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 vitamins in skin care.

You know vitamins as the micronutrients our body needs in order to function, but when applied topically, vitamins can have a profound effect on the health and appearance of our skin. In this episode, Michelle and Jenny learn about the man who first gave these micronutrients a name (he just so happens to have a very cool one himself) and tell the forgotten tale of the lost vitamins. Then, with the help of Dr. Frauke Neuser, PhD, Principal Scientist & Senior Director of Science Communications at Olay, Michelle and Jenny separate the facts from the fluff when it comes to vitamins and your skin. Yes, you should be using a vitamin C serum. And no, patting on vitamin D won't make your body produce more.
