Over 30 years ago, I started OSEA to share the healing powers of the sea. Since then, it’s been our mission to create clean, clinically tested skincare, combining pure, potent seaweed with active botanicals for results you can sea. My vision is to create waves of kindness for people and our planet.

FAQs

Undaria Algae™ Body Butter has the same beloved fragrance found in our Undaria Algae™ Body Oil and Undaria Algae™ Body Lotion. An all natural fragrance with uplifting grapefruit, lime and cypress combined with the sweet notes of mango mandarin.

It has a butter-rich texture that is fast absorbing and non-greasy!

Undaria Algae™ Body Butter has been formulated for use on the body, so we don't suggest it for the face. To experience the benefits of Undaria seaweed on your face, try our lightweight Atmosphere Protection® Cream.

If you’re looking for a fragrance-free option, try our Seabiotic® Water Cream or Advanced Protection Cream which also include Undaria seaweed and are suitable for sensitive skin.

Packaging: Jar is made of frosted glass. Cap (6.7 oz) is made of 50% PCR (post-consumer recycled) plastic.
Recycling: Please remove cap and dispose of it in the trash. Clean jar and put in your curbside recycling bin*.
*Before disposing in your recycling bin, please check if your local curbside recycling program accepts frosted glass.

    My second time purchasing body butter from OSEA. The skin absorbs it in seconds. The fragrance is subtle, the texture is luxurious. It is now a permanent component of my home SPA experience.

    Thick and Buttery

    Definitely on the thicker side but sometimes you need it! Personally it takes a little bit to dry down, but I don’t mind at all. Has the same amazing smell as the body oil - love!!

    The best

    I have been using this for years. As I get older I add a few drops of the oil to add a little more softness.
