ABSTRACT
The essential function of skin care cosmetics is to maintain beautiful and healthy skin. Skin care cosmetics, including creams, lotions, facial packs, cleansers, and astringents, have specific purposes and effects. The main purpose of a skin cleanser is to clean the skin surface by removing dirt to promote beautiful and healthy skin. Any dirt remaining on the skin surface or plugged in the pilosebaceous orifices is easily oxidized or degraded by oxygen and microorganisms, leading to skin trouble, including inflammation and acne vulgaris.
