The best sunscreen on the market
Size: 5 Ounce (Pack of 1), Style: SPF 50+
The best sunscreen I've ever used. I burn super easy, just 30 min outside without protection and I'll be a lobster the next day. I can apply this once in the morning and be protected all day.
Pros:
- Doesn't wear off quickly
- Haven't had a single sunburn since I started using it
- Doesn't have a strong chemical smell
- A little goes a long way
- Resists sweat well
Cons:
- Has a white cast so you really have to rub it in
- It doesn't sit light, you can definitely feel it on your skin
I would recommend this to anyone and everyone looking for sunscreen.

Works well. Would buy again.
Size: 5 Ounce (Pack of 1), Style: SPF 50+
Perfect for Dominican Republic sun rays! No sunburn for my fair skin, still allowed slight color.

Love this sunscreen!!
Size: 5 Ounce (Pack of 1), Style: SPF 50+
This is my favorite mineral sunscreen. It goes on white, but the white cast leaves very quickly. The SPF 50 keeps me adequately covered in the Arizona sun and I've never gotten a sunburn when I have it on. It's a must have if you enjoy the outdoors in the summer.

Does seem different from blue bottle version
Size: 5 Ounce (Pack of 1), Style: SPF 50+, Size: 5 Ounce (Pack of 1), Style: SPF 50+
I have to say this one is interesting. I’m use to using the Blue Lizard in the all blue bottle for the better ingredients & still effective against UV rays with the only downside of the white cast. With that being said this one does dry m o r e clear, but does seem to take longer rubbing into the skin. I also noticed I get much darker/ more red when using this one compared to barely any skin change with the all blue bottle during a beach day. It still says 50+ SPF, but I have noticed more of a pattern of that happening. Depending on how much/ long I’ll be in the sun I might use the other instead, but if I am planning to go somewhere more of a social gathering I may use this one due to it drying clear.
