McGill study finds sunscreen use linked to false sense of security, rising skin cancer rates

Summary

McGill University researchers have identified a "sunscreen paradox" where rising sunscreen use correlates with increasing melanoma and skin cancer rates. The problem is that people use sunscreen as a "permission slip" to tan, applying inadequate amounts and spending excessive time in the sun, creating a false sense of security. Two studies — one examining Canadian Atlantic provinces and another analyzing the UK Biobank — found that individuals with higher sun exposure tend to use more sunscreen but not enough to provide adequate protection. Researchers emphasize that sunscreen is the least effective form of sun protection compared to protective clothing, rash guards, and sun avoidance.
