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.

The serum works well for dry skin when layered with other moisturizing products. While some note it needs reapplication, most praise its smoothing effects and luxurious feel.

    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.

    I LOVE THIS PRODUCT

    Since starting the use of your products my skin has been baby soft. Also no more saggy creepy arms or inner thighs. I just purchased 2 more bottles of the Hyaluronic Body Serum along with the duo body wash set and 3 piece set that has the body wash, body oil, and body butter. I’m certainly hooked and will be signing up for your subscription. Love, love, love these products.
