Protect your skin with confidence using Stream2Sea’s Mineral Sunblock, a high-performance, reef-safe formula designed for eco-conscious adventurers. Made with non-nano zinc oxide, this broad-spectrum SPF offers powerful protection against UVA and UVB rays—without synthetic chemicals or a heavy feel.

Whether you’re spending the day snorkeling, surfing, hiking, or just soaking up the sun, our water-resistant mineral sunblock glides on smoothly with no white cast and stays put, even through sweat and waves. It’s enriched with antioxidant-rich botanicals like green tea, olive leaf, wakame, and aloe, which help nourish and soothe your skin while providing long-lasting defense.

Formulated without oxybenzone, parabens, or sulfates, this biodegradable sunscreen reflects our deep commitment to protecting both your health and our fragile marine ecosystems.

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