Love the lotion, hate the browning cream
Love the lotion have used multiple bottles. It really does help prolong a suntan. Very moisturizing very nice scent. Like a you know Hawaiian tropical coconut pineapple scent little plumeria in there. But the bronzing cream stinks to high heaven. It was sticky and it was gross so I never used it and I won’t buy it again. Definitely by the lotion, but not the bronzer.

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.
