For best results, your feet should be clean and dry.✔️Move the unit in regular passes over the dry, dead skin, applying light to medium pressure. Continue with regular passes until the dead skin is removed and your feet feel silky soft. Stop if the skin becomes sore or inflamed.✔️Wipe or rinse feet to remove any excess dead skin and thoroughly dry feet. Finish by applying a foot balm or cream.✔️Use in successive sessions until your feet feel soft and are free from hard skin. Treatment length is different for each individual and depends on how much pressure is placed on your feet during daily activities, exercise, and the fit of your shoes.✔️The skin on your feet is 20 times thicker than on the rest of your body, so it helps to do 'something special' for the appearance of your feet. These Foot File is specially designed with a roller head to quickly and easily remove tough, thick skin by exfoliating the foot through a gentle and safe rotating action. And because it contains no sharp blades, so it’s safe to use as directed.
