What do Blue Lizard sunscreen reviews get right about sensitive skin?

How mineral sunscreen actually blocks the sun

Here's the mechanism buried under the SPF number. Most sunscreens use chemical filters like avobenzone or oxybenzone, which soak into the top layer of skin and absorb UV energy, converting it to heat and releasing it. That absorption step is where the sting and the rashes usually start, because those molecules are small enough to react with skin that's already reactive. Blue Lizard skips that step entirely. Its active ingredients, zinc oxide and titanium dioxide, are mineral filters that sit on top of the skin instead of soaking in, and they work by physically scattering and reflecting UV rays before they reach living cells. Nothing has to absorb, nothing has to convert, so there's less for sensitive skin to argue with. That's also why the label can say fragrance-free and paraben-free and mean it, there isn't a chemical cocktail underneath doing the actual blocking. The trade for that gentleness is the white cast you rub in, and it's a real trade, not a myth. The formula also carries organic aloe vera, which does the boring but useful job of keeping that barrier from feeling tight or dry on skin that's already touchy. The bottle's Smart Cap changes color under UV light, a small nudge to reapply since the mineral layer wears down with sweat, water and toweling off rather than breaking down chemically. And because it skips oxybenzone and octinoxate, the same molecules blamed for coral bleaching, it's one of the formulas that doesn't force a choice between your skin and the reef you're swimming over.
