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.

Best sunscreen product ever
This is the best sunscreen I have come across! I love that it goes on like normal sunscreen, but then dries so there’s no greasy slimy feeling. I have used this and only this since I have found this product. It is reasonably priced and offers great protection. I am a very fair skinned redhead and I have not once burned while using it. I highly recommend this product it is the best sunscreen you can get.!

Doubles as a facial moisturizer
Goes on easily and works effectively. I noticed how smooth my face has become since I began using this product. Great product especially for me since I am concerned with skin safety.

Good sunscreen great price
Seems to work well. Feels good on my face. Does leave a white cast but it's not as bad as other sun screens like the Neutrogena sport face. I wear it at work so I don't care.
Edit- this sunscreen seems to break down some plastics. I've gone through two cheap sunglasses lol
