Mineral SPF 30 Sunscreen Made for Sun Lovers

salt+blue for Real Protection. Real Care. Real Results.

1. Non-nano zinc oxide sits on the surface of your skin, where it reflects UVA and UVB without absorbing into your body. It doesn't break down in sunlight. It doesn't convert UV to heat inside your skin. It just works.

salt+blue is crafted with non-nano zinc oxide and antioxidant-rich botanicals that nourish your skin while providing reliable, mineral-based protection — without ever compromising your health.

Most conventional sunscreens take a different approach. They rely on chemical filters like oxybenzone and octinoxate — ingredients that absorb into your skin and bloodstream, where they can linger for weeks. These compounds have been linked to hormone disruption, irritation, and over time, may even weaken the very skin they’re meant to protect.

2. Chemical filters like avobenzone degrade in sunlight — sometimes within the first hour. Zinc oxide doesn't. The protection you apply in the morning is still doing its job in the afternoon.

salt+blue’s non-nano zinc oxide forms a stable, physical barrier that reflects UVA and UVB rays — delivering reliable, broad-spectrum protection that holds up through long days and real-life adventures. Whether you’re in the water, on a hike, or chasing sun with your kids, you’re protected.

Chemical sunscreens work differently. Instead of sitting on the skin’s surface, they absorb into the skin and convert UV rays into heat. But these filters — like avobenzone, octinoxate, and oxybenzone — can start to break down within minutes of sun exposure. As they degrade, the protection they offer becomes weaker and more uneven, leaving gaps that put your skin at risk. That’s why frequent reapplication is a must — and why many people unknowingly stay exposed.

With salt+blue, your mineral protection stays stable under the sun — so you can focus more on living, and less on whether your sunscreen is still working.

3. Some mineral sunscreens mix in titanium dioxide, which offers weaker UVA protection. Others use nano-sized zinc oxide particles small enough to absorb through the skin. salt+blue uses only non-nano zinc oxide — the most complete single-mineral option available, and the one that stays where it belongs.

Some "natural" brands blend zinc oxide with titanium dioxide, which offers weaker UVA protection and can irritate skin. Others use zinc oxide that’s nano-sized — small enough to absorb into your body.

salt+blue uses only non-nano zinc oxide, which stays on the skin’s surface — where it belongs — while offering the most complete UVA/UVB protection available from a single mineral.

4. The white cast problem with mineral sunscreen comes down to particle size. Ours are optimized to blend in without being small enough to absorb — smooth and sheer on every skin tone.

Thick, chalky residue is a deal-breaker for many. That’s because some zinc oxide particles are too large to blend in.

Our non-nano zinc oxide is small enough to blend invisibly but still large enough to avoid absorption into your bloodstream. The particles are optimized for a sheer, blendable application that disappears into your skin — no matter your tone.

5. Oxybenzone and octinoxate wash off in the water and have been linked to coral bleaching. We don't use them. Non-nano zinc oxide is considered the safest choice for marine life — which matters if the ocean is the reason you're wearing sunscreen in the first place.

Even small amounts of chemical sunscreen can disrupt marine ecosystems — damaging coral DNA and contributing to reef bleaching. And it's not just the formulas — non-recyclable, wasteful packaging often ends up in landfills or waterways, contributing to the pollution that threatens our oceans.

salt+blue is intentionally crafted to leave no toxic trace. Free from reef-harming chemicals like oxybenzone and housed in consciously chosen, recyclable packaging, our products are made to protect your skin while honoring the waters we all depend on.

No toxic runoff, no marine damage — just mindful sun care that lets you chase the sun, cherish the sea.
