Sunscreen does not protect against melanoma, the most dangerous
form of skin cancer, according to researchers. Although the
lotions decrease the risk of sunburn, they do not block UVA
rays, which cause melanoma.
Researchers found that even sunscreens with the highest protection
factor of 35, applied in the correct amounts, were not effective
at filtering out the harmful rays. They say that people should
limit their sunbathing time and use clothing to block UVA
rays when sun is at its strongest.
