Featured Review

Mind blowing!

"It got rid of my wrinkles on my neck! I should have taken before photos, but I didn’t have much hope as I’ve tried everything to rid my wrinkly neck. On the first use I saw an immediate difference! After one week the wrinkles are almost undetectable! Another staple in my skincare routine!" — Toia J.

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 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.

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.

Yes, 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. It’s also recognized by the National Eczema Association with the Seal of Acceptance™.

However, it's formulated specifically for use on the body and we don’t suggest it 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.

Packaging: Bottle is made of frosted glass and pump is made with 50% PCR (post-consumer recycled) plastic.
Recycling: Remove pump and dispose of it in the trash. Clean bottle and put in your curbside recycling bin*
*Before disposing in your recycling bin, please check if your local curbside recycling program accepts frosted glass.

    In love with the whole line- especially the Serum!

    I decided to go for the impulse buy after the ads kept showing up in my feed. So very glad I did. I had been wanting better body care products for the fall/winter in New England as nothing I’ve tried (and I try a lot) really felt like it had an impact on my skin 10 minutes after applying. I bought a body set and due to promotions received some additional products complementary. I start w shower scrub/cleanser then the serum/lotion or oil! The body butter is killer! The serum goes on like a dream and makes my skin feel amazing ALL day! All the products are outstanding but my favorite is the body serum! They all smell beautiful, light and fresh and natural. I also use top skin lines on my face that I get from my dermatologist and was reluctant to try anything new on my face. But because everything I tried of Osea, I loved- I decided to try the face products that came w the promotion! OMG totally surprised how great the night serum and the atmosphere protectant cream are! I’ve not used long enough for results but the textures /smell are fantastic and my skin feels wonderful!!

    Another note. When I made my first purchase literally 2 days later they started a sale and a promotion of complementary products when you spend a certain amount. Well I did spend that and more. I reached out to the company to see if they would consider adding in the complementary products given the time of my purchase and their promotion. Well they did! I was very impressed! I now use all of their…

    Softening

    I love the serum. I rub it on towel dried skin after a shower. My skin stays soft and hydrated all day. I have fair sensitive skin.

    So hydrating!

    I didn't know what to expect when trying out this product for the first time, but man is it hydrating! I specifically wanted this product because my legs get super dry, and this has definitely helped my skin! I will honestly probably be getting a bigger size soon!

    Mix them together!

    I really like this serum. I like to mix it with the oil while my skin is still moist! Sometimes I spray the hydrating mist on if my skin isn’t wet.
