Since the procedure stimulates a person’s own collagen production, how long the results last depend on the individual. While results appear over two to three months, results may improve over the following three to six months and can last up to a year or more. The treatment produces new collagen on the inside, but the individual’s natural aging process will dictate how long that translates into visible results on the outside. Future touch-up treatments can help provide more control over the aging process, which varies by individual.
