When it comes to sunscreen, the most important number is 365

My dermatologist asking me if I wear sunscreen every day used to be the equivalent of my dentist inquiring about my flossing habit (or lack thereof). These days I slather moisturizer sunscreen all over my face even on the rainiest days. Of course, reaching for a bottle of SPF 50 is undeniably important when the sun is shining, but the number you really need to focus on is 365.

Don’t let dark skies fool you. According to the American Academy of Dermatology, UV rays can cause harm year-round; on cloudy days, up to 80 percent can penetrate your skin. Even if you’ve escaped the spring showers in your apartment, major damage can still be done through the windows. I get it, though, sticky sunscreen isn’t something I want to put on my face every day. Luckily, a clean-feeling moisturizer with SPF does the trick.

Moisturizer sunscreen fights dryness and cracking while protecting against skin cancer and sun-related aging. Once you see how much your complexion loves your new routine, there’s a strong chance you’ll become just as obsessed as I am. SPF 365, for the win.
