What are the most common causes of acne?
assistant
The most common causes of acne are bacteria, hormones, genetics, and stress. Bacteria can cause inflammation in the skin that leads to breakouts. Hormones can also play a role as they affect oil production and the way the body responds to certain foods. Genetics can also have an impact on how likely you are to develop acne. Stress can worsen existing acne by causing hormonal changes, which can lead to increased oil production.
