Fabulous product! Made my skin feel soft!
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
This product goes on smooth and a little goes a long way. I used it today for the first time and was very pleased that it held up to my sweating in the heat doing farm work! It doesn’t bother my very sensitive skin, in fact it is quite soothing. A little goes a long way. With about a quarter size amount I was able to do both arms and my face. I was outside for several hours and didn’t burn like I usually do. It is basically unscented which is nice and isn’t sticky.

Works well and neutral scent. Has white cast.
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
Not a bad sunscreen. I wore it yesterday at a water park, reapplied every 1-2 hours, and didn’t get burned. Works well as a sunscreen and has a very neutral scent, which I appreciate a lot. However, like most mineral sunscreens it feels a bit heavy and definitely has a white cast. I’m pretty pale and still had a hard time getting it to blend in. It’s priced well, available at many super markets, offers good protection, and the neutral scent means I will continue using it (I stopped using some other sunblocks because of the scent alone). Just know it feels heavy and has a white cast.

Favorite Mineral Sunscreen
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
This is my go to mineral sunscreen. It's very effective at protecting your skin from the harsh UV rays. It great to use for any water based activities, since it stays on your skin regardless of how wet it gets. I'm also able to use it under my eyes without it irritating them. Though it does leave behind a white cast after applying, but I personally don't mind it.

My favorite mineral sunscreen for Hawaii
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
My favorite mineral sunscreen for Hawaii. I just got back from a week in Maui. I took 3 different brands of mineral sunscreen. For Maui it has to say mineral to be allowed. Of the 3 the Blue Lizard was our favorite. It went on white but rubbed in the quickest. We applied in our room before going out for several hours and never got a burn the entire week. I only reapplied once on a hike. Would recommend Blue Lizard!

Great for very sensitive skin!
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
Use this every day. It's my primer. Lol I have extremely sensitive skin to the point where one wrong move lands me in the ER. This worked for me. Slight greasiness but works well for me as I can't wear foundation. This at least hydrates and protects. Love it.
