Hormonal Acne and Your Cycle

Breakouts that follow your cycle — especially around the jaw, chin, and cheeks — are a classic sign of hormonal acne. Here's why it happens and how cycle tracking helps you predict and manage it.

What causes it

In the late luteal phase, falling oestrogen means androgens (testosterone) become relatively more dominant. Androgens stimulate sebaceous glands to produce more sebum, increasing the likelihood of blocked pores and breakouts. Some women also notice acne flares around ovulation, when a brief LH surge elevates androgens temporarily. PCOS-related acne is driven by persistently elevated androgens throughout the cycle.

How to track it

Log breakout location, severity, and cycle day. Hormonal acne typically follows a consistent pattern — most women find breakouts appear on days 21–27 and resolve after their period starts. Tracking confirms the pattern, helps distinguish hormonal from dietary or stress-related acne, and provides evidence if you're seeking dermatological or hormonal treatment.

When to see a doctor

See a doctor or dermatologist if acne is severe, leaving scars, associated with excess body hair or irregular periods (possible PCOS), or not responding to standard topical treatments. Hormonal acne often responds to combined oral contraceptives, anti-androgen medications, or topical retinoids.
