Over 30 years ago, I started OSEA to share the healing powers of the sea. Since then, it’s been our mission to create clean, clinically tested skincare, combining pure, potent seaweed with active botanicals for results you can sea. My vision is to create waves of kindness for people and our planet.

FAQs

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.

Uplifting grapefruit, lime and cypress combined with the sweet notes of mango mandarin.

Undaria Algae™ Body Oil 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 Dayglow Face Oil™ - they are created in a similar way, however, Dayglow Face Oil™ is a moisturizing face oil that delivers instant radiance to dry, sensitive skin.

Here's a step-by-step guide to help you unlock and use your pump effectively:

1. Hold your product firmly to prevent it from spinning as you try to unlock the pump.
2. Locate the small white plastic circle right below the pump's neck and hold it tightly.
3. Using your other hand, turn the pump counter clockwise to unlock it. Note that you do not need to push down while you twist, as our pumps do not 'pop up' once unlocked.
4. To prime the pump, press down a few times until the product dispenses.

Packaging: Bottle is made of frosted glass and pump is made with 50% PCR (post-consumer recycled) plastic.
Recycling: Remove pump and dispose of it in the trash. Clean bottle and put in your curbside recycling bin*.
*Before disposing in your recycling bin, please check if your local curbside recycling program accepts frosted glass.

If you live in the Los Angeles area, you can participate in our Recycling Program at our Venice Skincare Studio. Find all the details here.

Reviews Summary
Customers say this body oil absorbs quickly without leaving a greasy residue. Many praise its light citrus scent and how it leaves skin feeling silky smooth. The oil works well after showers, with users noting lasting hydration. While most find it effectively moisturizing, some mention it's pricey and a few prefer more intensive hydration for winter use.

    Keeps legs smooth and silky

    Great to moisturize my older skin which can tend to feel dry. I use it at least once a day.

    This is an awesome product! It smells amazing. My skin has been very dry lately due to surgery. The oil absorbed quickly and my skin came back to life! Thank you!

    A bit deceiving!!

    I had tried OSEA samples several times before purchasing the full-size product and absolutely loved them. The scent was fresh, rich, and luxurious, and the oil felt deeply moisturizing on my skin.

    Unfortunately, my experience with the full-size version was completely different. The product I received had a noticeably fishy/off smell instead of the clean scent I remembered from the samples, and it didn’t feel as enjoyable to use. Since I purchased it from Ulta, I’m not sure if I may have received an older or defective batch, but the difference was significant enough for me to notice immediately.

    I still love the concept of the product and the experience I had with the samples, but the inconsistency—especially considering the price point—was disappointing.

    Hydrating and healing

    Not only did my skin drink up the body oil, it also helped with some hyperpigmentation that was a result of a rash.

    Holy grail!

    This is the most amazing body oil I have ever used! After using it for about a month, I can see such a difference in my skin. Smoother texture, softness, and moisture! Amazing product!
