Acne vulgaris is the medical name for common acne —
the presence of blackheads, whiteheads, and other types of pimples on the skin.
The most common spots for breakouts are the face, chest, shoulders, and back.
Although mild acne may improve with over-the-counter treatments, more severe forms should be treated by a dermatologist.
Blackheads are comedones that are open at the surface of the skin. They are filled with excess oil and dead skin cells. It’s not dirt that causes the comedone to turn black. The black hue results from the irregular reflection of light coming from clogged hair follicles. Blackheads can frequently be treated with over-the-counter medications.
