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.

    New Formula is Disappointing

    I was so sad when I repurchased the body butter and it was a different consistency and smelled bad…almost chemically. I thought I got a bad batch. They sent a replacement and it was still bad. Then I asked if they changed the formula. It was changed in November of 2024. It used to work so well for my mom and I! And was truly anti-aging . It just doesn’t moisturize and absorb as well anymore. Very waxy. And I can’t stand the smell anymore. Please change it back OSEA!

    Absolute luxury in a jar!

    Feels like a mini spa retreat every single time. It melts in beautifully, leaving my skin deeply hydrated, silky smooth, and never sticky.

    Soft and smooth

    This moisturizer is a big step up from the others. I immediately felt the butter texture. You don’t need as much as the others. A little goes a long way. High quality. No greasy feeling. Adorbs quickly. Highly recommend.

    Winter hydration

    This body butter is the ONLY body butter I have ever used that is not tacky feeling and actually soaks into my skin. The smell is so heavenly which is perfect for my self care routine. Highly recommend, especially if you live in a cold, dry climate like me.
