Keratolytic lotion to soften keratoses, hyperkeratoses and calluses on hands and feet. A powerful and effective solution to soften the skin of calluses before they are removed. Keratolytic Application: We apply the keratolytic lotion only to problem areas. On well open cotton or pads. Wrap with transparent foil and let the product act for 10-15 minutes (depending on the case). After the 15 minutes have passed, remove the foil and cotton. With a pedicure spatula we take the product from the problem areas. Then we work with a scraper or grinder to remove the reinforcements. Finally, we apply peeling, rinse and then apply foot cream.
