Acne scars can be more devastating than the acne itself. It is best to treat acne aggressively when it is noticed rather that to wait for scars to develop. The treatment for acne scars include chemical peeling, microneedling, microdermabrasion, surgical interventions like subcision, punch excision and punch grafting. Laser treatment with fractional lasers may be required if scarring is severe. Depressed scars may even be treated with fillers similar to wrinkles. What exactly you will need will depend on the nature of the scarring so the first step is to get the scars assessed and to discuss the possible treatments available.
