Zusammenfassung:	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. L'invention concerne des dispositifs préformés conçus pour l'apport d'améliorants destinés à la peau, aux cheveux ou aux ongles. Les dispositifs se présentent comme des bandes adhésives ou des masques à usage cosmétique ou thérapeutique et comprennent une feuille de gel solide unilamellaire qui a au moins une surface au moins partiellement recouverte avec une composition de revêtement discret qui comprend au moins un améliorant destiné à la peau, aux cheveux ou aux ongles. L'invention concerne aussi des procédés de fabrication et d'utilisation de ces dispositifs. La composition de revêtement permet une libération plus efficace d'améliorants destinés à la peau que les dispositifs existants et/ou permet une plus grande souplesse de formulation.
