FAQs

Undaria Algae™ Body Oil

Yes! This oil contains Undaria seaweed, so you may find naturally occurring seaweed sediment at the bottom of the bottle. It may not be visible at first, as it takes time to settle. This is normal and doesn't affect the product's quality or efficacy.

After cleansing with our Undaria Algae™ Body Wash, apply Hyaluronic Body Serum to dry or damp skin from the neck down. Then, generously massage Undaria Algae™ Body Oil as the last step in your body care ritual for silky, glowing skin. Undaria Algae™ Body Lotion or Undaria Algae™ Body Butter also work great layered under Undaria Algae™ Body Oil for an added boost of hydration.

It is typical for the Undaria Algae™ Body Oil to range in color from golden to emerald green. The color does not impact the quality or efficacy of the product.

To create this one-of-a-kind oil, we soak hand-harvested Undaria algae in barrels of oils to infuse the vitamins and minerals. Due to the artisanal manner of production, variation in color is normal.

We use all-natural ingredients to create the fragrance of our products. The scent may vary slightly from batch to batch.

Undaria Algae™ Body Lotion

A lightweight lotion that instantly absorbs and leaves a silky smooth finish.

After cleansing with our Undaria Algae™ Body Wash apply Hyaluronic Body Serum to dry or damp skin from the neck down. Then, generously massage Undaria Algae™ Body Lotion. If you're looking for a glowier finish and extra hydration, follow with Undaria Algae™ Body Oil or Anti-Aging Body Balm.

Undaria Algae™ Body Lotion 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.

    I like the lotion better than the oil. That's just my personal preference. It smells great and doesn't feel sticky or oily.

    love it

    This oil smells amazing and leaves your skin glowing without being super greasy. It absorbs best for me on wet skin, but I have also mixed it in with their other lotions and it works great.

    Somewhat happy

    The jury is out on the product. I'm pushing 60, and over the last 2 years have lost 60 pounds, which has contributed to my wrinkles. I haven't really seen much difference. Although I'm going to continue using it for a few more months.

    Best regards,

    Stacie

    Ultra moisturizing if done right

    We alternate between this oil and another brand all year round. The trick to this is not applying it to dry skin, it needs to go on damp skin for full penetration. I happened to purchase the body balm and serum and when combined it does an incredible job of saturating moisture into the skin, especially during the winter months. We also add the butter balm to our routine when the east coast hits fall weather. My husband suffers from itchy dry skin in the winter so we must always have the whole combo on-hand. And the smell is divine!
