The key to clearer skin is to double cleanse.

The double cleanse is the cleansing method Korean men and women use for clear skin. It involves washing your face in two steps, first by using an oil-based cleanser, followed by a foam cleanser. The first step melts away oil-based impurities such as waterproof make-up/bb, sebum, SPF, and pollutants while the second step cleanses sweat, bacteria and old skin cells.

Physical and chemical exfoliants remove dead skin cells from your face and can help reduce blackheads.
