What hormonal acne is

Hormonal acne is acne that rises and falls with your hormones, mainly androgens such as testosterone. It means the oil glands in your skin react to hormone levels, so breakouts follow puberty, your menstrual cycle, pregnancy or menopause. The cause of hormonal acne is extra sebum: androgens push the glands to make more oil, oil and dead skin cells block the hair follicle, bacteria grow in the plug and inflammation follows.

Doctors file it under ordinary acne (acne vulgaris); in some people the hormonal part is just more prominent.

Common Causes

The common causes of hormonal acne are androgens, the life stages that shift them, a few medical conditions and some everyday factors.

Androgens

Androgens are hormones such as testosterone. Women make them too, in smaller amounts than men. They drive the oil glands, so higher levels mean more sebum and more blocked pores, and in PCOS they can also cause extra hair on the face or body.

Life Stages

Hormone levels change in puberty, around periods, in pregnancy and at menopause, and acne can start or flare at each of those points. It is most common in teenagers, but it can last into middle age.

Medical Conditions

Polycystic ovary syndrome (PCOS, now also called polyendocrine metabolic ovary syndrome or PMOS) is a hormonal disorder with high androgen levels. Its signs include irregular or missed periods, extra hair on the face or body, oily skin and severe acne that may be hard to treat.

Lifestyle Factors

Stress, birth control pills and some medicines, such as steroids, testosterone and estrogen, can trigger breakouts, and so can some hormone IUDs. Greasy cosmetics and hair products, heavy sweating and humidity add to it. Research does not show that chocolate, nuts or greasy foods cause acne.

Who gets hormonal acne

Hormonal acne can start in puberty and carry on into adult life.

Who gets hormonal acne
GroupWhat the research shows
Teens and young adultsAcne affects up to 85% of people aged 12 to 24. Androgens rising in puberty play a central role.
Adult women, 25 and olderIn one clinic study of 208 women, acne sat on the cheeks in 87% and around the mouth in 81.7%. It flared before periods in 72.6% and with stress in 53.8%, and 48.1% had PCOS. These were clinic patients, not a random sample.
Women over 33In a survey of 400 women and girls aged 12 to 52, 44% had premenstrual flares, and women over 33 had them more often than women aged 20 to 33.

Jawline breakouts are a known hormonal sign, but in the clinic study the cheeks and the skin around the mouth were the most common places, so location alone does not prove a cause. Not sure which pattern yours follows? A photo analysis of your skin can point to the likely cause.

Treatment Options

Treatment for hormonal acne is regular acne care plus, for some women, medicine that works on hormones.

Topical Treatments
Benzoyl peroxide and salicylic acid are sold over the counter. Retinoids such as adapalene and tretinoin reduce oil and inflammation and prevent new spots.
Oral Medications
For acne driven by hormones, ask your doctor about spironolactone or the combined pill. The pill helps some women but can make acne worse in others.

Treatment follows the same hormones, from retinoids up to spironolactone; this guide to hormonal acne treatment walks through each step.

Spearmint, zinc and inositol come up in every forum thread, and the trials behind supplements for hormonal acne are small, so read the grades first. Each guide answers one question, so you can skip what doesn't fit your skin.

When to see a doctor

Professional Guidance

Professional guidance is help from a family doctor, gynecologist or dermatologist when self-care is not enough. See one if you notice:

  • Irregular or missed periods, or extra hair on the face or body (both are PCOS signs)
  • Spots that are deep, painful or leaving scars
  • Acne that keeps getting worse, or is no better after several months of self-care
  • Acne that affects your mood or how you feel about yourself

Reader questions

How can I tell if my acne is hormonal?

Look at where and when. Breakouts on your chin, jaw and lower face that flare in the week before your period lean hormonal. Run the pattern check above, or get a read from a photo of your face.

How to tell if acne is hormonal or bacterial?

It's usually both. Every pimple involves oil, a blocked pore, bacteria and inflammation. Hormones set off the extra oil and bacteria then feed the redness. So the better question is what drives the oil, and timing with your cycle is the best clue.

Does estrogen cause acne?

It can for some people. Estrogen is on the list of medicines that can trigger acne. Birth control pills are mixed too: they help some women and make acne worse in others. If a new pill or hormone treatment lines up with new breakouts, tell your doctor.

What should I avoid if I have hormonal acne?

Picking and squeezing, because it scars. Also scrubbing, greasy makeup and hair products, sleeping in makeup, and tight headbands or caps. You can keep the chocolate: research hasn't shown that it causes acne.

What do stress pimples look like?

Like any other pimple. Stress is a common trigger, and more than half of the women in one clinic study said it made their acne worse, but it doesn't create a special kind of spot.
