Protect your skin—and the planet—with Natural Sun Protection that truly lives up to its promise. At Stream2Sea, our mineral-based formulas offer broad-spectrum UVA/UVB protection using non-nano zinc oxide, a naturally derived active that’s gentle on sensitive skin and safe for our oceans.

Unlike chemical sunscreens, our natural sunscreens are biodegradable, reef-safe, and made without oxybenzone, avobenzone, or other marine-harming ingredients. Each formula is enriched with plant-based antioxidants like green tea, wakame, aloe, and olive leaf to nourish your skin while you stay protected.

Whether you're snorkeling in crystal waters, hiking under the sun, or heading out for a beach day with family, you can trust Stream2Sea for natural sun care that works as hard as you do. Our sunscreens are water-resistant, non-greasy, and designed to blend in beautifully with no white cast—so you can enjoy the outdoors with confidence.

Feel good in your skin and even better about what you put on it.

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