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.

    Can't wait to shower to use it!

    I needed something to lift me up during a cold, Maine winter and I remember seeing this oil on instagram. I bought it thinking, "how special could it be?" OH, it's SPECIAL. I seriously can't wait for my nighttime shower routine so I can slather it on! It immediately makes me slow down, feels amazing, smells incredible and I swear my skin looks better after having used it. I need another bottle, stat.

    Body oil isn't for the driest skin it helps

    I never leave reviews, but this was too good not to share this is the best thing ever and then when I read it had like seaweed in it I was like oh gross but it is amazing and I have the driest skin everyone deserves to treat themselves worth every penny and you only have to use a little!

    Body oil review

    I love the smell of the product, it is so fresh and clean! I’ve only used it for about two weeks so I’m not completely sold on how well it is helping with my dry skin, but I’m definitely going to see it through for at least 30 days. It’s just my legs that I’m using it on because that is my most dry area on my body.
