Excellent mineral sunscreen for sensitive skin.
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
I’ve been using the Blue Lizard Sensitive Mineral Sunscreen, and it’s become a staple in my routine. As someone with sensitive skin, I really appreciate that it’s fragrance-free and uses zinc oxide, providing great protection without causing any irritation or breakouts. It goes on smoothly, isn't overly greasy, and the water resistance holds up well for outdoor activities. The smart cap technology is a nice touch, too. Highly recommended if you’re looking for effective, non-irritating sun protection.

No chemicals that will be harmful!
Size: 5 Fl Oz (Pack of 2), Set name: Tube - 5 oz. 2-Pack
Ordered this mineral sunscreen looking for something simple and effective, and it’s been a solid option so far.
The zinc oxide formula is the main reason I went with it. It doesn’t rely on the same chemical ingredients found in a lot of other sunscreens, which is a big plus if you’re trying to avoid that. It feels like a cleaner option overall.
Coverage is good. It spreads evenly and holds up well, even with some water exposure. I’ve used it outdoors for extended periods, and it does its job without needing constant reapplication.
It does leave a slight white cast at first, which is pretty typical with mineral sunscreens, but it fades in as you rub it in. Not completely invisible, but manageable.
After a few uses, what stood out most is that it doesn’t have a strong smell and doesn’t irritate the skin. It just works without a lot of extras.
Compared to standard chemical sunscreens, this feels more straightforward and less harsh, especially for regular use.
For the price, it’s a great value. You’re getting strong sun protection without the added ingredients some people try to avoid.
If you’re looking for a mineral-based sunscreen that’s effective and a bit cleaner in formulation, this is a solid choice.

Great mineral sunscreen that actually works
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
Blue Lizard Sensitive Mineral SPF 50 has become my daily go-to. It goes on smooth, doesn’t leave a weird white cast like some mineral sunscreens, and gives solid protection. I like that it’s 100% mineral with no harsh chemicals and has organic aloe vera in it, so my skin feels hydrated instead of dried out. No greasy feeling, no strong scent, and it holds up well even when I sweat a bit. Been using it for a few weeks now and it performs exactly how I want. Small bottle but a little goes a long way. Definitely recommend if you want a simple, effective mineral option.

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.
