OSEA founder Jenefer Palmer seated with a laptop in front of OSEA skincare products.

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 have used this in past years and thought I'd try it again. I wish it would absorb a bit more into my skin, arms.
