Stream2Sea’s Non-Nano Sunscreen is your go-to choice for safer, effective sun protection that’s gentle on your skin and kind to the planet. Formulated with non-nano zinc oxide, this mineral sunscreen creates a physical barrier that offers broad-spectrum UVA/UVB protection—without penetrating the skin or harming delicate marine life.

Unlike chemical sunscreens, our non-nano formula sits on the skin’s surface, reflecting UV rays and reducing your exposure to irritating or hormone-disrupting ingredients. It’s water-resistant, non-comedogenic, and blends in smoothly with no white cast, making it ideal for daily use, even on sensitive or acne-prone skin.

But this sunscreen goes beyond defense. Enriched with soothing botanicals like green tea, aloe, wakame, and olive leaf, it hydrates, calms, and supports your skin barrier—especially after time in the sun.

Whether you're snorkeling, hiking, or simply out and about, you can trust our formula to stay in place and perform without polluting the waters you love. It’s biodegradable, reef-safer, and 100% formulated without oxybenzone, octinoxate, and other ocean-harming chemicals.

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