Skin problems

The skin is your body’s largest organ. Like other organs of the body, it has several important functions. It is a watertight barrier when you swim or take a shower. It also helps control your body temperature. It releases perspiration when you are hot and tells your brain to slow blood circulation when you are cold.

The skin also allows you to feel textures, such as rough and smooth, and alerts you when something is hot, cold, or painful. Your skin also protects you from germs.

Oil glands help the skin stay soft. During the teen years, too much oil can cause clogged pores, which leads to acne. Acne sores include whiteheads, blackheads, and pimples.

Other skin problems are caused by sun exposure. Exposure to the sun’s ultraviolet (UV) rays increases the risk of developing skin cancer. Sun exposure also damages the skin, causing wrinkles and premature aging.
