What they did
Dermatologists assessed acne in 400 women using a checklist to record when new spots appeared during their menstrual cycle.
What they found
New acne spots occurred in 79.5% of women during their menstrual cycle. In 75% of women, new spots appeared before menstruation, mostly 7 days before (28%) or 2-3 days before (18.3%).

Acne that worsens with your cycle is very common. The main limit is this study only looked at women with acne in one city in Iran, so results may not apply everywhere.
