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.

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 product - packaging an issue.

    I love the product - packaging has some issues. The last one delivered to me did not have an inner cap and the body butter had oozed out...

    Also - you may go by weight, but some orders have big air pockets - some don't. Not sure how they can weigh the same. All that being said, I love the body butter.
