Collagen induction therapy, or microneedling, is a minimally invasive procedure that improves the health of your skin. A natural fibrous protein, collagen helps your skin stay smooth, supple, and firm. As you get older, your supply of collagen is reduced, which leads your skin to become thin and less elastic over time. Microneedling causes tiny skin wounds. These micro-injuries force your skin to generate new skin cell growth and increase collagen production. After a short recovery period, your complexion will appear healthier, firmer, and brighter.
