What causes adult female acne and makes it worse?
Family history of acne increases your risk of adult female acne, but diet, weight, and premenstrual flare do not. Severity is not related to any of these factors.
What they did
Cross-sectional case-control study of 112 women age 25 and older. Researchers clinically examined acne and asked women about their diet, family history of acne, weight, height, and whether their acne flares before their period.
What they found
Of the 56 women with acne, 58.9% experienced premenstrual flare and 51.8% had a family history of acne. Family history of acne was a significant risk factor (p≤0.001). Diet and BMI were not risk factors. The severity of acne was not related to premenstrual flares, diet, BMI, or family history.
What it means for you
If your mother or other family members had acne, you are more likely to develop it. What you eat and your weight do not appear to cause adult acne. Acne getting worse before your period does not mean your acne is more severe overall. The study was small with only 56 patients, and the control group was younger on average.
