Disclosed is a method for making an appliance adapted to transfer to, or associate with, the skin or tissue of a user, a composition, e.g., a moisturizing formulation. Because of possible interactions between the formulation and/or formulation ingredients and elastic polymers that may be employed to help give the appliance elastic qualities, the method comprises steps for providing an elastic layer or member and a shielding layer or member, with the shielding member interposed between the composition / formulation and the elastic member. The shielding layer and elastic layer may be integrally connected to one another, as in a film comprising two layers. Typically the shielding layer will be impermeable to the composition / formulation (e.g., by employing polymers, such as polypropylene comprising crystalline portions, such that the mass transport of the formulation through the shielding member is stopped or substantially impeded). |
