Abstract: Background: Many therapeutic modalities have been developed to attempt cosmetic correction of acne scarring, including ablative laser resurfacing, chemical peeling, dermabrasion, punch techniques, subcuticular incision (subcision), injection of dermal fillers, and most recently fractional photothermolysis. This article discussed specifically on the treatment of subcision. Subcision (subcutaneous incisionless surgery) is a surgical intervention that is used to treat a variety of skin depressions, including atrophic acne scars, depressed scars, wrinkles, striae, and cellulite, using a Nokor needle or hypodermic needle.
