Great non-toxic sunscreen option!!
Size: 3 Fl Oz (Pack of 1)
Very happy with the ingredients in this sunscreen! I feel great about putting it on my skin. Just know it leaves a pretty noticeable white sheen when you wear it. I've noticed that a lot with natural sunscreens but it's worth it!

Very heave texture.
Size: 6 Fl Oz (Pack of 1)
The texture is very heavy and greasy, and it leaves a white cast that takes quite a while to disappear. It’s probably fine for the body during beach days, but not for daily use — especially not on the face.

Great product
I bought this SPF because it was on the EWG site. We used this for a southern carribbean cruise. I am very pleased! No sunburn but got a great tan. Easy to apply. Highly recommend!

Works well even in water.
Was able to apply and use for hours even in water without reapplying. Usually burn but not with this. It does go on white and very thick but runs in.
