FAQs
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 cleansed, 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. For enhanced results, follow with our Undaria Algae™ Body Lotion and then seal in the moisture with Undaria Algae™ Body Oil.
Hyaluronic acid is a lightweight substance that retains moisture, making it a powerful addition to hydration-focused skincare routines. It’s naturally found in the body, from your joints to your skin, where it helps keep everything lubricated and hydrated.
Over time, the body produces less natural hyaluronic acid. Our Hyaluronic Body Serum replenishes moisture and locks in hydration, leaving skin feeling soft, smooth, and youthful.
Our Hyaluronic Body Serum is made for sensitive skin and can be used on all skin types. It’s oil-free, fragrance-free, and dermatologist-tested.
However, it's formulated specifically for use on the body and is not suitable for the face. If you’re searching for a hyaluronic acid in your facial skincare routine, try our bestselling Hyaluronic Sea Serum.
Our body serum has a lightweight gel texture, without any sticky or tacky afterfeel, making it easy to apply and absorb into the skin.

I like it so far even though it’s only need a week. I can even use it in my face without a reaction.

Love this! My skin feels silky smooth and healthy
- SSandraRated 5 out of 5 stars1 week agoMakes my skin glow!
I love this body serum. I apply it before the Undaria Body Oil. It makes my skin glow and keeps it moisturized for the rest of the day!
- NBNicole B.Verified BuyerRated 5 out of 5 stars1 week agoAMAZING
Purchased at a Credo in Venice, CA!
I don't really incorporate hyaluronic acid in my skincare routine. My face doesn't get too dry, so I never really felt the need for it. Anytime I do receive a hyaluronic acid serum, I just finish it up to get rid of it or gift it to a friend or family member.
However, the skin on my body is a lot different. Over the years, my skin has become drier and just irritated. I do have the OSEA Undaria Algae Body Oil and Body Butter which I primarily use as part of my evening bodycare routine. But when I added this baby, it just leveled up my body care.
This lightweight, gel-like serum instantly cooled and soothed my skin especially after my post-morning walk shower. It applies so easily and nicely, and it settles on my skin without a sticky or tacky residue like a lot of serums. No lies, within two weeks, my skin has felt softer than ever before - it's even helping reduce my annoying KP texture skin on my arms 😭 As soon as my first bottle was running low, I immediately subscribed and bought my second bottle.
Thank you for another amazing product OSEA!
- TTaylorVerified BuyerRated 5 out of 5 stars2 weeks agoAbsolutely Love!!

The Hyaluronic serum is great for older skin elasticity.
- JGJennifer G.Verified BuyerRated 5 out of 5 stars2 weeks agoBody Serum
This feels like silk going on, I love it! Especially for the dryness of winter. It's light enough to layer under the lotion, but I can feel it working right away. Great product!
