This section of the forum is dedicated to discussions on managing, treating, and correcting acne scarring. (Of note, Dr. Lam is focused principally on acne scarring rather than on managing the ongoing condition of acne, which a dermatologist would be better equipped to address.)
Hi,
Obviously, I would have to see it. If it is minor and does not require a formal scar revision, then most skin resurfacing methods do take some risk. Dermabrasion is possible if done with absolute control but the recovery can be extreme, sometimes lasting several months to a year either with the area looking too light, too dark, or too red. Fraxel may help if the scar is depressed but would not if it is relatively flat. If the scar is raised, then no laser or dermabrasion should be used, most likely 5-FU injections and non-penetrating ("vascular") lasers to bring down the scar or a formal scar revision. As you can see, this answer is almost impossible unless I see the scar itself.
Best,
SML
