Excellent
Size: 2.12 Ounce (Pack of 1)
So good I have re ordered for family. It goes on lite and gets clear almost immediately. Skin feels great with it on. Lightly moisturized and not greasy or sticky. Little to no scent.

Best I've tried in awhile
Size: 2.12 Ounce (Pack of 1)
I'm not allergic to it & didn't burn! Wasn't greasy, easy to apply. Worked great for face, neck, chest and arms. Wore for a week straight. Didn't clog pores or cause skin issues. Worked great as a sunscreen. Stayed solid enough in FL heat that TSA didn't confiscate. Double bonus

Great sunscreen
Size: 2.12 Ounce (Pack of 1)
This is the creamiest best sunscreen ever. It's not greasy and it feels like it's definitely moisturizing and goes on super smoothly.

Great all around sunscreen
Size: 2.12 Ounce (Pack of 1)
Love this product. I have dry skin and this is emollient but not greasy. Floats over my fave and feels just right while softening my fine lines. Light fragrance that’s not too much. I definitely recommend this for all skin types.

Itchy, red rash
Size: 2.12 Ounce (Pack of 1)
I suspect that they are lying about the ingredients in this product. I have never reacted to any skincare products except for chemical sunscreens. This product claims to be a mineral based sunscreen but I had a terrible reaction to it. I have an itchy, red rash all over my face and arms that's been taking days to improve. I can't help but wonder if they are not disclosing all of the components of this product. I will be returning this product and requesting a refund.
