why do we get pimples before periods

Between the moodiness, and, the last thing a woman with
needs is to look in the mirror and see a big red pimple. But unfortunately, many women do. Menstrual, a flare-up of blemishes every month that coincides with, is fairly common. According to a study published in the Archives of Dermatology, 63% of -prone women experience these premenstrual flares. They usually strike about seven to 10 days before the onset of a womanБs period and then subside as soon as bleeding begins. The average menstrual cycle is 28 days, and each of these days is different hormonally. БIn the first half of a womanБs menstrual cycle, the predominant hormone is ; in the second half, the main hormone is,Б explains ob-gyn Elizabeth Gutrecht Lyster, MD. Lyster is part of Holtorf Medical Group in Orange County, Calif.

БThen levels of both hormones fall to their lowest levels of the month as bleeding approaches,Б she says. Meanwhile, the male hormone (made in smaller amounts by women) stays at a constant level all month. БThis means that before and during, is relatively higher than the female hormones,Б Lyster says. These behind-the-scenes hormonal shifts do all sorts of things to a womanБs. 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. БAnd as levels of progesterone increase, skin swells and pores are compressed shut,Б explains dermatologist Audrey Kunin, MD, of DERMAdoctor. com. As a result, pores never looked so minimized.

БBut this tourniquet effect also causes sebum to build up beneath the skinБs surface. Б In addition, higher testosterone levels around further activate the sebaceous glands to make even more sebum. Sebum yields different effects in different women. БFor some, it produces a healthy glow; for others, it creates a chronic oil slick,Б 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 canБt change the relationship between acne and hormones. But there are some things you can do to make those breakouts less severe. БMenstrual-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,Б Lyster says. When your period comes to visit, it brings gifts: bloating, fatigue, and even the occasional freak-out. As if all that wasn't bad enough, though, many of us also contend with the seldom recognized, but very real, skin problems that pop up around that time of the month. The cause of the oily complexion and magnified pores that suddenly surface? It's actually our hormones. As our hormone levels shift from the more female oriented (like estrogen and progesterone) to the more male oriented (like testosterone) during our cycle, our oil glands go into overdrive, pores blow up, and cystic zits emerge.

But, in the same way weБve learned to prep for our periods by traveling with a stash of tampons and extra Motrin, we can also do a thing or two to quell our out-of-whack complexions. So, to get the scoop on just how to do this, we enlisted a few experts: Bethanee J. Schlosser, M. D. , Ph. D, an assistant professor in dermatology and obstetrics and gynecology at Northwestern University Feinberg School of Medicine; Sara Gottfried, a San Francisco-based ob-gyn and author of The Hormone Cure ; and Jessica Wu, a Los Angeles-based dermatologist and author of Feed Your Face. Ahead, get a week-by-week playbook of whatБs happening in our bodies, how it affects the appearance of our skin, and how to get it all under control. What's Happening Two Weeks Before Your Period As far as our skin is concerned, this is the week that should be considered the dreaded time of the month.

Between seven to 14 days before the start of our period, our levels of the sex hormone estradiol fall. Meanwhile, our testosterone remains at higher levels than those of the estradiol. This move to more male-prevalent hormones can lead to a more acne-prone complexion, particularly for those with skin that's more acneic in the first place. БItБs that shift of balance that can lead to increased activity of sebaceous glands and can manifest as oily skin, with an increase in developing acne lesions and oily hair and scalp as well,Б says Schlosser. This is the time when inflammation and zits can rear their ugly heads. [! ]
