Patented gel cushion provides immediate, all-day relief of pain. Dr. Scholl's Cushlin Gel Corn Cushions are made from Cushlin material, a technologically-advanced, soft polymer that is clinically proven to provide immediate, all-day relief from corn pain created by soft and hard corns. Its cushioning inner-surface molds to the shape of any foot and adheres to your skin without leaving a sticky residue. Its outer-surface is durable but smooth, much like your own skin, to prevent snags and runs to socks and hosiery.
