About Us

Protection powered by the sea

CostaSea Suncare was born on the Florida coast, where the sun is relentless and the ocean is everything. We set out to make suncare that protects the people we love — without harming the sea we love just as much.

Our mission

CostaSea exists to protect the most vulnerable, through products that promote wellness, sustainability, and community impact. That mission shapes every formula we make and every cause we support.

Why mineral. Why reef-safe.

Every CostaSea sunscreen is a broad-spectrum mineral formula made with non-nano zinc oxide and free of oxybenzone and octinoxate — two chemical filters linked to coral reef damage. It is our way of giving you high-level sun protection while leaving no trace on the reef.

Giving back

We are proud to partner with the Kristin Tomasello Foundation. Every CostaSea purchase helps support children, families, and community initiatives — and through our 1% for the Ocean commitment, a portion of every sale funds ocean conservation.

Made in the USA

CostaSea is proudly made in the USA and designed for the whole family: clean, effective, and reef-safe, from our coast to yours.
