Acne on face before menstruation

In daily life, every woman's daily life is different, and some minor problems will occur in certain parts of the body during menstruation. Some people will have acne on their face during menstruation. Because the androgen content or the ratio of androgen to estrogen during menstruation is relatively high, the activity of the sebaceous glands will be enhanced accordingly, which can easily cause acne on the face.

Question 1

Menstrual cycle: Every month or so, there is a cyclical change of autonomous thickening, blood vessel proliferation, glandular growth and secretion, and collapse and shedding of the endometrium accompanied by bleeding. This physiological cycle is called the menstrual cycle. The menstrual cycle is generally 28 to 35 days, from the beginning of this menstruation to the beginning of the next menstruation.

Question 2

Menstruation is controlled by the interaction between the hypothalamus, pituitary gland, and ovaries. The hypothalamus releases gonadotropin-releasing hormone, which acts on the pituitary gland. The pituitary gland releases gonadotropin and luteinizing hormone, which act on the ovaries, promoting the development of follicles and the secretion of estrogen.

Question 3

The follicles gradually mature and the estrogen content continues to rise, which in turn acts on the pituitary gland to form a peak in luteinizing hormone secretion. Under the action of luteinizing hormone, the follicle ovulates and forms a corpus luteum, which secretes a large amount of estrogen and progesterone. Under the action of progesterone, the endometrium proliferates, preparing for the implantation of the fertilized egg.

At this time, estrogen and progesterone also slowly reach their peak. The hypothalamus and pituitary gland feel that it is almost time to stop, and suddenly reduce the secretion of gonadotropin-releasing hormone, gonadotropin and luteinizing hormone. The corpus luteum shrinks, and the secretion of estrogen and progesterone decreases suddenly. Without the support of these two hormones, the endometrium loses its full strength, and the endometrium collapses, causing menstruation. "In short, during the entire menstrual cycle, the estrogen in the bodies of female compatriots experiences a process of slow increase and rapid decrease, which has a lot to do with the occurrence of acne. The "old friend" has come to report, and the next cycle is about to begin.
