9 Acne Myths You Should Ignore

  

5. Stress Causes Acne

This one is partly true and partly untrue. Having a bad day won’t make your acne worse. However, there is a link between stress hormones (like glucocorticoids) and acne. The link isn’t well understood, but chronic stress, illness, and lack of sleep all increase glucocorticoids levels. High glucocorticoid levels can lead to changes in skin structure that worsen acne. So, while stress doesn’t cause acne, it can make existing acne worse if the stress lasts for a long time.
