Track hormonal acne alongside your cycle
Hormonal acne has a schedule, but you can only see it if you track it. Acnera logs your period and predicts the next one, scores your skin, and lines the two up over time, so you can tell whether your breakouts follow your cycle, your stress, or something on your shelf.

Frequently asked questions
Can an app tell me if my acne is hormonal?
No app can diagnose it, but tracking can reveal the pattern dermatologists look for: breakouts that arrive at the same point in your cycle. Two or three cycles of data usually make the pattern clear.
When in my cycle does hormonal acne flare?
Most commonly in the week before your period. In a 2014 survey of women with period-related acne, 56% said it got worse in the week before their period.
What if I do not get periods?
You can still track stress, sleep, water, and your routine alongside your skin score. Those triggers can be just as revealing.
What helps hormonal acne?
Standard treatments like benzoyl peroxide and topical retinoids still help, and a dermatologist can prescribe hormonal options such as combined birth control pills or spironolactone.
