What Does Hyaluronic Acid Do? Hyaluronic Acid occurs naturally in the deeper layers of our skin (the dermis). It helps to keep skin smooth and “plump” through its ability to hold up to 1,000 times its weight in water. Unfortunately, Hyaluronic Acid’s percentage tends to decrease with the passing time. This provokes wrinkles, atony and tissues relaxation. Gabor Selective ACIDE HYALURONIQUE has been creted in order to contrast all these slight blemishes. It is an extraordinary cosmetic line, made of pure and concentrate Hyaluroni Acid.
