Acne is a term that is used to describe pimples, blackheads and whiteheads. Most teenagers get the type of acne called acne vulgaris. This can show up on the face, shoulders, chest,neck and back. Skin pores contain oil glands which naturally lubricate your skin and hair. But sometimes if a pore gets clogged beneath the skin with excess oil and bacteria, the dreaded acne is caused.
Whiteheads happen when a pore gets clogged, closes, and then bulges out. If a pore gets clogged but stays open, the top may darken and you've got a blackhead. A pimple happens when dead skin and bacteria work their way under live skin. This leads to a small infection that makes your skin look red.
