Come sunny days, overcast skies, or even wintery weather, UV rays do not discriminate. In fact, 80 percent of the sun’s rays can pass through clouds and reflect off surfaces like water, sand, snow, or pavement, which increases the amount of UV radiation you receive, according to the Skin Cancer Foundation. What’s more, UVA rays can also penetrate windows—i.e., the car, the office, your living room. So, exposed skin should be protected with a broad-spectrum (meaning, it shields against UVA and UVB rays) SPF 30 or higher year-round, not just in the summertime or at the beach or pool. And if you need another incentive: According to the Skin Cancer Foundation, daily sunscreen use can cut the incidence of melanoma in half. For your face, try Neutrogena Ultra Sheer Face Mist Sunscreen Broad Spectrum SPF 55. The invisible, lightweight formula dries to the touch and imparts an oil-free finish that won’t leave your complexion greasy, so it’s ideal for everyday use under makeup and super easy to reapply on the go.
