Hyaluronic acid (HA) is a sugar found naturally in our skin that holds water and helps keep it hydrated and plump. The HA within our bodies holds a thousand times its weight in water to not only retain all that moisture in our skin and joints, but also prevent all that moisture from evaporating into the air. Just like collagen and elastin, the amount of naturally-occurring hyaluronic acid in our bodies decreases as we get older.

Injectables like Versa+, JUVÉDERM, and Restylane use a gel form of hyaluronic acid to add volume to the dermal layer of the skin. With a few pricks of a needle, the gel plumps sunken areas, smooths fine lines, and decreases shadows—then slowly dissolves over the course of 12-18 months.
