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.

    Solved My Cracked Elbows

    Helped get rid of my very dry elbows that I had tried multiple different body butters for. This was the first that worked.

    My new favorite

    I work everyday day. Hard work, like fencing and milking cows. I’m a farmer. My hands are sometimes rough because of it. Not anymore! This body butter feels like pure luxury when you put it on. It is not greasy and absorbs well. I get compliments on how soft my hands are. That’s a first!

    I will be trying the skincare line.

    The Best

    This body butter is the best body butter on the market. It heals the skin as well as moisturizes. I recently had some dermatological work done. My skin is healing so much much faster when I use this body butter. Even my old blemishes are fading. My body is worth it.

    No better body butter!

    I have an deep fondness for Osea, products and mission. I am 72, love the sun, and skin issues are occurring. I love to be soft and as smooth as atmospherically possible. I have used all of the body care. I have found a combo that delights all my senses. I start with the balm, then layer the butter, then layer the oil. I use the salt scrub in the shower and actually shave with it. If there is a way to be more supple, I would try it. I have been using the sample of Dream lotion at night. What a lovely sensation before bedtime, both tactile and aroma.
