Procedures used to diminish scars left by acne include the following:
Soft tissue fillers. Injecting soft tissue fillers, such as collagen or fat, under the skin and into indented scars can fill out or stretch the skin. This makes the scars less noticeable. Results are temporary, so you would need to repeat the injections periodically. Side effects include temporary swelling, redness and bruising.
Chemical peels. High-potency acid is applied to your skin to remove the top layer and minimize deeper scars.
Dermabrasion. This procedure is usually reserved for more severe scarring. It involves sanding (planing) the surface layer of skin with a rotating brush. This helps blend acne scars into the surrounding skin.
Laser resurfacing. This is a skin resurfacing procedure that uses a laser to improve the appearance of your skin.
Light therapy. Certain lasers, pulsed light sources and radiofrequency devices that don't injure the epidermis can be used to treat scars. These treatments heat the dermis and cause new skin to form. After several treatments, acne scars may appear less noticeable. This treatment has shorter recovery times than some other methods. But you may need to repeat the procedure more often and results are subtle.
Skin surgery. Using a minor procedure called punch excision, your doctor cuts out individual acne scars and repairs the hole at the scar site with stitches or a skin graft
