Exactly What Causes Hormonal Acne, and How to Clear It Up

When it comes to full-grown adults, hormonal acne refers specifically to period-related acne. "Men also have issues with hormonal acne, but in general, doctors do not call it hormonal acne," dermatologist Dr. Lady Dy said. "The height of a man's hormonal acne is in their teens — 13 years old to early 20s — when they're making the most testosterone. On average, after their mid-20s, men's testosterone levels slowly decrease for the rest of their life."

Dermatologist Dr. Craig Austin added that females typically experience hormonal acne during puberty and well into their 30s.
