Description:This teenage female patient presented to a clinical setting with a severe case of acne vulgaris.

You’ll note the coalescence of the cysts, or nodules indicating that in this case the inflammatory reaction is affecting more than merely the superficial layers of the skin. Acne manifests when there is a blockage of the hair follicles by a plug composed of a combination of sebum, dead skin cells, and bacteria, which causes ensuing inflammation, and rupture of the sebaceous, or oil gland surrounding the root of each hair shaft, thereby, spilling its contents into the surrounding tissues.
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.
