Summer means slathering it on! But which sunscreen to choose? The Environmental Working Group—a nonprofit that conducts research on health and the environment—has released its annual list of approved sunscreens. From that list, mom.me selected the best 20 for babies and kids (as well as for mom and dad), to protect you against harmful UV rays. We chose these 20 because they contain zinc oxide, a natural, broad-spectrum ingredient that protects against UV rays and sits on top of the skin rather than being absorbed into it. We also left out sunscreens that include oxybenzone, which, according to the EWG, can disrupt hormones, and vitamin A, which can increase the development of skin tumors and lesions.
