Safe Sun Protection by Stream2Sea

Stream2Sea’s Non-Nano Zinc Sunscreen collection is sun protection you can truly feel good about. Designed for adventurers, ocean lovers, and families who care deeply about what goes on their skin—and what goes into the water—our formulas deliver high-performance, broad-spectrum SPF powered by non-nano zinc oxide, a naturally safer and more environmentally responsible UV blocker.

Unlike chemical sunscreens that may harm marine life, our non-nano zinc sunscreens are reef-safe, biodegradable, and ocean-friendly, offering water-resistant protection without compromising the planet. The formulas glide on smoothly with minimal to no white cast, and are enriched with skin-loving botanicals like green tea, aloe, wakame, and olive leaf for added antioxidant support.

Perfect for beach trips, snorkeling, paddleboarding, hiking, or everyday wear, these sunscreens are formulated without oxybenzone, octinoxate, parabens, and sulfates, making them ideal for even the most sensitive skin types—including kids.

With Stream2Sea, you're choosing a science-backed, mineral-based sunscreen that protects both your skin and our waters—naturally.

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