Pimples on the face are usually referred to as acne, and the main causes include increased androgen levels, propagation of Propionibacterium acnes, and keratinization of the follicular sebaceous gland ducts.
1. Increased androgen levels: Follicular sebaceous glands are independent endocrine tissues of the skin, which are mainly regulated by sex hormones. During puberty, the level of androgens in the body may increase, leading to the enlargement of sebaceous glands and increased sebum secretion. When sebum excretion is blocked and accumulates, acne is formed.
2. Propionibacterium acnes reproduction: Propionibacterium acnes is one of the common microorganisms in the skin. Sebum can provide oil and an anaerobic environment for microorganisms such as Propionibacterium acnes in the hair follicles, resulting in the reproduction of Propionibacterium acnes and stimulating proliferation of follicular keratinocytes and over-keratinization of follicular keratinocytes, which leads to blocked sebum drainage and then leads to the formation of acne.
3. Follicular sebaceous gland duct keratinization: When the skin follicles are subjected to long-term inflammatory stimulation or stimulation by microorganisms such as Propionibacterium acnes, proliferation and hyperkeratosis can occur, leading to obstruction of sebum excretion, and sebum and keratin plugs accumulate at the mouth of the hair follicle, then acne can be formed.
The appearance of acne on the face, the causes are more, it is recommended to timely seek medical treatment, under the guidance of professional doctors standardized treatment.
