The Anatomy of Acne
- Skin is covered with tiny holes called hair follicles, or pores. Follicles contain oil glands, called sebaceous glands.
- These glands make oil, called sebum, that keeps your hair and skin moisturized.
- During puberty, hormones can cause the skin to make too much oil, and it can get stuck together with cells inside the pore, and with outside dirt or oil. This can cause a sticky plug in the pore, which becomes an acne a.k.a, pimple, zit, blackhead.
- Genetics plays a role, too. If your parent had acne as a teen, it's likely that you will, too.
