Background: Scar revision continues to be a challenge to any practicing cosmetic surgeon. Rejuvenation of existing scar without revision surgery reduces the psychological stress of the patient as well as the clinician. Nano fat grafting for scar rejuvenation has gained increasing popularity because of its relative safety and has become an increasingly popular alternative to dermal fillers due to its biocompatibility. The aim of this study is to determine the aesthetic outcome of nanofat injections in scars using a standardized and validated Patients Observer scar Assessment Scale (POSAS) and photographs.
