Pad and method of use for removing callus

A skin treatment system, comprising:

• an active agent for treatment of a callus;
• a first cushion layer having an inner surface, an outer surface, and an interior opening passing from the inner surface to the outer surface and defined by a continuous side wall, the opening configured for receiving the active agent;
• a second outer layer having an inner surface, a periphery, and a border extending inwardly of the periphery;
• a third intermediate layer impermeable to the active agent and configured to span the opening of the first cushion layer, the third intermediate layer affixed to the inner surface of the second outer layer such that a periphery of the third intermediate layer is spaced inwardly of the border of the second outer layer;
• and
• a selectively releasable adhesive material disposed on the inner surface of the second outer layer along the border for releasably securing the border of the second outer layer to the outer surface of the first cushion layer such that the second outer layer and the third intermediate layer cover the opening in the first cushion layer for sealing the opening and to prevent diffusion of the active agent from the cushion layer,
• wherein in an open position of the pad at least a portion of the second outer layer is spaced from the cushion layer such that the opening in the cushion layer is adapted to receive the active agent.

A method for treating the skin, the skin treatment method comprising the steps of:

• providing a pad comprising
• a first cushion layer having an inner surface, an outer surface, and an interior opening passing from the inner surface to the outer surface and defined by a continuous side wall;
• a second outer layer having an inner surface, a periphery, and a border extending inwardly of the periphery;
• a third intermediate layer impermeable to the active agent and configured to span the opening of the first cushion layer, the third intermediate layer affixed to the inner surface of the second outer layer such that a periphery of the third intermediate layer is spaced inwardly of the border of the second outer layer;
• and
• a selectively releasable adhesive material disposed on the inner surface of the second outer layer along the border for releasably securing the border of the second outer layer to the outer surface of the first cushion layer such that the second outer layer and the third intermediate layer cover the opening in the first cushion layer for sealing the opening and to prevent diffusion of the active agent from the cushion layer;
• securing the pad to the skin;
• opening the pad wherein in an open position of the pad at least a portion of the second outer layer is spaced from the cushion layer;
• depositing active agent for treatment of a callus in the opening in the cushion layer;
• and
• resealing the opening with the second outer layer and the third intermediate layer covering the opening.
