How the Menstrual Cycle Affects Acne

It seems to happen every month, like clockwork. Your skin appears to be clearing up nicely when suddenly it begins erupting in breakouts again, just around the time of your period. Could you be imagining it, or is premenstrual acne a real phenomenon?

Premenstrual Acne Symptoms

Premenstrual acne is a real phenomenon. Premenstrual acne, often dubbed "PMS acne," is a consistent flare-up or worsening of acne every month, coinciding with the menstrual cycle.

Some people find that their existing acne gets worse right before their periods. Others have relatively clear skin during the rest of the month, only breaking out a week or so before their periods.

Those PMS breakouts are different than your "typical" breakouts. They tend to be deep red and inflamed papules which rarely develop a white head. These breakouts appear mostly on the lower part of the face—cheeks, jawline, chin, and neck.

Premenstrual acne affects 50% to 80% of women who menstruate, according to various studies.

Causes of Acne Before Your Period

Your menstrual cycle can directly impact your skin and hormones are to blame. Just like hormones trigger acne development during puberty, hormones also play a big role in the breakouts you get right before your monthly cycle.

Hormones are also responsible for the acne that gets worse during pregnancy and menopause, too. Specifically, we're looking at testosterone.

Although we think of testosterone as a "male" hormone, women make it too, just in lower levels than men. Testosterone has been implicated as a factor in acne development because it triggers your sebaceous glands to produce more sebum (or oil).

For most, breakouts happen about a week to 10 days before the period begins. This is the time when estrogen is at its lowest. Testosterone levels stay fairly constant throughout the month, so as estrogen drops testosterone is relatively higher.

The hormone progesterone also plays a role in premenstrual and pregnancy acne. Progesterone levels rise during the second half of your cycle. It can make your skin more oily and cause pores to swell shut, trapping dirt and oil.

This creates a perfect storm for breakouts: your skin is more oily, and that oil can more easily become trapped in swollen pores. There may be other factors at work as well, and more studies are still being done on exactly how the menstrual cycle affects acne and the skin in general.


You don't have to simply endure these monthly breakouts. There are treatments that can help get them under control.

  • Birth control pills: Oral contraceptives have long been used to reduce acne breakouts, presumably because they help regulate hormonal fluctuations. However, not all birth control pills improve acne and some can make it worse. You need a birth control pill with a progesterone that's not particularly androgenic, like Yaz, which contains the progesterone drospirenone.
  • Benzoyl peroxide: This common acne medication works well on hormonal breakouts too. If your acne is mild, an OTC benzoyl peroxide may be all you need. Prescription benzoyl peroxide is an option if you need something stronger.
  • Topical retinoids: This is another prescription medication that works great for adult breakouts. They help keep those pores clear and can reduce fine lines and wrinkles too. Topical dapsone (Aczone) is a topical that is particularly helpful for inflammatory hormonal acne due to it's anti-inflammatory properties.
  • Spironolactone: If you're having trouble getting your acne under control, this hormonal regulator may be an option for you. Spironolactone is a prescription medication that you take orally.

Don't curse your skin this month. Instead, see your dermatologist and look forward to clear, healthy skin all month long.
