodeling continues.
Frequently Asked Questions
Can acne scars be permanently removed?
Acne scars can be significantly improved — often by 50-80% — but complete removal is rarely possible. Combination approaches (multiple modalities) produce the best outcomes.
What is the best laser for acne scars?
Fractional CO2 laser and Fraxel are the gold standard for resurfacing acne scars. Morpheus8 RF microneedling is effective for all skin tones with less downtime.
Does microneedling work for acne scars?
Yes. Microneedling stimulates collagen production and is effective for rolling and boxcar scars. Radiofrequency microneedling (Morpheus8) produces superior results compared to traditional microneedling.
Are acne scar treatments covered by insurance?
Cosmetic acne scar treatments are generally not covered by insurance. However, treatments for keloid scars or those causing functional issues may qualify for coverage.
