Acne vulgaris, also known as acne vulgaris, may be associated with heredity, androgen-induced sebum secretion in large quantities, keratinization of follicular sebaceous gland ducts, propagation of Propionibacterium acnes, and immune-inflammatory response. Some patients are also affected by genetic, immune, endocrine, emotional and dietary factors.
1. Increased androgen levels or imbalance between male and female hormone levels after puberty may cause sebaceous glands to enlarge and sebum secretion to increase. This causes keratinization of the sebaceous gland ducts, resulting in acne on the skin surface.
2. Propionibacterium acnes reproduction can stimulate the follicular duct hyperkeratosis, so that sebum excretion is blocked, when sebum, keratin plugs, etc. accumulate in the mouth of the hair follicle, that is, the formation of pimples. Propionibacterium acnes can promote the production of inflammatory factors, causing an inflammatory response and a series of clinical manifestations from inflammatory papules to cystic damage.
3. Dietary stimuli: Sugar, strong alcohol, fat, chili peppers, fried food, etc. can induce acne.
4. Drug-induced: long-term oral or topical corticosteroids such as dexamethasone acetate, betamethasone, etc., can cause acne.
If you have acne on your cheeks, it is recommended that you consult a doctor in a timely manner to improve the relevant examinations under the guidance of the doctor to make a clear diagnosis and standardize the treatment in order to avoid delays in the condition.
