Clinical studies show that using sunscreen regularly can impede the development of squamous cell carcinoma, a type of skin cancer. Less conclusive evidence suggests that sunscreen might also hamper basal cell carcinoma and melanoma, the deadliest form of skin cancer. But dermatologists encourage patients to make sunscreen a habit for another purpose: vanity. Sunscreen use may inhibit sun-induced changes to the skin’s pigment and texture. “If you look at your derrière when you come out of the shower, it’s obvious that the texture is smoother and the coloration is more uniform than your face, which gets regular sun exposure,” Dr. Katchen said. Look for sunscreens that contain zinc oxide, titanium dioxide or Mexoryl SX, ingredients that work against both the sun’s longer- and shorter-length rays.
