Acne, or acne vulgaris, is a common long-term skin condition caused when dead skin cells and oil clog hair follicles. It usually shows up as blackheads, whiteheads, pimples, oily skin, or even scarring. Areas with more oil glands—like the face, chest, and back—are most affected.
This condition can impact mental health. As the article says, it can lead to “lack of confidence, anxiety, reduced self-esteem, and, in extreme cases, depression.”
Genetics play the biggest role, responsible for about 80% of cases. Diet and smoking may play a part, but there’s no clear link. Cleanliness and sun exposure aren’t known to affect acne.
Hormones, especially androgens, also play a key role by increasing oil (sebum) production. Another factor is the overgrowth of a skin bacterium called *Cutibacterium acnes*.
While acne can be frustrating, understanding its causes helps in finding better ways to manage it.
