Finally - the perfect sunscreen
Style: SPF 50, Size: 1 Count (Pack of 1)
I have become religious about using sunscreen - that's what one skin cancer scare will do to you. Since my laying out, baby oil/iodine days I have tried and tossed many sunsceens - facial sunscreens that melt, run and destroy my eyes, sunscreens that discolor my clothes. Enter Sun Bum Mineral - although I miss the sunscreen scent of summer, i will never go back. This brand delivers - rubs in easily, no ghostly cast (I am fair skinned), sprayers that actually spray, no killer eyes, protection that lasts thru sweat/swim. I am a true believer in this brand!

Great Protection w/out the White Cast
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
We had been using the ThinkBaby mineral sunscreen for years. I wanted to look for a similar alternative but with less white cast. I actually bought this on a whim because it had the fastest shipping at the time (needed it for an outdoor event we were going to). We are now three purchases deep with this product. In my opinion, I think it gives the same amount of sun protection as before without the white cast. It rubs in great. Non-greasy. Initially, the lack of added fragrance was a little off-putting because we were so used to the typical coconut or citrus scents, but we all got used to it. Definitely on my list of subscription purchases now. I wish it was available in a larger size.

Smells good, covers well, it does leave a white sheen, I don’t need to reapply.
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I use this just once on my face in the morning, apply makeup over it, and I haven’t burned yet! Been using it for two years now. Unfortunate thing is that my face is not tan at all because it doesn’t allow any rays. LOL So I my makeup has to match the rest of my body… I stay under an umbrella at the beach for about half of the time that I’m there. Otherwise I am out in the sun. And I do not reapply this. I am in the sun between the hours of 9 and 1 PM and I’m in and out of the shade and sun half of the time. Still no burning. Actually I don’t think I reapplied it at all once I got home from the beach and I was out at the pool regularly for another hour with no shade. So it seems to be pretty darn good! Some people say they don’t like the smell, but I specifically bought it because I love love love the coconut smell. My daughter says it smells like bananas but I don’t like the smell of bananas and I don’t think it smells like that.
It does definitely leave a white sheen. Hence my need for make up.

Great for Hawaii!
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I spent hours trying to find a sunscreen that was “reef safe” since I was going to be spending a lot of time near corals and this was the best one I found. It doesn’t have any of the 3 ‘O’ ingredients that are known to damage reefs. And the zinc is non nano as well.
Sunscreen goes on easily. One of the better mineral sunscreens I’ve tried, this one actually smooths out like lotion and feels hydrating. Only leaves a slight pinkish hue, but that is inevitable with mineral sunscreens (that’s literally how they work in reflecting the sun). I could feel it on even in the ocean so I get protected, but still reapplied almost every 2 hours. No burns!
I didn’t use it on my face but my partner did and it never stung his eyes nor caused any breakouts!
