As skin ages, it loses its moisture because the body is producing less hyaluronic acid and collagen. At the same time, we lose volume from the deep fat compartments in our face and aging can reshape our facial bones. This shifting of tissue creates wrinkles, fine lines and hollows in various areas of the face. Facial injectable fillers work by replacing the volume and structure of lost fat, collagen and elastin. The result is restored plumpness, smoother features, volume where you want it and an immediate refreshed, youthful appearance.
