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.

    Great lotion

    This is a great product if you want a bit heavier feel with your moisturizer, I really liked it but I personally prefer the lotion a bit more.

    Body butter

    I first got the small box to see if I like the product. I am allergic to a lot of things so finding natural ingredients is a must. I absolutely love this butter. It is soft, sensual, and makes your skin buttery soft. Try it you will not regret pampering yourself!

    Undeniable High Quality!

    I decided to try the body butter when I treated myself to the 9oz body oil this time around! Osea body butter did not disappoint, same scrumptious citrus sent as the oil, in a not to heavy but luxurious feeling butter. This brand has become a top choice for me. Worth every penny!

    Body Butter Bliss

    This body butter is very rich - but sinks into skin so not greasy. Has a lovely citrus scent, which I really like, but may not be for everyone. An accompanying spatula, to best get the product out of the jar would be welcome!
