Microneedling: a new approach for treating textural abnormalities and scars.

Microneedling is a minimally invasive procedure wherein small holes are created across the stratum corneum while keeping the epidermis partially intact. This produces microchannels that increase skin permeability and simultaneously stimulate growth factor release. Since the epidermis is retained, microneedling has less risk of infection, postinflammatory hyperpigmentation, and scarring compared to other resurfacing modalities. This is a review of the literature on microneedling in the treatment of textural abnormalities, specifically rhytides, scars, and striae.
