Acne is the most common skin problem, and it affects more than 50 million Americans. Acne is a chronic inflammatory disease of pores that become clogged with an overproduction of skin oil, cellular debris, and bacteria.
Acne may be caused by hormonal changes, genetic factors, and certain medications, and can be exacerbated by stress, fried foods, and poor hygiene. The result is pimples, whiteheads, blackheads, pustules, or cysts. These blemishes typically occur on the face, neck, chest, and back.
If acne is severe enough, it can cause discoloration and scarring.
