Weak layer of human skin surface of the membrane, which regulates the state of the skin, protect skin health. This membrane secreted by the sebaceous glands secrete sebum and moisture from the composition of the balance between the amount of the two, determines the quality of this protective film, that is, the characteristics of our skin.
