    1. It occurs when glands (called sebaceous glands) in the follicles of the skin become overactive. These glands produce sebum, an oily substance that helps to stop the skin drying out. Someone with acne produces too much sebum, which forms a plug with dead skin cells and blocks the follicle.
    2. Gentle washing is important, but too much washing can irritate the whiteheads and blackheads, causing them to be more infected and making more pimples.
