Are chemical peel effective for acne scars?

Not really: Acne scars are usually too deep for chemical peels to have much effect. They are better treated with fraxel lasers or dermabrasion. For isolated scars, surgical revision or fillers may be appropriate.

Maybe: A series of chemical peels can be very effective for acne scars it they are not extensive or deep. It is best to consult with an experienced facial plastic surgeon or dermatologist who can discuss best options individualized to you.

Chemical peels: In short, yes. But that all depends on the depth of the scars, and the type/strength of chemical. Very deep scars are sometimes best treated by excising them first, then resurfacing. Extensive scarring may require repeat treatments, but sometimes a co2 laser or dermabrasion (not to be confused with microdermabrasion) is more effective. This depends greatly on the surgeon's skill.
