We are bringing you a new series from Allure: The Science of Beauty, where we answer the tough questions about skincare, makeup, and more. If you love beauty and are curious about the science behind it, you're going to love this episode on sunscreen. Without protection from UV rays, every one of the greatest beauty innovations of the modern age — retinoids, AHAs, hyaluronic acid, lasers — is a big, old waste of time and money. It's fitting then that our debut episode is all about SPF. First, Michelle and Jenny have a frank talk with Shyla Raghav, vice president of climate at Conservation International, about how the state of our environment makes wearing sunscreen more crucial than ever before. Then, dermatologist Caroline Robinson shares everything you'd ever want to know about how to choose and use SPF, including the one place you're definitely not applying it — but should.
