The skin's main purpose is to protect the body against dirt, allergens, chemicals, oils and other irritants. When working in the lab, nail salon, fixing an engine or ceramic glazing, one's skin simply is unable to provide all the protection it needs. Kerodex acts like an invisible glove to guard the hands and forearms against harmful and irritating substances without affecting sense of touch, grip and dexterity. In addition, Kerodex's non-greasy formula won't clog pores.
