Heritage & History
OSEA was founded in 1996 in Malibu, California by Jenefer Palmer, who had spent years researching the nutritional and therapeutic properties of seaweed and marine plants for skincare applications. The brand name — OSEA — is an acronym for Ocean, Sun, Earth, Atmosphere, reflecting the elemental, nature-derived philosophy at the heart of the brand.
OSEA built its following in the luxury clean beauty market through spas, resort hotels, and high-end retail before the broader clean beauty movement made the category mainstream.
Made in Malibu, California
All OSEA products are formulated and produced at the company's Malibu, California facility. The marine botanical ingredients are sustainably harvested and processed domestically; the formulations are developed by the OSEA team in Malibu; and the finished products are filled and packaged in California.
The product line covers full facial skincare: cleansers, toners, serums, moisturizers, masks, and eye treatments, all built around seaweed and marine botanicals. For consumers who want luxury clean skincare with traceable marine ingredients and California manufacturing, OSEA provides nearly 30 years of Pacific-sourced, California-made clean beauty.
