Acne is a common dermatological condition closely related to cosmetology. It is essentially a chronic inflammation of the sebaceous glands in the sebaceous areas of the skin. According to epidemiological findings, 90 percent of people suffer from acne during their young adulthood. The causes of this disease are complex and are related to androgen levels, overproduction of sebum by active sebaceous glands, infection by Propionibacterium acnes in the follicular sebaceous glands, abnormal keratinization of the follicular sebaceous ducts, genetics, climate, diet and cosmetics, and many other factors. The focus of many factors may vary from person to person, so clinical manifestations, lesion types, lesion distribution, and severity may differ. Therefore, the clinical manifestations, lesion types, lesion distribution, and severity may be different. We need to remind you that the first thing you need to do to treat acne is to have a light diet, eat as little alcohol, spicy, fried, baked and sweet foods as possible, have a regular lifestyle, and do not stay up late. Here is a special point to make. Some women suffer from “hyperandrogenic acne”. These patients not only have large pores on the face, rough and dull skin, but also have heavy acne lesions, such as nodules, cysts, abscesses, and scarring, and the lesions increase during menstruation. It can also be accompanied by hairy extremities, beard, hair loss, and menstrual cycle disorders. For hyperandrogenic acne, we must first look for the cause of hyperandrogenism, and then anti-androgen treatment.
