Acne is a common condition which occurs when hair follicles in the skin become clogged by a combination of sebum – an oily substance produced by the skin – dirt, and dead skin cells. Acne can include blackheads, whiteheads, pimples, and cysts. It usually appears on the face and neck but it can also affect shoulders, back, and arms. Acne usually starts in the teenage years as hormonal changes cause the sebaceous glands to produce more sebum. It can continue into adulthood with stress, monthly hormonal changes, certain medications or the use of oil-based products all contributing to breakouts. Acne is not caused by poor hygiene or by eating chocolate or greasy foods, but genetics do play a role, so if either of your parents had acne chances are you will too. Acne can sometimes clear up on its own, but without treatment it can become severe and lead to permanent scarring so it’s best to get it under control early.
