    What the gurus are saying

    The 15 different molecular weights of hyaluronic acid deliver exceptional plumping and hydration in a lightweight, non-pilling texture, making this serum feel quite different from standard HA products. It layers seamlessly for twice-daily use without any compromise to other skincare steps. It works best in humid environments, where it gives skin a noticeably plumper, juicier, and more dewy look.

    "The NIOD Multi-Molecular Hyaluronic Complex is an exception to me not really using hyaluronic acid serums, since a lot of my other products already have hyaluronic acid in them, but this one contains fifteen different types of hyaluronic acid. It's actually the serum I use in the summer and not in the winter, because I feel like it performs better when there's more humidity and moisture in the air. It gives more of a plumper look to the skin, makes it look juicy and hydrated, but it's very lightweight, it doesn't pill with other skincare, and it doesn't cause breakouts for me personally even though I'm very acne prone. It's really underrated."

    THE ORDINARY & NIOD APRIL SALE 2026 | TOP 18 ANTI-AGING PRODUCTS + THE PRODUCTS THAT ALWAYS SELL OUT
    "This is their hyaluronic acid serum that contains 15 weights of hyaluronic acids. So, this is not just your basic average hyaluronic acid serum. This contains 15 different types. And so, this is extremely plumping. This is also very hydrating. This penetrates into your skin and plumps up and hydrates those deeper layers of your skin. And it can be used every day, twice a day. I don't generally use hyaluronic acid serums, but this is different and this is an exception. I will incorporate this when I want that plumper, more hydrated look and feel to my skin. This is something that I like to use more during the summer when there's more moisture in the air. It really gives that plumper look and it just looks so youthful and juicy."
    DECIEM SALE 2024 | MUST HAVE PRODUCTS YOU NEED FROM THE ORDINARY, NIOD & LOOPHA - SINCERELY MISS ASH
    "If you use a hyaluronic acid in your everyday routine and you're looking to try something new then I would highly recommend to pick up the NIOD Multi-Molecular Hyaluronic Complex. This is NIOD's version of hyaluronic acid and this contains 15 types of hyaluronic acids. This serum in particular is super plumping and very hydrating on the skin. I like to especially start using this product in the fall and during the winter months because the amount of hydration that this provides my skin is insane. Plus you get this immediate plumping which of course is temporary right but it's nice to have that plumper look to the skin especially for everyday or let's say you have somewhere special to go, use this before you put on your makeup and seal it in with the moisturizer. I like to apply hyaluronic acids on damp skin and then I like to put this all over the face and the neck before this dries up on the skin. You want to put a moisturizer on right away any type of moisturizer to lock in hydration to keep that moisture in the skin to prevent transepidermal water loss but it's also going to give your skin this plump and this rejuvenated look to your skin. It's absolutely amazing. I do like to occasionally use it in let's say the summer months but I like to amp it up during the winter and this is phenomenal. This is a must try and yes I will be picking up another one."

    "This is their hyaluronic acid serum, but this is not a regular basic hyaluronic acid serum. If you love hyaluronic acids, then you have to try this. This is next level because this contains 15 different types, 15 different weights of hyaluronic acids that truly give you deep and surface level hydration. This is also very plumping to the skin as well. So if you love plump skin, hydrated skin, glowy skin, then you are going to absolutely love this. I always love the way that my skin looks and feels. I love this a lot for the winter months because we lack that hydration, we lack glow and plumpness. This can be used everyday twice a day. There's no conflicts with this serum, so you can honestly pair this up with anything and everything. Because it has a watery texture, you want to use this after a facial mist, after an essence or a toner, but before thicker based serums, and of course moisturizer and sunscreen."
    DECIEM SALE 2023 | MUST HAVE PRODUCTS YOU NEED! THE ORDINARY & NIOD SALE
    "If you love your hyaluronic acid serums then you are going to really enjoy the NIOD Multi-Molecular Hyaluronic Complex. This formulation contains 15 types of hyaluronic acids so this is extremely plumping and extremely hydrating and you can use this every day twice a day and you can pair this up with anything as well. When you're using this you want to make sure that you apply this onto damp skin for better absorption and then you want to put your moisturizer on top of this before this dries down because that's how you're going to achieve that plumped look to your skin and your skin is going to stay and feel hydrated for the entire day as well as the entire night. This is fabulous. I like this way better than other hyaluronic acid serums. This is one of my favorites and one of my go-to for that plump look because of those 15 types of hyaluronic acids."

    RATING NIOD'S BEST SELLING SKINCARE | THERE ARE 10 PRODUCTS AND I'VE USED THEM ALL!
    "This is a 10 out of 10 product because it doesn't pill, it is super lightweight, it doesn't have the same texture as your traditional hyaluronic acid serum where it's jelly, where it's thicker and gel like. This is lighter, this is thinner, but it still has a little bit of that thickness to it where it's still moisturizing and it spreads nice and your skin absorbs it. There really isn't any sticky or tackiness with this, there might be a little bit but nothing too crazy. I've never had pilling issues, so this is a product that you could use both morning and night and not have an issue with your layering steps."
    THE ORDINARY & NIOD SALE 2023 | I SPLURGED ONCE AGAIN AND THIS IS WHAT I PURCHASED!
    "I picked up one NIOD Multi-Molecular Hyaluronic Complex so this is their hyaluronic acid serum that contains 15 weights of hyaluronic acids and I really love this serum for that hydrated plumped look. So I just decided to get one because it's not something that I use all the time but if I do want that nice plumped look and to add additional hydration then this is one of my go-tos. If you love your hyaluronic acids I really do recommend this. This is way better than the one from the Ordinary in my opinion."

    "It was the first multimolecular hyaluronic acid I ever fell in love with. It's not sticky. I use it right up and over my eyelids, over my lips, under my fine lines here, right up and around my eyes to prep my eyes for concealer so the concealer doesn't sit in the fine lines."
    ~Nay
    "I don't like the multimolecular hyaluronic acid complex. I just don't think we all need that much hyaluronic acid in our lives. For those of you that do really love your dose of hyaluronic acid this is a great one, but for most of us we get our hyaluronic acid fixed as part of the rest of our skincare routine where it features as an ingredient in just about everything, so that's nothing special."
    ~Mixed
    "The first is the multimolecular hyaluronic acid complex which is a combination of low and high weight hyaluronic acid. The lower weight penetrates a little bit more deeply and the higher weight kind of sits more on the surface of the skin to hydrate."
    ~Yay
    "The Multi-Molecular Hyaluronic Complex is the only thing in here that I really, really, really like. What I would say is, instead of spending 50 dollars on the set, just get the 23 percent off of the Multi-Molecular Hyaluronic Complex."

    What the evidence says.

    Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

    Urea

    Urea both holds water in the skin and gently loosens dead surface cells. At higher strengths it has good evidence for very dry or thickened skin.

    Humectants and emollients

    Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
