Sof'feet Callus Reducer is designed to reduce calluses and smooth away rough, hardened skin from the feet. The reducer works best if used on dry feet before shower or bath, and before applying any lotion or cream. The callus reducer is easy to use; gently rub callused areas to remove hardened skin. When the screen becomes filled with dry tissue, simply tap the reducer on a dry towel. After use, a daily application of the Sof'feet Softening Cream is recommended to help keep the feet soft and silky.
