If you have unsightly and/or painful corns and calluses, look for Freezone Liquid Corn and Callus Remover. This product effectively removes corns and calluses in about two weeks thanks to its 17.6 percent salicylic acid formulation. For more stubborn corns or calluses, look for Maximum Strength Freezone Corn and Callus Remover. Simply brush the liquid on the affected area up to twice a day for two weeks and watch your corns and calluses disappear, as if by magic. It’s not really magic though. It’s just salicylic acid, which helps break down thick skin and increase moisture within the feet, causing corns, calluses and even warts to peel right off. In addition, collodoin produces a protective coating over the area in question and speeds healing. Do not use Freezeone on the face or other body parts or on moles, birthmarks or warts with hair growing out of them.
