The skin is our largest organ. Most of your skin–over 90%–is below the neck. It needs (and deserves) as much attention as your face. Enter Hyaluronic Body Serum, our latest innovation. This ultra-hydrating full body treatment is clinically proven to instantly increase hydration by 161%.* But do you really need a body serum? And how is it different from a lotion, oil, body butter and balm? Read below for everything you need to know about our new body serum and how to use it for visibly healthy, smooth skin.
What Is a Body Serum & Why Do I Need One?
Just like their facial counterparts, body serums are lightweight skincare products designed to deliver high concentrations of active ingredients to the skin. Body serums target specific skin concerns on your body, like dryness, dullness, and skin roughness. Did you know that your body contains fewer sebaceous glands than your face, and therefore doesn’t hydrate itself as effectively? Another fun fact: skin on the body is generally thicker and tends to be less sensitive than your face. This means the skin can withstand more potent doses of active ingredients, and explains why it requires special treatment, especially when it comes to hydration. Applying a hydrating body serum every single day is essential for maintaining the skin’s natural moisture barrier.
Introducing New Wave Hydration
Inspired by our bestselling Hyaluronic Sea Serum for face, our new Hyaluronic Body Serum delivers all of the hydrating properties of our facial serum but is formulated specifically for the skin on your body. This lightweight, fast-absorbing serum is clinically proven to instantly boost hydration and improve the skin’s natural moisture barrier for visibly healthy, smooth skin everywhere. Packed with 5 molecular weights of hyaluronic acid, aloe, vegan peptides and nutrient-dense seaweed, this full-body treatment delivers 24 hours of multi-surface hydration. Even better, it’s dermatologist-tested, works for every skin type (including sensitive) and is completely fragrance free, so it won’t compete with perfume. Our formula feels like a silky-smooth lightweight gel without a sticky or tacky afterfeel. It’s a bit thicker than our hyaluronic face serum, but applied to either damp or dry skin, it absorbs instantly. The results? Soft, smooth, ultra-hydrated skin.

Wondering what makes our body serum so effective? Read on for the naturally-derived ingredients in our formula that make it so unique – and ideal for even the most sensitive skin.
5 Molecular Weights of Hyaluronic Acid
Hyaluronic acid (HA) is a powerful humectant that attracts water and delivers moisture to the skin. Our body serum is formulated with small, medium, and large weights of HA to provide multi-surface layer hydration to the epidermis. The larger molecules sit closer to the skin’s surface to attract water, while medium-sized molecules rejuvenate and visibly plump the skin. The smallest sizes penetrate the skin instantly for deep hydration.
Niacinamide (Vitamin B3)
This powerhouse, multi-tasking ingredient supports the skin barrier, hydrates and visibly smooths the skin.
Vegan Peptides + Green Microalgae
A blend of peptides and sustainably sourced and upcycled microalgae from Iceland hydrates, moisturizes, nourishes and plumps the skin.
Blue-Green Algae
Our sustainable superfood (AKA spirulina) helps replenish essential minerals in the skin.
Aloe
Delivers an immediate boost in hydration and improves skin's moisture barrier.
The Difference Between Body Serums & Body Moisturizers
Quick refresher: Body serums, lotions, butters, balms, and oils are all technically body moisturizers. The real difference is in their texture and skin results. Our Hyaluronic Body Serum is your lightweight, oil free, fast-absorbing go-to, packed with hydrating ingredients like aloe and hyaluronic acid. Body lotions, on the other hand, can be slightly thicker and combine water with moisturizing oils and emollients like glycerin to keep your skin soft and smooth. Then there are body butters and balms, the thickest, most luxurious options, loaded with shea butter and coconut oil for intense moisturization. Last, but not least, there's body oil, which is like a protective shield for your skin. It doesn't contain any water but creates a barrier to lock in moisture and deliver essential nutrients to give you famously glowing skin.
The Best Way to Layer Your Body Serum
Just like with your face serums, Hyaluronic Body Serum is designed to be layered first, followed by your favorite body moisturizer (think lotion, body butter, balm or oil) to maximize results and lock in moisture. However, for some skin types the intense hydration of our Hyaluronic Body Serum may be all you need, especially during the warmer months.
How to Use Hyaluronic Body Serum in a Routine
Our new body serum fits seamlessly into any ritual. Here’s our 3-step guide for smooth, luminous skin.
Step 1: Exfoliate & Cleanse
Exfoliation has the same benefits for the face as for the body: glowing skin and a smoother, more even texture. It also builds an ideal canvas for anything that follows and allows your other skincare products to penetrate better. Start by applying our AHA-infused Undaria Cleansing Body Polish to resurface, cleanse and smooth skin.
Step 2: Treat
Apply our Hyaluronic Body Serum from neck to toes to instantly boost skin’s hydration by 161%.*
Step 3: Moisturize
Finish with our lightweight Undaria Algae™ Body Lotion to lock in moisture and visibly firm skin in just 4 hours.*
