How long do acne scars take to fade?
Scars from acne do not completely disappear on their own. With age, depressed acne scars frequently become more obvious due to collagen loss in the skin. But there are numerous procedures that can lessen the prominence of acne scars.
Within a few months, post-inflammatory redness or hyperpigmentation may naturally fade. For some people, it may take years for their condition to go gone without treatment.
