As we age, the amount of naturally occurring hyaluronic acid (HA) within the body decreases. Dermal fillers are gel-like substances, made up of hyaluronic acid, that are injected into the skin. Thanks to its ability to store moisture, hyaluronic acid is responsible for giving skin a plump, hydrated and youthful look. It can improve a number of common concerns such as restore lost volume, enhance facial contours, smooth lines and soften creases.
