Generally, there are no conscious symptoms and general discomfort. In some women, it is aggravated before menstruation. The occurrence of this disease is mostly related to the imbalance of female hormone metabolism, which is common in menstrual disorders, pregnancy, oral contraceptives and liver disease, while sun exposure and mental trauma are common triggers. Estrogen, progesterone and sunlight exposure can promote the metabolism of melanin and increase the amount of melanin contained in melanocytes in the basal layer of the epidermis, resulting in darkening of the skin color.
