At Stream2Sea, we believe sun protection should never come at the ocean’s expense. If you love the high SPF and tropical feel of Hawaiian Tropic Sunscreen SPF 50, but care about reef safety and eco-conscious choices, our mineral-based alternatives are made just for you. Our sunscreens offer SPF 50 broad-spectrum protection using non-nano zinc oxide—effective against both UVA and UVB rays, yet gentle on your skin and safe for marine life.

Water-resistant and enriched with nourishing ingredients like green tea, wakame, aloe, and olive leaf, our formulas provide lasting protection without the greasy feel or white cast. Whether you're paddleboarding, kayaking, snorkeling, or just soaking up the sun, you’ll have the peace of mind knowing your sunscreen is both skin-safe and planet-friendly.

Unlike many mainstream sunscreens that contain harmful chemicals like oxybenzone or octinoxate, every Stream2Sea product is biodegradable and rigorously tested for freshwater and saltwater safety.

For those who love the sun but love the ocean more—choose a smarter, safer SPF that aligns with your values.

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