A callus is a buildup of dead skin cells formed from constant rubbing and friction. Exfoliating regularly is key to preventing them. But what do you do once you’ve got one? Most of us will reach for the pumice stone or callus scraper and start working away at it. Step away from the scraper! Trying to remove calluses when skin is dry can cause abrasions and damage. Start with a bath, shower or foot soak in warm water with a teaspoon of Epsom salts, then, massage a foot scrub onto the calloused area. For more stubborn calluses, use a pumice brush or foot file.
