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
Common questions
Why do I get breakouts before my period?
Hormones moving oil production. In the premenstrual week, estrogen and progesterone fall while androgens (the male-pattern hormones everyone has) stay relatively higher - and androgens drive sebum: oil production rises, pores clog more easily, and inflammation follows. The signature: breakouts that cluster on the lower face - jawline, chin, around the mouth - and arrive on schedule, monthly. That pattern is common and it is genuinely cyclical acne, not coincidence. What works: the standard acne toolkit applied with timing - a consistent retinoid or benzoyl peroxide routine run all month (spot-treating the eruption is always late); gentle cleansing, not scrubbing; and keeping hands and phone off the jawline. For cyclical acne that keeps winning, the medical options are real: hormonal birth control smooths the hormone swing and is an approved acne treatment, and spironolactone (an androgen-blocker) is the dermatologist standby for adult female jawline acne. The flag worth naming: cyclical breakouts plus irregular periods plus excess hair growth is the PCOS pattern - worth a doctor visit on its own.
