Undaria Algae Body Oil

Clean formula, honest packaging disclosure. Swap the pump for a pour cap and this is as close to plastic-free as body oil gets.

About OSEA

OSEA is a family-owned, mother-and-daughter company founded in 1996 in Malibu, California, by Jenefer Palmer and now led by her daughter Melissa, inspired by a great-grandmother who believed in the healing power of the ocean. It makes clean, seaweed-based skincare, including cleansers, face oils, moisturizers, and its Undaria Algae Body Oil.

It is certified vegan by PETA and Leaping Bunny cruelty-free, and it carries the Climate Label for measuring and reducing its carbon footprint, and it was an early signer of the Campaign for Safe Cosmetics. Positioned at the prestige end, its sustainability story is really about clean marine ingredients, glass packaging, and climate labeling rather than refills.
