Best Sunscreen and Reef Safe
Style: Spray (6 Oz)
I've been using this sunscreen for a couple of years now and this is the one! The lotion and the spray are both great, smell good and are reef friendly and organic. They are pricey but my skin appreciates the extra!

Great sunscreen that smells good too!
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1), Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
This stuff actually smells good and the scent doesn't smell like chemicals. It comes out clear which is perfect because I bought it for my little blonde headed, fair skinned 16 month old. It's nice to not have his hair looking all weird with white sunscreen spray. Overall, very pleased with it! Came just in time for our trip to the zoo the other day!

This worked well for the summer. No one experienced any burns while using it and reapplying. This also smells fantastic. Would definitely recommend and would buy again.
