Acne develops when pores in our skin become blocked with oil, dead skin cells, and sometimes bacteria. Hormonal changes, often during teenage years or menstruation, can trigger excess oil production, contributing to acne. Genetics play a role too. If your parents experienced acne, you might be more prone to it. Stress doesn’t directly cause acne, but it can worsen existing breakouts. Understanding the causes of acne helps us choose the most effective treatment options.
