Abstract
Dermaroller is a novel therapeutic modality in dermatology. Through physical trauma from needle penetration, dermaroller induces a wound healing cascade with mild temporary damage to the epidermis. This allows for the enhancement in the absorption of topical therapies across the thick stratum corneum. Dermaroller has become increasingly utilized over the last several years as it is a relatively simple procedure that is cost effective, well tolerated and offers cosmetic and therapeutic benefits. The ability to treat localized areas of disease made it popular in acne scars, alopecia, striae, melasma, actinic keratoses. The procedure has few adverse sequelae compared to other therapies, is highly effective and a viable resurfacing option for color of skin.
