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 wish i could give this more than 5 stars!!! I have a lot of sun damage on my arms and this REALLY helps! Love this!!!
- LFLaurie F.Verified BuyerRated 5 out of 5 stars2 days agoOSEA body serum
Very hydrating
- JJulieRated 3 out of 5 stars2 days ago3/5 but wanted to love
I really wanted to love this, but it’s not as hydrating as the body butter and even left my skin crepey. I’m
46 and now apparently need lotion so thick to slather on that this is for the younger one. I did finish that bottle but I’m still a very loyal OSEA customer
- ESElizabeth S.Verified BuyerRated 3 out of 5 stars3 days agoOnly ok
I would not purchase this product again.
- EErinRated 5 out of 5 stars4 days ago5 Stars
Truly fantastic. Hydrates even eczema-prone skin exceptionally well, and doesnt have a fragrance which is an added plus.
- MLMelissa L.Verified BuyerRated 5 out of 5 stars5 days agoA little goes a long way
I ordered the customer favorites bundle. Smaller sizes but great to try before you buy the bigger size. I use a small amount on my arms chest and neck. I have since purchased the larger size. My skins looks hydrated and smooth.

- ASAbbie S.Verified BuyerRated 5 out of 5 stars1 week agoGreat after shower before drying
Love to put this on my body before towel drying. Leaves skin hydrated and soft
- DMDarcee M.Verified BuyerRated 4 out of 5 stars1 week agoGreat stuff
I gave it 4 stars because I wish it had the citrus smell so that I could layer it with the oil and lotion.
