A woman's physiological cycle is mainly divided into four periods: menstrual period, follicular phase (1 week before ovulation), pre-luteal phase (1 week after ovulation) and late luteal phase (1 week before menstruation). To understand what stage your skin is in, just measure your basal body temperature.

Female menstrual cycle

Menstrual period week 1

A low-key period for the skin. The skin becomes dry, metabolism slows down, and the protection against the external environment is reduced.

The secretion of the two hormones decreases rapidly, and physiological bleeding will also cause physical exhaustion and nutrient loss. The skin becomes sensitive and dry. Menstrual pain, lower body temperature.

Follicular phase week 2 (one week before ovulation)

Skin in optimal condition. The skin enters a state of optimal balance.

This is the period when filter cell hormone secretion is most active. The blood flow to the skin increases, metabolism is vigorous, and the skin becomes delicate and full of feminine charm.

Pre-luteal phase 3rd week (1 week after ovulation)

The skin's adjustment period. The skin's balance gradually changes.

Progesterone continues to increase and estrogen fluctuates. Blood flow increases, body temperature rises, and the body enters a period of physiological adjustment. Progesterone can cause mental instability and make people prone to tension and anxiety.

Late luteal phase, 4th week (1 week before menstruation)

Skin discomfort occurs regularly. Sebum secretion is vigorous and melanin activity is enhanced, making skin problems such as acne, dark spots, and seborrheic dermatitis more likely to occur.

Peak period of progesterone secretion. The activity of sebum and pigment increases, and the skin temperature rises, which can easily cause congestion and flushing. In addition to skin problems, "premenstrual syndrome" symptoms such as headaches, abdominal pain, and fatigue may also occur.

How to calculate menstrual cycle

A woman's ovulation date is generally about 14 days before the next menstrual period. Starting from the first day of the next menstrual period, counting down 14 days or subtracting 14 days is the ovulation day. The ovulation day and the 5 days before and 4 days after the ovulation day are called the ovulation period. For example, a woman's menstrual cycle is 28 days, and the first day of this menstruation is December 2nd. Then the next menstruation will be on December 30th (December 2nd plus 28 days). Subtract 14 days from December 30th, and December 16th is the ovulation day. The ovulation day and the 5 days before and 4 days after it, that is, December 11-20, is the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe period.
