What the gurus are saying

This sunscreen delivers four-hour protection (double the standard window) with exceptional water resistance and staying power, making it a standout choice for extreme activities like skiing where reapplication isn't practical. However, it contains denatured alcohol, which concerns some experts who worry about skin barrier damage, especially during outdoor sweating. The trade-off is worth considering based on your activity and skin sensitivity.

"Ultrasun is [...] one of my favorite sunscreen brands, they do the extreme wear products really well, and it ticks so many boxes. It's not the cheapest product out there, but for specific circumstances like skiing or hiking where you don't need to reapply as often, I think it's a really, really good option that delivers that longwear extreme protection without feeling super heavy on the skin."

"The next product I get asked about a lot is Ultrasun SPF 50 Extreme. So it's okay, chemical mineral hybrid, so it's both. It is fragrance free which I like, but again it does contain denatured alcohol. So again for me this one is a no, especially if you're outside, you're sweating already, damaging your skin barrier. Why would you put a product with denatured alcohol in the skin? It makes no sense."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Sunscreen filters

Sun protection is the best evidenced way to slow visible ageing, and the filters are what does the work. Mineral and chemical filters both protect when a product is applied thickly enough and often enough, which is where most people fall short rather than on the choice of filter.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
