Every journey starts with a spark – a moment of inspiration that fuels a lifetime of purpose.

Ours is one of resilience, faith, and an unwavering commitment to leaving the world better than we found it. At CostaSea, our story begins with Kristin Tomasello – a passionate advocate for self expression, beauty and ocean conservation. Inspired by the need for safe, effective sun care that protects both people and the planet, she set out to create a sunscreen brand that reflects these values.

Proudly made in the USA, CostaSea is built on a foundation of responsibility and integrity. Our sunscreens are crafted with natural, responsibly sourced, reef-safe ingredients, and formulated to protect your skin while preserving the environment. We believe in caring for the earth and all who call it home, while making sure that you can enjoy the sun without compromise.

Join us to redefine sun care – one sustainable choice at a time.

About the Kristin Tomasello Foundation

The Kristin Tomasello Foundation supports individuals with special needs by providing a supportive atmosphere for the expressions of their unique gifts. It was born from a deeply personal place – one filled with love, empathy, and a mission to give back to the community. For Kristin, the foundation is much more than a charity, it’s a movement to remind the world that every life holds extraordinary value and deserves a chance to shine.

You can join Kristin in making a difference. Any and all support matters.
