Microneedling/skin needling leads the way in skin rejuvenation. When this treatment is safely delivered by a professional it carries no risk and minimal downtime. Microneedling works by encouraging your skin to make more collagen. The idea is that pinpricks from the procedure cause slight injury to the skin, the skin then responds by making new collagen-rich tissue. This new skin tissue is, in turn, more even in tone and texture.
