ABSTRACT:
The present invention relates to pre-formed devices for delivering benefit agents to the skin, hair or nails. The devices are patches or masks for cosmetic or therapeutic use and comprise a unilamellar, solid gel sheet having at least one surface at least partially coated with a discrete coating composition comprising at least one benefit agent for the skin, hair or nails. The invention also encompasses methods of producing and using such devices. The coating composition allows more efficient delivery of benefit agents to the skin than previously known devices and/or affords greater formulation flexibility.
