About Us

Most sunscreen is built to protect your skin and ignore where it ends up. We started the other way around.

Stream2Sea was founded by Autumn Blum, a cosmetic chemist and lifelong diver who got tired of choosing between protection that works and ingredients she could actually defend. So she formulated her own.

Every sunscreen is built on non-nano mineral actives, zinc oxide or titanium dioxide, which provide broad-spectrum mineral sun protection. Our products are developed in Bowling Green, Florida, where every formula is carefully created with performance, transparency, and aquatic stewardship in mind.

The science isn't a tagline. Our Coral Care SPF 30 was studied at the University of Derby, where trials observed up to a 29% increase in healthy coral growth. We formulate products to be safer for aquatic life and continue to invest in research that helps us better understand the relationship between personal care products and aquatic ecosystems.

We use the term Reef-Safer™ because ocean health is complex. Rather than rely on broad environmental marketing terms, we focus on science-backed formulations and continuous improvement.

Protect what you love. For our blue planet.
