There aren’t any treatments available for purchase that have been clinically proven to treat acne scars. Some cosmetic treatments can benefit your acne, so if acne scarring is something you’re conscious of then you may wish to explore these.
Acne scars can be caused when you damage the skin by picking or squeezing spots (including using tools), so you should avoid this, however tempting you might find it. It can help to prevent acne from occurring in the first place.
