First, sebum secretion by sebaceous glands is a normal physiological phenomenon.

Second: if the sebaceous gland secretion function is hypersensitive, excessive sebum excretion, accumulation on the skin, and chronic skin inflammation at the accumulation place, it is called seborrheic dermatitis.

Third: improper care and abuse of skin care products hurt the water and oil balance function of the skin itself, resulting in disorder of water and oil metabolism of the skin. The pH value of healthy skin surface is about 5.2-5.5, which is not conducive to the growth of bacteria. Because of the invasion of chemical substances (cosmetics, skin care products, scalding agents), the increase of sebum secretion and the change of chemical composition, the inhibition effect of bacteria is reduced, so that the normal flora existing on the skin surface, such as Staphylococcus, pityriasis malassensis and Streptococcus, can multiply in large quantities, invade the skin and cause disease.
