Acne arriving at thirty is not adolescence running late. It has a different distribution, a different rhythm, and usually a different mechanism — which is why the routine that worked at sixteen so often does nothing now.
How adult acne differs from teenage acne
Teenage acne generally covers the whole face — forehead, nose, cheeks — and fades with age. Adult hormonal acne is classically described on the lower third: jaw, chin, neck. Treat that as a tendency rather than a rule, because many women have it more widely than the textbook picture. What is more reliable is the rhythm: it tends to flare in the week before a period.
The mechanism behind hormonal acne
Contrary to a widespread assumption, hormonal acne does not necessarily involve abnormally high androgens. Most often it reflects oil glands that are more sensitive to androgen levels that are themselves perfectly normal. That is why two women with comparable hormone panels can have completely different skin — and why a normal result does not mean the acne is not hormonal.
What actually helps
A suitable skincare routine is the base: non-comedogenic, and without the over-cleansing that irritates the skin and brings on more breakouts. Depending on the case and after medical advice, certain hormonal contraceptives or spironolactone may be proposed — spironolactone is effective in adult female acne but is prescribed off-label for it in France, must not be taken during pregnancy, and requires effective contraception throughout treatment. The link with diet — dairy, high-glycaemic foods — remains scientifically debated and varies enormously between individuals: something to observe in yourself rather than apply as a rule.
- Note whether your acne follows a cycle, flaring before your period — it is a strong pointer to a hormonal origin.
- Avoid over-cleansing, which usually worsens the inflammation rather than improving it.
- Give any change of routine or treatment two to three months before judging it.
- If the acne comes with increased hair growth or an irregular cycle, say so in consultation — the combination changes the direction.
