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.

If you live in the Los Angeles area, you can participate in our Recycling Program at our Venice Skincare Studio. Find all the details here.

    Love the consistency and immediate moisturizing feeling of my hands. That’s why I mainly purchase this product: extremely dry hands.

    Did not love the fragrance - too strong- but does not bother me. I really recommend this product.

    The body butter is ok. It’s difficult to spread & can start rolling up on skin. I have to apply on damp skin to get better results.

    I really wanted to love OSEA. I support the ingredients but even the balm doesnt leave my skin soft and smooth the way organic tallow does. I am really disappointed as I was looking for a lotion to use intermittenly.

    Truly sorry
