Acne Acne is a skin condition that can cause pimples, blackheads and cysts to develop on the face, chest, neck, shoulders or back. When dirt and oil accumulates in a hair follicle or oil gland, it clogs the pore. This is a perfect environment for bacteria to grow, irritating the surrounding skin and causing the area to break-out.
Most teenagers have problems with acne.
For some, the problem quickly clears up on its own but for most it lasts about 10 years. No one knows what causes acne, but certain things seem to aggravate it, including stress. Diet has not been proven as a factor, but some people are affected by certain foods. If you have a problem with acne, avoid oil-based cosmetics. Wash your face gently with a warm wash cloth using a mild soap and keep your hair clean.
