I have post inflammatory erythema from healed acne (red marks). what will best treat this? chemical peels, ivl, microdermabrasion, other? thank you

How long?: How long has it been since acne areas have healed? If within 6 months, time may be all you need. If red areas persist certainly IPL can be beneficial to reduce redness. Laser resurfacing, peels, dermabrasion help for texture irregularities and smooth ance scars and lines. They would likely not be my first choice if you just have redness though. Hope that helps.
