Sunscreen doesn’t cause melanoma; most melanoma cases are due to excess UV radiation from the sun

Melanoma is a type of skin cancer that starts in melanocytes, the cells in our skin that produce melanin. Melanin is responsible for skin color and pigmentation. UV radiation from the sun can cause DNA damage, which raises the risk of mutations that lead to cancer. Sunscreen helps reduce damage caused by UV radiation, but isn’t 100% protective. Dermatologists recommend that people take multiple measures to reduce UV exposure, such as wearing sun-protective clothing and sun avoidance, in addition to wearing sunscreen.
