Why do I get breakouts before my period?
Last updated September 3, 2026.
Hormones moving oil: the premenstrual estrogen-progesterone drop leaves androgens relatively higher, sebum rises, and pores clog - which is why the breakouts cluster on the jawline and chin, on schedule. What works: a consistent all-month routine (retinoid or benzoyl peroxide - spot-treating the eruption is always late), gentle cleansing, hands off the jawline. For acne that keeps winning: hormonal birth control is an approved acne treatment, and spironolactone is the dermatology standby for adult jawline acne. The flag: cyclical breakouts plus irregular periods plus excess hair growth is the PCOS pattern - worth a visit.
What to do
- Run the routine all month. Retinoids and benzoyl peroxide prevent; they do not rescue.
- Go gentle, not aggressive. Scrubbing inflames and worsens.
- Ask about hormonal options. Birth control and spironolactone both target the cause.
- Name the PCOS pattern. Breakouts plus irregular periods plus hair growth: get evaluated.
