How to Choose the Right Face Sunscreen

“First, you should choose an SPF 30 or higher that has broad-spectrum coverage, meaning that it protects from both UVA and UVB rays,” explains Dr. Mack. “When using a chemical sunscreen, it should be applied at least 15 to 20 minutes before sun exposure on bare skin. Physical sunscreens, however, may be applied immediately before sun exposure because they don’t take time to work.”

A couple sunscreens we love to wear under makeup include the CeraVe 100% Mineral Sunscreen SPF 30 and the Lancôme UV Expert Aquagel Sunscreen.

How Much Sunscreen Should You Use? 

According to Dr. Mack, most people aren’t using enough sunscreen. “To truly achieve the SPF on the packaging of the bottle, you should use at least two milligrams of sunscreen per square centimeter of skin,” she says. “This translates to a nickel-size dollop to the face alone. That means that most adults need one ounce — or a full shot glass — to cover their entire body.”
