An important thing to remember is that some natural oil Opuderm Premium Skin Care is necessary for your skin to retain moisture like it is supposed to. Over drying the skin causes it to produce more oil in an attempt to replace. Use oil-free makeup, cleanser and noncomedogenic moisturizers for taking care of oily skin. Noncomedogenic moisturizers are water-based moisturizers that prevent clogging of skin pores. Hot and humid weather causes our glands to produce more sebum and sweat.
