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.

    Review on sample size

    I can’t really give a positive review due to it being a sample bottle with a small bottle I don’t think it’s enough to determine if it works, no complaints on the smell or how it feels.

    Love this Body Serum

    I love the silky feel of this body serum. I live in climate that is very dry year-round and the extra boost of hydration this serum provides has really made a difference for my skin. I would love to see this available in a larger bottle :-)

    Funny smell

    The first serum I ordered was wonderful. However this time it has a funny smell. Can’t really tolerate it on my face.

    Bestt product ever!!!

    I absolutely love this skin serum. I have sensitive skin and do not like the feeling of oils. This absorbs quickly and leaves skin feeling velvety. Osea, can you please make it in a jumbo size???
