Acne belongs to a common skin lesion manifestation of acne, which is related to androgen-induced sebum secretion, abnormal keratinization of follicular sebaceous gland ducts, and genetic factors.
1. Androgen-induced sebum secretion: Increased androgen levels or imbalance between androgen and estrogen levels after puberty can increase the size of sebaceous glands and sebum secretion, leading to a large amount of sebum secretion, which induces the formation of acne.
2. Abnormal keratinization of follicular sebaceous gland ducts: when the follicular sebaceous gland ducts are over-keratinized, the ducts will be narrowed and blocked, so that the shedding of epithelial cells and sebum can not be discharged, resulting in the formation of acne.
3. Genetic factors: the occurrence of acne has a certain degree of heredity, there is a phenomenon of family aggregation.
