Collection: Highest SPF Sunscreen

When it comes to sun protection, higher SPF means greater defense—and at Stream2Sea, we deliver that without compromising your health or the planet. Our Highest SPF Sunscreen collection features broad-spectrum mineral formulas designed for long-lasting protection, even in the harshest sun.

Formulated with non-nano zinc oxide, our sunscreens offer powerful UVA/UVB coverage while remaining reef-safe, biodegradable, and gentle on sensitive skin. Whether you're snorkeling in tropical waters, hiking high altitudes, or simply spending hours outdoors, these high-SPF formulas stay put—resisting water, sweat, and harsh environmental elements.

But high SPF shouldn’t mean heavy or greasy. Stream2Sea sunscreens absorb smoothly, leave no white cast on most skin tones, and are free from oxybenzone, octinoxate, parabens, and other harmful chemicals. We also enrich every formula with antioxidant-rich ingredients to support your skin barrier while you’re out in the sun.

High-performance sun care that’s safe for your skin—and the sea.
