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 LOVE this serum!

    Let me start by saying I hate the feeling of lotion on my body. I rarely use the word hate but in this case it applies. For this reason I didn't even plan on trying this serum but my mom gave me some. I am so glad she did!! When I tried it it blew my mind! I use it every day after my shower and I actually look forward to putting it on! My skin feels and looks great. I have fair skin and my chest has burnt a few too many times. Since I started using this serum the skin on my chest has actually healed in ways I thought it never would.

    A super body serum

    I was nervous changing from the body lotion but I am more than happy with the results. I had an accident several years and the skin on my forearm has been rough ever since. After a week of using this product my skin is so soft and looks it!

    Like it but don’t understand it

    If it were. Fragrance free I would like it a lot better.

    I am not sure how to use it.

    Put it on first - then oil?

    Use it instead of oil??

    Not sure what is best way.

    Perfect 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!

    Perfect 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.

    Serum

    Again, a serum leaves a different effect on your maturing skin. It gives you a feeling of plump moisture. Highly recommended.
