Wear Sunscreen and Look Younger
Dermatologists have been telling patients for years that using sunscreen regularly can protect skin against aging. Now there’s research to back that up.In a study published in the Annals of Internal Medicine, researchers showed that people instructed to apply sunscreen every day showed 24% less skin aging, as measured by lines and coarseness of the skin, than those told to use the cream as they usually do.
Rules implemented last year by the U.S. Food and Drug Administration say that only sunscreen that are broad-spectrum—protecting against both UVA and UVB rays—and that have an SPF of 15 or higher can claim to reduce the risk of early skin aging and skin cancer. Both types of rays are implicated in photoaging and cancer. Products that don’t protect against both types of rays or that have an SPF between 2 and 14 can claim only to help prevent sunburn.
