A non-sterile adhesive dressing intended for protection of corns or calluses (hardened areas of skin on the feet or toes) or unopened blisters, and to maintain a moist environment to allow the lesion to heal. It consists of a pad of material (e.g., hydrocolloid) and may be impregnated with an acid (e.g., salicylic) which acts as a keratolytic agent to facilitate the removal of dead skin. It may be supplied with another dressing (e.g., ring) to provide additional protection/cushioning around the lesion. It is normally available [non-prescription] over-the-counter (OTC). This is a single-use device.
