The occurrence of sores is closely related to factors such as excessive sebum secretion, blockage of sebaceous glands in hair follicles, bacterial infection and inflammatory reaction. After entering adolescence, the level of androgen, especially testosterone, rises rapidly, which promotes the secretion of sebaceous glands.
And produce a large amount of sebum. At the same time, the abnormal keratinization of sebaceous gland ducts in hair follicles causes duct blockage, sebum excretion disorder and keratin plug, that is, micro-acne. Many microorganisms in hair follicles, especially propionibacterium acnes, proliferate in large numbers, and acne C.
Lipase produced by acid bacteria decomposes sebum to produce free fatty acids, and at the same time chemotaxis inflammatory cells and mediators, eventually inducing and aggravating inflammatory reactions.
