Hyaluronic acid is a powerful hydrating ingredient found naturally in the skin; however, the skin needs replenishment to maintain moisture levels. Our serum formulated with hyaluronic acid helps bind moisture to the skin’s surface, in turn smoothing skin and providing up to 24 hours of hydration. With three essential ceramides that strengthen and maintain your skin's natural protective barrier and vitamin B5 to soothe dry skin, CeraVe Hydrating Hyaluronic Acid Serum provides the skin with much-needed moisture and more.
