What Causes Acne

According to the American Academy of Dermatology, acne develops when hormonal shifts (like the kind that occur during puberty, and in women, before a menstrual cycle and sometimes prior to menopause) cause an overproduction of oil and cells inside a skin follicle. Together, they form a kind of biological traffic jam that plugs the opening of the pore and causes the follicle beneath to swell.
This allows for the overgrowth of bacteria found normally on skin — Propionibacterium acnes (P. acnes) — producing irritating chemical substances, which further fuel the inflammation. The end result is acne.
“It can be characterized by anything from whiteheads and blackheads, to tiny hard pimples you barely see, to pus-filled nodules, even fluid-filled cysts with roots deep in the skin,” says Sumayah Jamal, MD, PhD, an assistant professor of dermatology and microbiology at the NYU Medical Center in New York City.http://hltcenter.com
