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

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 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!

    Travel size not suitable for travel

    This is my third time purchasing this oil in the travel size….for travel. I had no issues with the first two orders. This last time it arrived in a box, but without the clear plastic cap needed to prevent it from leaking during travel/transit. I bought this size specifically to travel with. and it is unsuitable for travel.

    Love

    This is the nicest body lotion I’ve ever used and the fact that it is clean and fragrance free is such a plus and I feel good about putting it on my body. It’s not sticky or perfumey and I just love it. It’s simple and makes my skin nice and soft. I will definitely buy again when I run out.

    Smooth and Silky

    This moisturizer goes on very smooth and silky and dries very quickly. Then use it with the OSEA oil to lock it in!

    Amazing

    Didn’t realize how thirsty my skin was!! Love the nourishing feeling and the amazing texture of my skin after using this oil. I actually combine one pump of the oil with the body lotion- and am very happy and pleased with my purchase.
