Sunscreen is a type of cream or lotion that you put on your skin to protect it from the sun's harmful rays. You use it when you go outside on a sunny day, especially if you will be in the sun for a long time. Sunscreen can help prevent sunburn, skin aging and skin cancer. It is important to choose a sunscreen with a high SPF (Sun Protection Factor) and to apply it evenly on all exposed skin.
