Microneedling

Abstract

Microneedling (MN) is a minimally invasive procedure using fine needles to repetitively puncture the epidermis and/or dermis, generating microwounds in a controlled injury, leading to a wound-healing cascade and the release of growth factors, inducing new collagen and elastin and angiogenesis. MN is a simple technique procedure with relatively short downtime and minimal risk. It is widely used for various indications, including dyschromia, melasma, vitiligo, enlarged pores, and surgical scars. Current novel indications, such as transcutaneous medication delivery with many ingredients, involving cell therapy, have been developed. The combination modalities, such as chemical peeling, subcision, microdermabrasion, LED, and fractional laser resurfacing, have been introduced for better results.
