They represent circular seals of the keratin layer of the epidermis of the skin, which appear after a continuous friction or pressure. Women experience calluses more frequently than men, because they wear narrow and uncomfortable shoes, shoes with high heels. The pressure and the friction stimulate the creation of additional keratin, so that the skin can handle the experienced stress. As a result, the upper layer of the skin becomes rough and hard.
To reduce the callus, we recommend to apply a specialized cream with keratolytic or exfoliating properties.
