The skincare shelf is full, the routine is perfect, and the jawline still breaks out before every period.

If your acne ignores good skincare and keeps a stubborn pattern, the reason may be hormones, not your face wash. Hormonal acne is real, common, and recognisable once you know its signature. Here is how to tell whether hormones are behind your breakouts.

The signs your acne is hormonal

Hormonal acne has a fairly typical fingerprint:

  • Location: the jaw, chin, and lower face (and sometimes the neck), rather than the forehead
  • Timing: flares around your period, or with stress
  • Type: deep, tender bumps under the skin, not just surface whiteheads
  • Behaviour: it resists regular skincare and keeps coming back in the same spots

If several of these match, hormones are a strong suspect. If your acne is mostly surface bumps spread evenly, it may be more about products, oil, and bacteria — covered in adult acne: why it happens.

Why hormones cause acne

Certain hormones tell the skin's oil glands to produce more oil. More oil plus blocked pores and inflammation equals more spots. In women, this is closely tied to the menstrual cycle and to PCOS, where male-type hormones run higher. Stress hormones add to the effect, which is why busy, high-pressure phases often bring breakouts.

The PCOS connection

This is the important one. When jawline acne comes together with irregular periods, weight gain, or extra facial hair, it can point to PCOS — and the acne is just the most visible sign. Treating the skin alone, while missing the PCOS underneath, is why some acne never fully clears. Our PCOS symptoms guide explains the fuller picture.

What a doctor checks

A doctor diagnoses hormonal acne mainly from the pattern and history, then may check hormones, blood sugar, and thyroid — especially if other PCOS signs are present. Matching the skin to the hormones is what turns "endless breakouts" into a treatable, understood condition.

When good skincare isn't enough, the answer may not be on your skin at all.

Frequently asked questions

How do I know if my acne is hormonal?
Hormonal acne tends to sit on the jaw, chin, and lower face, flare around periods, appear as deep tender bumps, and resist regular skincare. It is more about hormones than hygiene.
What causes hormonal acne?
Shifts or imbalances in hormones increase oil production and inflammation in the skin. In women it is often linked to the menstrual cycle or PCOS; stress hormones also play a part.
Can a doctor test for hormonal acne?
A doctor diagnoses it mainly from the pattern and history, and may check hormones, blood sugar, and thyroid — especially if acne comes with irregular periods or extra facial hair.
