Blackheads: Are caused by a buildup of

Blackheads are caused by a buildup of natural oils within the pores. They can be prevented by adopting an effective skincare routine and a healthy diet. If you get blackheads -- a type of acne that happens when dead skin cells and oil clog your pores -- you have plenty of methods to treat them. There are also ways to prevent new ones from forming. Blackheads , medically known as open comedones, are small, dark-colored bumps that appear on the skin's surface, primarily on the face, back, and shoulders. They form when a hair follicle becomes clogged with sebum (an oily substance produced by sebaceous glands), dead skin cells, and bacteria.
