Abstract

Devices for applying film layers and/or active agent carriers to the skin are disclosed, including a liner layer having a release surface, a carrier layer for the film layer, a first adhesive between the carrier layer and the film layer, and a second adhesive between the liner layer and the opposite surface of the film layer and carrier layer. In this manner, the film layer is sandwiched between the liner layer and carrier layer, and the coefficients of adhesion of the two adhesives are selected so that upon separation of the liner layer and the carrier layer the film layer remains on the carrier layer, and upon application of the film layer to the skin, the film layer transfers from the carrier layer to the skin. The device preferably includes a hinge permanently connecting a peripheral edge of the carrier layer to the liner layer in order to facilitate this process, and in a preferred embodiment an active agent carrier is either substituted for or added to the film layer.
