The amount of skin care options available to slather on your face is dizzying. There are lotions, serums, masks, oils, and acids as well as stem cells, snail slime, charcoal, and even diamonds. And with complicated ingredient lists, it can feel like you need a chemistry degree to purchase a basic moisturizer.

Only drugs approved by the Food and Drug Administration (FDA) are allowed to alter the structure or function of your skin.
“Anything that’s regulated as a drug is going to have the most evidence behind it,” says Michelle Wong, a PhD chemist and science educator who moonlights as the beauty blogger Lab Muffin.
