Brand

OSEA

OSEA was founded in 1996 by Jenefer Palmer in Malibu, California, making it one of the original clean beauty brands -- launched years before the clean beauty movement had a name. The brand's name stands for Ocean, Sun, Earth, Atmosphere, reflecting its commitment to harnessing marine and plant-based ingredients. OSEA's formulations center on seaweed and algae sourced from Patagonian waters, chosen for their high mineral content and bioavailability. The Undaria Algae Body Oil became the brand's breakout product, earning a devoted following for its fast-absorbing, non-greasy texture and sea-derived nutrients. OSEA is certified Climate Neutral, Leaping Bunny cruelty-free, and uses sustainably sourced seaweed. The brand is sold through its own website, Sephora, and Nordstrom.

Brand Philosophy

OSEA believes the ocean holds the most potent skincare ingredients on earth, and that clean formulation is non-negotiable. Every product is vegan, cruelty-free, and free from parabens, petroleum, and synthetic fragrances. The brand's seaweed-first approach provides minerals, vitamins, and amino acids that support skin barrier health. OSEA treats sustainability as foundational -- Climate Neutral certified and committed to ocean conservation -- rather than as a marketing addition.
