Blackheads in medicine refers to open pimples, which are generally related to endocrine factors, abnormal keratinization of follicular sebaceous gland ducts, as well as heredity, microbial infection and other factors.
1. Endocrine factors: Increased levels of androgens in the body will promote the secretion of sebaceous glands, resulting in a large amount of oil production, causing open pimples on the facial skin.
2. Abnormal keratinization of follicular sebaceous gland ducts: Abnormal keratinization of follicular sebaceous gland ducts will lead to narrowing of the ducts, so that the cells and sebum shed by the follicle wall can not be discharged in time, which may lead to the appearance of open pimples on the face.
3. Genetic factors: open acne has a certain genetic predisposition, if both parents suffer from open acne, the chance of their children suffering from the disease will also increase.
4. Microbial infections: Open pimples can be triggered when the face is invaded by bacteria such as Propionibacterium acnes, which leads to localized infections.
There are many causes of open pimples on the facial skin, and patients are advised to seek medical examination to identify the causes.
