good consistency
Style: SPF 30, Size: 3 Ounce (Pack of 1)
It is a body lotion and for that it's great but it's a bit white for face unless you are very fair. Not shiny which is a plus and goes on evenly.

This is the only sunscreen that doesn't give me an allergic reaction
Style: SPF 30, Size: 3 Ounce (Pack of 1)
I've tried many other sunscreens and all of them give me an allergic reaction, or they are very thick and leave a white residue. This, though, does neither of those things. It's just the right consistency. I've purchased this twice now and will purchase more in the future, I'm sure.

Best mineral sunscreen
Style: SPF 30, Size: 3 Ounce (Pack of 1)
Applies easily, smells great and hardly leaves a whitecast! One of my favorite mineral sunscreens that I’ve tried.

White film left
Style: SPF 30, Size: 3 Ounce (Pack of 1)
I know that mineral sunscreen is the best. But this one will leave a white film on you. I have used other sunscreens that work without the white film.

You get Zink, but no “tropical” scent
Style: SPF 30, Size: 3 Ounce (Pack of 1)
Great product. I wanted a Zink based sunscreen for my face, but I was hoping it would still have the Sun Bum traditional “tropical” scent. Sadly nope. I’m mixing it with the traditional Sun Bum 30 so I can get my tropical feel while keeping my face safe from sun damage. Hopefully I don’t turn green :)
