Acne

Acne is one of the most obvious ways stress expresses itself. When some people are worried, they tend to touch their faces more frequently. This can spread germs and lead to acne formation. Several studies have also found that acne is linked to greater levels of stress. In one study, acne severity was assessed in 22 persons before and during an exam. Stress levels increased as a result of the exam and were linked to worse acne severity.

Another research of 94 youths discovered that higher stress levels were linked to worse acne, particularly in guys. These studies suggest a correlation but do not take other aspects into consideration. More study is needed to investigate the relationship between acne and stress. Aside from stress, other possible causes of acne include hormonal changes, germs, increased oil production, and clogged pores.
