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.
