# How common is acne that gets worse before your period?

Very common. About 3 in 4 women with acne get new spots before their period, usually 7 days or 2-3 days before menstruation starts.

 Early or limited evidence

400 women with acne in Kermanshah City

## 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%).

## What it means for you

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.
