Good product, a little pricey though
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Pretty good consistency and easy to be applied evenly. Much better than the sunscreen products I used before

Perfect sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
I love the roll on sunscreen. It is quicker to apply and my little one can help without squeezing sunscreen everywhere. Will buy again.

Protection with days of white residue
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Mineral sunscreens have yet to master blending in and this is no different. If you're thinking of hitting the beach with your sexy bum protected it'd better be a ghost beach because you'll look like you've been dipped in white paint. Oh, and it doesn't wash off, so be prepared to look like Casper for days to come.
It rolls on fine if you shake it well first and it does protect.

Amazing!
Size: 2.5 Fl Oz (Pack of 1)
This sunscreen is amazing! I love that it goes on blue and then turns clear. It’s helping my kids learn to put it on themselves. It also stays on good and we haven’t had any sunburns even on the beach.
