From the website: "By forming hyaluronic acid and other ingredients directly into needles, we have made it possible to deliver beauty ingredients, which were previously difficult to penetrate, directly to the stratum corneum. This allows the moisturizing power of hyaluronic acid* to be fully realized, making fine lines caused by dryness less noticeable and giving firmness and elasticity to areas that tend to develop creases with age."
