The causes of pustular acne are not yet completely clear, and are mainly related to changes in androgen levels, disease factors, poor living and eating habits, and drug factors. 1. Elevated levels of androgens: This causes sebum secretion to flourish, hair follicle sebaceous gland ducts to become narrower by keratinization, and excess sebum, if not discharged in a timely manner, will form sebaceous plugs; microorganisms such as Acinetobacter in the mouth of the hair follicle multiply in a relatively anaerobic environment, producing The enzymes break down the sebum into free fatty acids, stimulating the hair follicle wall and causing inflammation around the hair follicle sebaceous glands, which can eventually lead to the formation of pustular acne. 2, disease factors: such as polycystic ovary syndrome, Cushing’s syndrome, etc., can cause hormone level disorders in the body and abnormally high androgen levels, which can lead to the appearance of pustular acne. Acne can be triggered by a lack of nutrients in the body, long-term makeup and constipation; 4. Patients with pustular acne should try to avoid spicy, stimulating, greasy, high-fat foods; do not clean excessively, otherwise it will stimulate cells to secrete more oil, forming a vicious circle; avoid squeezing acne with your hands to avoid secondary infection, pus inflammation, leaving scars and affecting aesthetics; you should maintain a good mood and avoid depression.
