Noodle & Boo's Play-Day Sunscreen - SPF 30 uses a special combination of gentle ingredients to create a natural defense against ultraviolet exposure by reflecting the sun's rays instead of absorbing them. Our lightweight, non-oily, water-resistant formula nurtures and moisturizes young skin while providing maximum protection. Fortified with aloe and vitamin E our sunscreen goes on effortlessly and dries quickly. Babies under six months should have little or no exposure to the sun, while children six months and older should not be outside without protection from the sun.
