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.

- SCSarah C.Verified BuyerReviewingUndaria Algae™ Body OilI recommend this productWhat best describes your skin? Normal & CombinationHow old are you? 60+Rated 5 out of 5 stars5 days agoWorks well on crepey upper arms
I bought this to help combat the crepey skin on my upper arms. I read reviews, which were pretty positive, and I can say that with daily use over the course of 4 or so months, I have noticed a remarkable improvement in the way my arms look. It didn’t happen overnight, but I am feeling great about the progress. I am even planning to wear a short sleeve dress to a wedding soon!

Feels nice and smooth but see zero difference in hydration. Have tried applying to damp skin and dry. Once a day and twice. No improvement. Perhaps it’s made for younger skin to ward off dryness. Won’t buy again.

I have very dry skin and this product works so well for me. I use it once or twice a day. It is hydrating and soothing but not greasy. I love the light scent.
