All About Acne
What is acne?
Acne, also known as acne vulgaris, is thought to be caused by multiple factors. Overproduction of a normal oil on the skin, increases under the influence of hormones. This, coupled with insufficient shedding of dead skin cells, plugs hair follicles. The plugged follicle can become inflamed and have increased growth of normal skin bacteria, Propionibacterium acnes.
