Fractional lasers improve acne scars in rosacea patients

Key clinical point: A non-ablative fractional 1440-nm laser was safe and effective for improving the appearance of acne scars in rosacea patients.

Major finding: The 30 patients who completed the study reported significant reductions in acne scar scores from baseline to the end of three treatments (from 45 to 15); rosacea erythema scores improved from 2.1 to 1.9 with no increase in flushing, burning, or stinging.

Study details: The data come from a prospective, interventional study of 32 adults with rosacea and acne scars who underwent three sessions of 1440-nm NAFL therapy.

Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.
