Cetaphil Oily Skin Cleanser cleanses oily, combination or blemished skin. Its gentle foaming action removes oil, dirt, skin debris and makeup without leaving your skin dry and without tightness. It does not clog pores and can be used in conjunction with acne medication. Higher than normal levels of sebum production is the reason why skin appears oily. Used twice daily for two weeks on people with moderately oily skin, Cetaphil Oily Skin Cleanser reduced sebum levels by up to 60% without over drying the skin. Suitable for oily, and combination skin.
