A Short term acne flares can occur after laser resurfacing and having done many Fraxel laser treatments in the last 20 years I have had patients who I have seen with short term acne breakouts but no one with long term acne in the treated areas. Fraxel laser resurfacing has been a significant part of my practice along with other treatments for acne scarring such as punch grafts and microneedling.
