Chin acne is not a gynecological inflammation. Chin acne generally refers to acne, which is related to abnormal androgen levels, overproduction of sebaceous glands, bacterial infections, abnormal keratinization of the cells around the hair follicles, and diet. 1. Abnormal androgen levels: When androgens are secreted in excess, they cause the sebaceous glands to produce more sebum. 2. Excessive secretion of sebaceous glands: When the sebum produced by the sebaceous glands mixes with shed epidermal tissue to form a substance that clogs the pores, acne is prone to flare-ups. 3. Bacterial infection: The overgrowth of Propionibacterium acnes facialis produces excessive free fatty acids, which irritate the hair follicles and the area around the follicles, making acne easy to form. 4. Abnormal keratinization of cells around the hair follicle: the opening of the hair follicle becomes smaller and blocked, resulting in sebum not being able to be discharged, and acne or micro-acne is easily formed. 5. Bad dietary habits: diets high in sugar, dairy products, etc. can cause acne or make acne worse. If you experience chin acne symptoms, please seek medical attention to avoid delay.
