Smart Sun Care Backed by Nature and Science

SPF, or Sun Protection Factor, is your skin’s first line of defense against harmful UVA and UVB rays—and at Stream2Sea, we take that seriously. Our range of mineral-based, reef-safe sunscreens offers broad-spectrum SPF 20, 30, 40, and 50 protection, empowering you to enjoy the outdoors with confidence and care.

Unlike chemical sunscreens that may absorb into the skin and disrupt marine life, our formulas use non-nano zinc oxide, a safe and effective mineral that physically blocks UV rays while staying kind to your body and the ocean. Each sunscreen is water-resistant, non-greasy, and enriched with botanical extracts like aloe vera, green tea, wakame seaweed, and olive leaf—ingredients that hydrate, soothe, and support healthy skin.

Whether you’re snorkeling, hiking, swimming, or running errands, you’ll find the right SPF for your lifestyle—with no white cast, no synthetic fragrances, and no compromise on ethics.

Biodegradable, ocean-safe, and proven safe for freshwater fish and coral larvae, Stream2Sea’s SPF protection is more than sun care. It’s a commitment to your well-being and the planet.

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