Safer Choices for You and the Sea by Stream2Sea

At Stream2Sea, we believe in transparent sun protection that honors both your health and our oceans. While many sunscreens are made with chemical UV filters that may harm marine life, Stream2Sea proudly formulates only with mineral-based (physical) sunscreen actives—never chemical filters like oxybenzone or octinoxate.

Our sunscreens rely on non-nano zinc oxide, a physical UV blocker that sits on your skin to reflect harmful UVA and UVB rays—offering broad-spectrum protection without absorbing into your body. Unlike chemical sunscreens that rely on synthetic filters and can irritate sensitive skin, Stream2Sea’s mineral formulas are gentle, reef-safe, biodegradable, and scientifically proven safe for fish and coral larvae.

Whether you’re kayaking, snorkeling, hiking, or lounging under the sun, our water-resistant SPF products deliver high-performance protection with no white cast, made with nourishing ingredients like green tea, aloe, wakame, and olive leaf.

Even as the market is filled with both physical and chemical options, Stream2Sea stands firmly in the mineral camp—for your health, for marine ecosystems, and for a cleaner planet.

High-performance sun care by Stream2Sea that’s safe for your skin—and the sea.
