Collection: Zinc Only Sunscreen

Discover the pure power of zinc-only sun protection with Stream2Sea’s mineral-based sunscreens, crafted exclusively with non-nano zinc oxide—no titanium dioxide, no chemical filters. Designed for outdoor lovers and water enthusiasts, this collection offers broad-spectrum SPF coverage that’s safe for your skin and the delicate ecosystems you love to explore.

Each formula in our zinc-only sunscreen range is water-resistant, reef-safe, and leaves no white cast, making it suitable for all skin tones. Whether you're diving in coral reefs, kayaking under the sun, or enjoying a beachside hike, these sunscreens shield you from UVA/UVB rays using only nature-derived, biodegradable ingredients.

Enriched with antioxidant-rich botanicals like green tea, aloe, wakame, and olive leaf, our zinc-only sunscreens soothe and nourish while providing reliable defense from sun damage. As with all Stream2Sea products, you’ll never find parabens, oxybenzone, or octinoxate—only clean, science-backed, ocean-safe ingredients.

Embrace worry-free sun care that’s good for you and the blue planet.

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