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.

    Has Caffeine!

    Purchased this as I have recently lost weight and my skin took a hit. Wanted a firming cream I could use day and night. Was wondering why my sleep was off and saw this had caffeine as an ingredient. Can. no longer use at night and if the disruption continues may have to stop using entirely. I'm very sensitive to caffeine.
