Between the moodiness, cramps, and bloating, the last thing a woman with PMS needs is to look in the mirror and see a big red pimple. But unfortunately, many women do.
Menstrual acne, a flare-up of blemishes every month that coincides with menstruation, is fairly common. According to a study published in the Archives of Dermatology, 63% of acne-prone women experience these premenstrual flares. They usually strike about seven to 10 days before the onset of a woman’s period and then subside as soon as bleeding begins.
Have you ever looked in the mirror and declared, “I should not have wrinkles
and pimples on the same face!” If so, you’re not alone. Acne: it isn’t just for
teenagers. In fact, many people are plagued by adult acne into their 30s, 40s,
and even 50s.
According to a survey done by dermatologists at the University of
In their 20s, 50.9% of women and 42.5% of men in their 20s reported
experiencing adult acne
In their 30s, 35.2% of women and 20.1% of men reported adult...
The average menstrual cycle is 28 days, and each of these days is different hormonally. “In the first half of a woman’s menstrual cycle, the predominant hormone is estrogen; in the second half, the main hormone is progesterone,” explains ob-gyn Elizabeth Gutrecht Lyster, MD. Lyster is part of Holtorf Medical Group in Orange County, Calif. “Then levels of both hormones fall to their lowest levels of the month as bleeding approaches,” she says.
Meanwhile, the male hormone testosterone (made in smaller amounts by women) stays at a constant level all month. “This means that before and during menstruation, testosterone is relatively higher than the female hormones,” Lyster says.
These behind-the-scenes hormonal shifts do all sorts of things to a woman’s skin. For one, the mid-cycle progesterone rise stimulates the production of sebum. Sebum is a thick, oily substance that acts as a natural skin lubricant.
“And as levels of progesterone increase, skin swells and pores are compressed shut,” explains dermatologist Audrey Kunin, MD, of DERMAdoctor.com. As a result, pores never looked so minimized. “But this tourniquet effect also causes sebum to build up beneath the skin’s surface.”
In addition, higher testosterone levels around menstruation further activate the sebaceous glands to make even more sebum.
Sebum yields different effects in different women. “For some, it produces a healthy glow; for others, it creates a chronic oil slick,” Kunin says. The oil provides food for the bacterium P. acnes. This bacterium causes increased breakouts and inflammation around the time of women's periods.
Unfortunately, you can’t change the relationship between acne and hormones. But there are some things you can do to make those breakouts less severe.
“Menstrual-related acne is not a matter of hygiene; it is an internal effect. However, women still need to take special care of their skin around their periods in order not to make things worse,” Lyster says.
