Using pumice, a natural silicate of volcanic origin, it gently removes hard skin and calluses, leaving it clean, smooth, and free of impurities. It's also ideal for exfoliating any other part of the body. Instructions for Use: Moisten the area to be treated with warm water, then gently rub the soap into the area, massaging gently until it forms a lather. Rinse after a few minutes. Apply a moisturizer after use.
