Abstract
The present invention relates to a topical delivery system effective in depositing a thin, tenacious and substantially continuous coating of a silk protein on skin by an aqueous emulsion mediated dissolution of protein from a substrate with subsequent transfer and deposition onto the skin. Coatings of silk protein on skin resist removal, thereby providing a protective barrier against chemically- and biochemically-induced skin damage. The treatment composition also provides a vehicle for administering an effective dose of an active agent to the skin surface.
