Undaria Algae™ Body Oil
For a full-body glow
5 fl oz / 150 mL
Description
Clinically shown to instantly improve the look of skin elasticity and deliver deep moisturization. Our seaweed-infused body oil is a rush of antioxidant-rich hydration that softens, nourishes and firms like no other. Rich yet never greasy, this intoxicating aromatherapy elixir enhances every inch. Mineralize, moisturize and glow!
Also available in fragrance-free, which is hypoallergenic, dermatologist tested and safe for sensitive skin.
To create this one-of-a-kind oil, we soak hand-harvested Undaria Algae™ in barrels of botanical oils to infuse the vitamins and minerals. Due to the artisanal manner of production, variation in color is normal. This oil contains Undaria Seaweed and as such, a naturally occurring seaweed sediment may be present at the bottom of your bottle. This is completely normal and does not affect the quality or efficacy of the product.

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.
Hyaluronic Body Serum
A body serum is a lightweight skincare product formulated to address dryness or dullness. Serums are often highly concentrated to ensure nourishing ingredients reach beneath the surface of the skin. A body serum with hyaluronic acid helps deliver moisture, as hyaluronic acid acts as a humectant, making it highly effective at attracting and retaining moisture.
If your skin feels dry, our Hyaluronic Body Serum can help improve your skin’s natural moisture barrier by providing multi-layer surface hydration for 24 hours.
Apply our body serum onto clean, slightly damp or dry skin from the neck down. For best results, use the serum twice daily—once in the morning and again at night. Hyaluronic acid draws moisture into the skin, so slightly damp skin is ideal.
Use it year-round for all skin types, especially for dry or parched skin. Both cold and warm climates can dry out the skin, making this serum essential for maintaining smooth, hydrated skin.
Our body serum is designed to be layered under a body moisturizer for maximum hydration, but some skin types may find it hydrating enough on its own, particularly in warmer months. To maximize your results, follow with your favorite OSEA body moisturizer.

Love the scent and like the way it feels on my skin. I feel like I need more on since my skin is dry…I’m 78.
I will continue using it love it so far!
- DLDonna L.Verified BuyerReviewingUndaria Algae™ Body OilI recommend this productWhat best describes your skin? Mature & DryHow old are you? 45-60Rated 5 out of 5 stars2 days agoUltra 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!

How it made my skin feel
- SNSamantha N.Verified ReviewerReviewingHyaluronic Body SerumI recommend this productWhat best describes your skin? Normal & CombinationHow old are you? 35-44Rated 5 out of 5 stars3 days agoMy holy grail body serum
I’ve tried so many body serums, and this hands down takes the cake. It absolutely moisturizes my skin and leaves it feeling incredibly soft and smooth without feeling heavy or sticky.
This is one of those products where I genuinely notice a difference when I use it consistently. Absolutely worth it for me and something I’ll keep repurchasing.
- EAEbru A.Verified BuyerReviewingUndaria Algae™ Body OilI recommend this productWhat best describes your skin? Sensitive & ReactiveHow old are you? 25-34Rated 5 out of 5 stars3 days agoI need this in Eastern Europe
Last year I was looking for a body oil that doesnt leave marks on my clothes. I used the algae for 4 months and then stopped as my supply run out and I wasn’t able to find any on EU. The effect this oil had on my body lasted for months afterwards - can’t be happier with my choice!
Now I’m back and got it again. Besides their products, I praise the service they have - they have a world class support team, thank you ever so much for everything!
