Clean the skin 1 week in advance to repel the physiological acne reported in the past month

From menarche to before menopause, women's hormone levels are always changing periodically, which can cause menstruation and also affect the state of the skin. During the period from ovulation to menstruation, the ratio of androgen to estrogen levels rises, leading to increased sebaceous gland activity and secretion of more oil; on the 15th-20th day of the menstrual cycle, the hair follicle sebaceous gland duct is the narrowest, prone to oil blockage ; Higher levels of androgens will also thicken the stratum corneum, causing rough skin and even blocking the opening of the hair follicles. These are all factors that cause "physiological acne". So first of all, you must carefully observe the changes in your skin condition throughout the menstrual cycle, and take corresponding measures before the next menstrual cycle arrives.
