The short explanation
In PCOS the ovaries often make more androgens, the male-type hormones that all women have in small amounts. Androgens make oil glands in the skin more active, which can block pores and lead to acne. Acne linked to hormones often appears on the jawline, chin and neck, can be deep and painful, and may flare before periods. Adult acne does not always mean PCOS, but it is a reasonable reason to check, especially if you also have irregular periods, extra facial or body hair or scalp hair thinning. If PCOS is part of the picture, treatment can target both the skin and the hormones.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A doctor may ask about your cycle, hair growth and weight and may suggest blood tests for hormones, and sometimes a scan.
- Treatment options for hormonal acne can include skin treatments and, for some women, hormonal treatments such as certain contraceptive pills, which a clinician may suggest.
- Avoid squeezing deep spots, as this can cause scarring and dark marks, which are common on brown skin.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your acne is linked to PCOS. That depends on your symptoms and tests.

Take these with you. You can add any of them to an appointment card.
