If all else fails, a cosmetic way (besides using make up primer) to improve the appearance of indented acne scars is to fill them in with silicone microdroplets. A few dermatologists and plastic surgeons offer this procedure to improve skin texture, though this is different from facial rejuvenation procedures, which usually have a minimal effect on acne scarring. Tiny silicone microdroplets are injected into individual indented scars to plump them up. Treated areas might scab and stay red for some time before fading. Silicone microdroplets do not make acne scars go away 100%, but compared to other acne scar treatments, they seem to have the best results.
