6 Reasons Why Sunscreen Is Essential, According to Dermatologists

Melanoma is no joke, and it's the number one reason why dermatologists — and all doctors, for that matter, insist on daily sunscreen application.

"SPF protects our skin against the harmful UV radiation rays from the sun. We know that UV radiation leads to skin cancer, so protecting ourselves is key," says Dr. Deanne Robinson, a board-certified dermatologist based in Westport, Conn. "Using a broad-spectrum with an SPF of 30 of above and reapplying every two hours — or after water and sports — is key."
