Abstract
Skin contact devices are disclosed for treating the skin, including a film layer which is non-occlusive to the passage of water vapor, an occlusive layer adhesively affixed to the inner surface of the film layer, in which the occlusive layer does not permit water vapor to pass therethrough, and a series of vent slots extending through the occlusive layer so that water vapor contained within the occlusive layer can pass through these vents for subsequent passage through the film layer itself.
