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.

- JJulieVerified BuyerRated 5 out of 5 stars19 hours agoPerfect Amount of Hydration!
I’m new to body serums but have wanting to take better care of my skin. During the day I’ll use this on my arms to keep them hydrated through the day. At night I’ll use this on my arms and legs with the body balm for a hydration blast!
Photo one is before consistent use of OSEA products second photo is after two months of consistent OSEA use!
- JJulieVerified BuyerRated 5 out of 5 stars19 hours agoPerfect for the Daytime!
I love using this in the morning to give my body (arms and legs) easy hydration to get through the day. At night I'll layer it with the body balm for ultimate hydration effects.

- MKMarthajane K.Verified BuyerRated 5 out of 5 stars2 days agoSerum
Again, a serum leaves a different effect on your maturing skin. It gives you a feeling of plump moisture. Highly recommended.
- SSSally S.Verified BuyerRated 3 out of 5 stars2 days agoWish it lasted longer
I simply cannot afford it because it is used up so quickly. Otherwise it is very nice
- RSRenee S.Verified BuyerRated 5 out of 5 stars4 days agoSo far, so good!
I’m pleased with this product. Age spots on hands and arms are fading! :)
- SMSandra M.Verified BuyerRated 5 out of 5 stars4 days agoAmazing
I love this body serum! My skin looks and feels softer!
- GBGloria B.Verified BuyerRated 3 out of 5 stars4 days agoBody Serum
I could only give 3 stars…I really do like the product and the way it goes on and makes my skin feel. The problem is that it’s only been about a month and it’s more than halfway gone. I don’t even use it everyday!
It’s not cheap and I feel it should last longer. I had the same issue with the body lotion. I like the collagen lotion better and feels it lasts longer than the other and now I am finding the serum also does not last long enough. Perhaps it’s because they are light - I don’t know, but it should last longer!
- JJulieVerified ReviewerRated 5 out of 5 stars5 days agoBEST BODY SERUM EVER!
I’m a huge OSEA fan! Love the body oil and the body butter! This is next level hydration, no sticky, no white residue! I use so frequently a 9oz would ROCK for us die hard fans! We love our grande sizes!
- SCSuzanne C.Verified BuyerRated 5 out of 5 stars1 week agoLove at first try❤️
This is my second bottle and I don’t think I can live without it! I give it as gifts so I can share with those I love, a product I love! Thanks for this serum!
- AGAllyson G.Verified BuyerRated 5 out of 5 stars1 week agoMy favorite thing
This product has changed my crepey skin. It is the most moisturizing and healing product I have ever used on my arms and legs.
