You can use the Titania’s Corn and callous slicer on dry or wet skin. Nevertheless, it is often recommended to soak the hand or foot in a basin or sink or in the tub filled with warm soapy water for at least 15 to 20 minutes to soften the skin. It will make the removal of dead or excess skin with the callous scraper easier. • For extra dry skin and aching hands or feet, it is useful to add some Epsom or regular salt and some olive oil or essential or aromatic oil to soften and soothe the skin. • Next, wipe away the moisture, lightly hold the slicer, and slice the Corn and hard skin away. • Once you remove most of the hard skin, rinse your hand or foot in fresh warm water. In addition, pat it dry with a towel. • Now use the emery foot file lightly and gently to smooth the affected area without damaging the skin. • For a smooth, easy, and effective process of removing calluses and corns, Titania’s corn slicer is just the right product for you.
