MDSolarSciences Mineral Creme SPF 50 ($30) – If you are responsible for packing for your whole family before embarking on vacation or if you prefer to use a mineral sunscreen, then here is the SPF for you! I use this on my kids and you can even put it on over make-up. The formula is safe enough to use on infants aged six months and up. You are not supposed to put sunscreen on infants younger than six months. Those little ones are advised to stay out of the sun completely. It’s extremely lightweight which makes it easy to apply if you’re trying to put it on a squirmy pre-schooler. The matte finish also doesn’t make it feel slick after it has been put on. An added bonus is that this contains Eco-cert zinc oxide.
