Excellent mineral sunscreen for sensitive skin.
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!
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
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.

Gentle, hydrating with a slight white cast
Set name: Tube - 5 oz.
Really solid mineral sunscreen. Goes on smooth, not too thick, and feels lightweight but still hydrating. It does leave a slight white cast, which I actually like since it feels like better protection. The formula feels gentle and doesn’t irritate my skin. Great for daily use, and the UV color-changing cap is a nice bonus. Would repurchase.

Great sunblock.
Set name: Stick - 0.5 oz.
Love this stuff. It’s the only sunscreen that doesn’t sting my eyes. It works really well. It goes a long way. Lil dab will do ya. Maybe I use too much each application. I live in Florida and put it on my arms and face everyday. It does leave white smudges, smears and handprints on things.
