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.

    Thick and dreamy

    I am loving the Undaria Body butter for my skin right now! I might have to switch to a lighter moisturizer in the summer…but right now, as we shift between winter and spring, this is just what my dehydrated skin needs! It smells amazing, and absorbs beautifully 🫶🏻

    My ink loves it!

    This is not too greasy, my skin absorbs it like it's taking a drink. The fragrance is subtle alone and works together with the anti-aging body balm as well. I use it all over and especially on my ink on my chest, arms and back, and my skin loves it.
