For relief from painful corns on your feet, turn to Compound W. Compound W One Step Medicated Corn Remover has medicine built into the bandage, allowing for one-step application. The maximum strength formula contains the highest amount of salicylic acid available without a prescription. Compound W corn pads start working on contact, through the dual action of salicylic acid and hydrocolloid technology. Active ingredient salicylic acid is clinically proven; it removes corns effectively by penetrating deeply and breaking up the skin cells that form the corn. The hydrocolloid layer within the bandage reduces moisture loss, helping the skin stay moist while it heals. These are cushioned for all-day comfort, relieving pressure and protecting against rubbing and friction.
