Acne is not just a problem for teens. It can also affect many adults as well. Sometimes finding causes for outbreaks of acne will help in treating and controlling it. It is also important to understand how and why acne develops.
Acne occurs when secretions put out by the sebaceous glands become blocked.
These glands are located in hair follicles of the skin. They normally serve to lubricate the skin, but when these openings are plugged pimples, blackheads, whiteheads, or cysts develop. The clogged sebum appears as a bump called a comedone. When it stays closed it is considered a whitehead. If the bump opens the area exposed to the air sometimes turns black.
