Photoaging is not a new concept. This refers to what happens to the skin with too much exposure to the sun. When skin is exposed to excessive UV radiation from the sun, it can become leathery and wrinkled, as well as develop saggy areas and folds. Other results are freckles and those small wart-like bumps called keratosis. The most extreme result of photoaging is skin cancer. People with fair skin, light hair, and blue eyes are more susceptible to photoaging because their skin has less pigmentation, called melanin.
