As skin ages, it looses hyaluronic acid. Hyaluronic acid is a sugar that naturally occurs in the skin. It absorbs water and gives the skin a youthful appearance. Hyaluronic acid loss causes deterioration of the thickness and structure of the skin, resulting in wrinkles. An injection treatment using hyaluronic acid based Restylane Skinboosters ™ increases hydration within the skin by absorbing water. This provides improved firmness, elasticity and smoothness.
