Stress: Being under stress can boost the production of male hormones called androgens. These hormones, which naturally occur in both men and women, stimulate oil production and can worsen acne.

Whether you’re 47 or 17, male or female, whether your breakouts are once a month or multiple times a week, the reason everyday, noncystic acne comes back and back is frustratingly simple: Human error. The minute a breakout clears, suddenly, you’re a person with clear skin—one who no longer needs to be quite so vigilant with their skincare routine.

Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
