Question:
Why do zits always form in the middle of the forehead?
Answer:
Acne, a red, irritating skin rash, that mostly affects children approaching puberty, usually appears in the oil-producing areas of the body. These include the face (forehead, nose, and chin), chest, and back. Hyperactive glands produce oil (sebum) at a faster than normal pace due to tweens’ rapid changes in hormone levels. Excessive oil clogs pores and creates acne, or pimples. Many times hair—which hangs down onto the forehead or sides of face—contains grease-like gels and styling products that contribute to acne.
