If we’ve said it once; we’ve said it 1,000 times: The best way to prevent aging skin is by wearing sunscreen every single day. But just because you apply it in the morning, doesn’t necessarily safeguard your skin from the sun’s damaging UV rays all day long. And, it has a lot more to do with reapplication.

A new study showed that a number of highly rated sunscreens actually didn’t stand up to the guidelines set forth by the American Academy of Dermatology (AAD). Researcher was performed on the top 1 percent of SPFs as rated on Amazon.com as of December 2015. Turns out that of the 65 sunscreens tested, 40 percent of them didn’t adhere to the AAD guidelines and most were due to a lack of water resistance.
According to the AAD, sunscreen should be water-resistant, provide protection against both UVA and UVB rays and have an SPF of 30 or higher. Not sure if your sunscreen measures up? If it doesn’t meet these three criteria, chances are it doesn’t. Make sure to only wear creams, sprays, gels and lotions that follow these guidelines. And, if you’re still uncertain, you can always ask your dermatologist to make a safe recommendation for you.
