Abstract
Disclosed are compositions comprising crosslinked hyaluronic acid gels, preferably vinyl sulfone cross-linked hyaluronic acid known as hylan B gel, for use in topical cosmetic and dermatological formulations. The hylan B gel in these formulations provides prolonged delivery of incorporated substances to the surface of the skin, to provide a hydrated film on the surface of the skin, and to provide a substantive and compatible film on the skin.
