Acne is a condition caused by over-production of oil. The pores secrete too much sebum(oil) which blocks the pores. Acne occurs primarily on the face, back, chest and shoulders.
Cleansing the face daily with an acne or oil-control cleansers is most effective. Follow with a toner and/or blemish treatment product to treat and prevent blemishes and irritation. Follow with an oil-free moisturizer.
