1.Acne, also known as acne, is a chronic inflammatory disease of the sebaceous gland unit of the hair follicle, which mainly occurs in adolescents and has a great psychological and social impact on adolescents, but it can often be naturally reduced or cured after puberty. The clinical manifestations are characterized by polymorphic skin lesions such as acne, papules, pustules, and nodules that tend to occur on the face.

After entering puberty, the level of androgens, especially testosterone, in the human body rises rapidly, which promotes the development of sebaceous glands and produces large amounts of sebum. At the same time, the abnormal keratinization of the sebaceous duct of the hair follicle causes the duct to be blocked, the sebum discharge is impaired, and the keratin plug is formed, that is, microcomedones. A variety of microorganisms in hair follicles, especially P. acnes, multiply, produce lipase enzymes that break down sebum to produce free fatty acids, and at the same time chemoattract inflammatory cells and mediators, and ultimately induce and aggravate the inflammatory response.
