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.

    This the first body butter where I have literally scraped every ounce off the bottom of the container. This works so very well on mature crepey skin. My 31 year old daughter loves it too. It absorbs nicely into the skin and does not leave an oily residue. I highly recommend this product!

    Dislike the smell. I find it not as pleasant as the original product and see very little if any improvements in skin.

    I am on my second jar of this divine body butter. My skin stays nourished all day until the next morning! I love the smell and benefits of this body butter. I also gifted a set to my mom who is 80 and loves it too!
