Acne is a skin condition that causes spots and pimples,especially on the face, shoulders, back, neck, chest, and upper arms.
It is the most common skin condition in the United States (U.S.), affecting up to 50 millionAmericans yearly.
It commonly occurs during puberty, when the sebaceous glands activate, but it can occur at any age.
The glands produce oil and are stimulated by male hormones produced by the adrenal glands in both males and females.
At least 85 percent of people in the U.S. experience acne between the ages of 12 and 24 years.
Here are some facts about acne. More detail is in the main article.
Acne is a skin disease involving the oil glands at the base of hair follicles.
It affects 3 in every 4 people aged 11 to 30 years.
It is not dangerous, but it can leave skin scars.
Treatment depends on how severe and persistent it is.
Risk factors include genetics, the menstrual cycle, anxiety and stress, hot and humid climates, using oil-based makeup, and squeezing pimples.
Acne is a chronic, inflammatory skin disease that results in whiteheads, blackheads, pimples, cysts, and nodules. It is not dangerous, but it can leave skin scars.
Human skin has pores that connect to oil glands under the skin. Follicles connect the glands to the pores. Follicles are small sacs that produce and secrete liquid.
The glands produce an oily liquid called sebum. Sebum carries dead skin cells through the follicles to the surface of the skin. A small hair grows through the follicle out of the skin.
Pimples grow when these follicles get blocked, and oil builds up under the skin.
They tend to appear on the face, back, chest, shoulders, and neck.
Skin cells, sebum, and hair can clump together into a plug. This plug gets infected with bacteria, and swelling results.
