Acne and Hormonal Changes
Hormones are one of the biggest reasons acne can appear, disappear, or suddenly become worse—especially during puberty, menstrual cycles, pregnancy, or other periods of hormonal change.
How hormones trigger acne
Hormones called androgens can stimulate your sebaceous glands to produce more oil. More oil, combined with dead skin cells, can clog hair follicles. This creates an environment where inflammation and acne develop.
Hormonal changes → more oil → clogged pores → inflammation → breakouts
Common times hormonal acne appears
- Puberty: Rising androgen levels can dramatically increase oil production.
- Around your period: Some people notice breakouts in the days before menstruation.
- Pregnancy: Hormonal fluctuations can change acne in either direction.
- Starting or stopping hormonal contraception: Changes in hormone levels can sometimes trigger or improve acne.
- Perimenopause: Shifting hormones can cause acne to return or worsen in adulthood.
Where hormonal acne tends to appear
Hormonal acne is often concentrated around the:
Chin → jawline → lower cheeks
It may appear as deep, tender pimples or cysts rather than just small surface-level bumps, and it may repeatedly flare at predictable times.
What can help
For mild acne, ingredients such as benzoyl peroxide, salicylic acid, and topical retinoids can be effective. If breakouts are persistent or strongly linked to hormonal changes, a dermatologist can discuss prescription options, including hormonal treatments when appropriate.
One important point: not every breakout on the chin or jawline is hormonal acne. Location alone can’t establish the cause—the timing, appearance, and pattern matter too.
