The SkinPen Microneedling system is the only FDA-approved microneedling device available on the market and is only sold to licensed physicians. The SkinPen sets the industry standard for safety. The SkinPen microneedling system causes controlled micro-injuries to the skin to stimulate the body's natural wound-healing process. The micro-injuries trigger the release of cytokines and growth factors that lead to remodeling of collagen and elastin. It is clinically proven to improve the appearance of facial acne scars in patients 22 and older. It's a minimally-invasive procedure done in the office with little to no downtime.
