Sunscreen alone is not enough to protect you completely. Since sun exposure also causes premature aging of the skin, be sure to wear a wide-brimmed hat to shade your face. Avoid the sun between 10 am and 3 pm when the sun's UV rays are the strongest. People with fair hair and skin are at the greatest risk of damage from the sun. However, even if you have dark skin or already have a tan, the sun can still damage your skin.
Children are also at very high risk for sun damage.
Studies have shown that sun exposure in childhood contributes to the development of moles, which increase the risk for skin cancer. Children should always wear sunblock and protective clothing. Don't use sunscreens on infants under 6 months of age.
