COMPARISON: The best hyaluronic acid serum

Header The Moisturizer - COMPARISON: The best hyaluronic acid serum
Are you looking for a new hyaluronic acid serum? This active is a great way to improve your skin’s hydration and can be easily combined with many other cosmetics. If you want to choose the best among the hyaluronic acid serums from The Ordinary, The Inkey List, Hadalabo, NIOD or Paula’s Choice, read this comparison!


I have been meaning to share this comparison about hyaluronic acid serums with you for a while. In this guide, in which I explained why this is one of the best ingredients that we can use to improve skin hydration, providing an extra water inside and helping to keep it young and firm.

Hyaluronic acid is a very versatile ingredient that helps improve skin hydration and maintain its structure. We can incorporate it interchangeably in our morning and night routines, always after cleaning and keeping the skin moist before applying it (since, if we apply it to dry skin, the result may be opposite to what we are looking for).

Finding your perfect hyaluronic acid serum is not always easy, but after reading this article I am sure you will know which one is the best suit for your skincare needs.

In this post I will speak about these particular products: 

  1. The Ordinary Hyaluronic Acid 2% + B5. 
  2. The Inkey List Hyaluronic Acid. 
  3. Hadalabo Gokujun Premium Hyaluronic Solution.
  4. Hadalabo Advanced Nourish Hyaluron Lotion.
  5. Klairs Rich Moist Soothing Serum.
  6. Medik8 Hydr8 B5.
  7. NIOD Multi-Molecular Hyaluronic Complex (MMHC2).
  8. Paula’s Choice Hyaluronic Acid Booster.
  9. Vichy Mineral 89.
  10. The Chemistry Brand Hyaluronic Concentrate.




I already shared my review of this serum from The Ordinary, which you can read here (LINK). Like most products you can see in this comparison, this serum incorporates panthenol (which provides us with more superficial hydration) in addition to hyaluronic acid (of which we find a 2% concentration).

This serum is one of the most inexpensive ones you can find, making it a good option to start incorporating hyaluronic acid into your routines.

It is a product with a fairly dense texture, and perhaps one of the main disadvantages that I see is the sensation that remains on the skin after applying it, which is sticky and can be uncomfortable in the first uses. In any case, since afterwards you will continue your routine with your moisturizer (and your sunscreen, if you use it in the morning), that feeling is brief and more than bearable.

Aqua (Water), Sodium Hyaluronate, Pentylene Gycol, Propanediol, Sodium Hyaluronate Crosspolymer, Panthenol, Ahnfeltia Concinna Extract, Glycerin, Trisodium Ethylenediamine Disuccinate, Citric Acid, Isoceteth-20, Ethoxydiglycol, Ethylhexylglycerin, Hexylene Glycol, 1.2-Hexanediol, Phenoxyethanol, Caprylyl Glycol.

You can get The Ordinary Hyaluronic Acid 2% + B5 on DECIEM (recommended), on Amazon, on SkinStore and on FeelUnique.



This is another of the economic serums from this comparison and you can also read its full review here. It differs from the previous one in that it does not incorporate panthenol and that, in this case, in addition to sodium hyaluronate, we also find hyaluronic acid itself among the ingredients.

This serum from The Inkey List has a fantastic texture, very light and comfortable to use. In fact it is, so far, one of my favorite hyaluronic acid serums when it comes to sensoriality when applying it. Unlike other hyaluronic acid serums, this one does not leave the sticky feeling that characterizes many.

The results provided by this serum are also very good, helping to improve skin hydration and providing visible results.

Water (Aqua / Eau), Propanediol, Glycerin, Butylene Glycol, Sodium Hyaluronate, Ammonium Acryloyldimethyltaurate/Vp Copolymer, Leuconostoc/Radish Root Ferment Filtrate, Hyaluronic Acid, Carbomer, Polysorbate 20, Palmitoyl Tetrapeptide-7, Palmitoyl Tripeptide-1, Phenoxyethanol.

You can get The Inkey List Hyaluronic Acid on FeelUnique.



This is the best hyaluronic acid serum that I have found so far regarding value for money, since the packaging incorporates much more product than most serums (170 ml vs. 30 ml of a standard serum).

In this case we find a product with various types of hyaluronic acid within its composition to provide us with deep and highly effective hydration. And, indeed, this product does what it promises, as it provides great hydration.

I like to try different hyaluronic acid serums, but this is always a good basic to return to, I totally recommend it.

Water, Butylene Glycol, Glycerin, PPG-10 Methyl Glucose Ether, Hydroxyethyl Urea, Sodium Acetyl Hyaluronate, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hydroxypropyltrimonium Hyaluronate, Sodium Hyaluronate Crosspolymer, Aphanothece Sacrum Exopolysaccharides, Hydrogenated Starch Hydrolysate, Glycosyl Trehalose, Diglycerin, Sorbitol, Pentylene Glycol, Triethyl Citrate, Carbomer, Polyquaternium-51, PEG-32, PEG-75, Ammonium Acrylates Copolymer, Disodium EDTA, Potassium Hydroxide, Diethoxyethyl Succinate, Disodium Succinate, Succinic Acid, Phenoxyethanol, Methylparaben

You can get the Hadalabo Gokujun Premium Hyaluronic Solution on Amazon, and on Yesstyle.



I already had good references for this brand after trying the other Hadalabo serum on this list, and while travelling, I saw the opportunity to try this product, which also incorporates various forms of hyaluronic acid (which facilitates its absorption and effectiveness), I didn’t hesitate.

The texture of this serum is very light, practically watery, but leaves a soft film on the skin that completely disappears after applying the moisturizer. The sensations when using it are very positive, since it provides good hydration in a comfortable and effective way, so I definitely recommend it.

Water, Butylene Gycol, Glycerin, Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Hydrolized Hyaluronic Acid, PPG-10 Methylglucose Ether, Hydroxyethylcellulose, Succynic Acid, Disodium Succinate, Methylparaben.



This is a fairly dense serum and with a more complex composition than others we have seen in the comparison. Specifically, in addition to hyaluronic acid we also find extracts of centella asiatica and licorice, both with soothing properties and a mild derivative of vitamin C (sodium ascorbyl phosphate), which provides us with antioxidants. However, the presence of certain potentially irritating essential oils, such as those of citric origin or lavender, make their composition not among my favorites.

This is a practical serum, since its texture is soft and light (although it is one of the densest I have used) and you can use it in all your morning routines without it being uncomfortable or annoying. You don’t need a lot of product to get effective hydration.

Water, Sodium Hyaluronate, Butylene Glycol, Dimethyl Sulfone, Betaine, Natto Gum, Propanediol, Polyquaternium-51, Disodium EDTA, Centella Asiatica Extract, Glycyrrhiza Glabra (Licorice) Root Extract, Carbomer, Arginine, PEG-60 Hydrogenated Castor Oil, Lysine HCL, Proline, Sodium Ascorbyl Phosphate, Acetyl Methionine, Theanine, Chlorphenesin, Tocopheryl Acetate, Illicium Verum(Anise) Fruit Extract, Citrus Paradisi (Grapefruit) Fruit Extract, Nelumbium Speciosum Flower Extract, Paeonia Suffruticosa Root Extract, Scutellaria Baicalensis Root Extract, Panthenol, Luffa Cylindrica Fruit/Leaf/Stem Extract, Beta-Glucan, Althaea Rosea Flower Extract, Aloe Barbadensis Leaf Extract, Lavandula Angustifolia (Lavender) Oil, Eucalyptus Globulus Leaf Oil, Pelargonium Graveolens Flower Oil, Citrus Limon (Lemon) Peel Oil, Citrus Aurantium Dulcis (Orange) Peel Oil, Cananga Odorata Flower Oil, Portulaca Oleracea Extract, Apium Graveolens (Celery) Extract, Brassica Oleracea Capitata (Cabbage) Leaf Extract, Brassica Oleracea Italica (Broccoli) Extract, Brassica Rapa (Turnip) Leaf Extract, Daucus Carota Sativa (Carrot) Root Extract, Oryza Sativa (Rice) Bran Extract, Solanum Lycopersicum (Tomato) Fruit/Leaf/Stem Extract

You can get the Klairs Rich Moist Soothing Serum on Amazon, on Yesstyle and on Wishtrend.


6. MEDIK8 HYDR8 B5. 

In this case we find a high-end serum. The Medik8 team sent me a mini-size so that I could try it and have a first impression about the product. It is a somewhat thicker serum than others that appear in this same comparison, but it is absorbed very easily and the sticky sensation that characterizes hyaluronic acid when applied is relatively low.

In its composition we can see that the proportion of panthenol is slightly high, and that there is a higher proportion of this ingredient than of sodium hyaluronate itself. In addition, among other ingredients, we can see that it also incorporates various antioxidants, as well as lactic acid. This serum does not include perfumes or essential oils among its ingredients.

I cannot make a full assessment of its effectiveness, as that would require a longer use, but the sensations I had when using it were positive, so now I would like to be able to test the full size and thus have a more global view of the results. that will bring me.

Aqua (Water), Glyceryl Glucoside, Panthenol, Glycerin, Sodium Hyaluronate, Sodium PCA, Urea, Creatine, Allantoin, Diglycerin, Amelanchier Alnifolia (Saskatoon) Fruit Extract, Propylene Glycol, Daucus Carota Sativa (Black Carrot) Juice, Lactic Acid, Hydrolyzed Wheat Protein, Lysine, PCA, Sorbitol, Trehalose, Calcium Pantothenate, Ethylhexylglycerin, Hydroxyacetophenone, Acetyl Glucosamine, Taurine, Glycine Soja (Soybean) Seed Extract, Phenoxyethanol, Lysine HCl, Alanine, Arginine, Histidine HCl, Serine, Proline, Glutamic Acid, Threonine, Valine, Leucine, Glycine, Isoleucine, Phenylalanine, Potassium Sorbate, Sodium Benzoate, Citric Acid.

You can get the Medik8 Hydr8 B5 serum on Amazon and on FeelUnique.



This NIOD serum is probably one of the lightest products that you will find in this comparison. Its texture is very, very watery and it gets applied very comfortably, absorbing quickly.

Among its ingredients we find three forms of hyaluronic acid (including pure hyaluronic acid), in addition to other compounds that help improve skin hydration, providing the water it needs to stay healthy and balanced in the short, medium and long term.

Aqua (Water), Hydrolyzed Yeast Extract, Glycerin, Hyaluronic Acid, Sodium Hyaluronate, Sodium Butyroyl Hyaluronate, Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, Disodium Acetyl Glucosamine Phosphate, Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate, Pseudoalteromonas Exopolysaccharides, Tamarindus Indica Seed Gum, Tremella Fuciformis Sporocarp Extract, Ceratonia Siliqua Gum, Myristoyl Nonapeptide-3, Plantago Lanceolata Leaf Extract, Salvia Sclarea Extract, Arginine, Aspartic Acid, Glycine, Alanine, Serine, Valine, Isoleucine, Proline, Threonine, Histidine, Phenylalanine, PCA, Sodium PCA, Betaine, Sodium Lactate, Epigallocatechin Gallatyl Glucoside, Gallyl Glucoside, Algae Extract, Sodium Salicylate, Lecithin, Polyglucuronic Acid, Xanthan Gum, Trisodium Ethylenediamine Disuccinate, Sclerotium Gum, Pullulan, Cetyl Hydroxyethylcellulose, Propanediol, Pentylene Glycol, Dimethyl Isosorbide, Citric Acid, Magnesium Chloride, Silica, Polysorbate 20, Ethoxydiglycol, Propyl Gallate, Dehydroacetic Acid, Benzyl Alcohol, Potassium Sorbate, Sodium Benzoate, Ethylhexylglycerin, 1,2-Hexanediol, Caprylyl Glycol, Phenoxyethanol.

You can get the NIOD Multi-Molecular Hyaluronic Complex (MMHC2) on DECIEM (recommended), on SkinStore, on Amazon and on FeelUnique.



You know that Paula’s Choice is one of my reference brands, they develop very effective products and they have an immense range, which allows us to find something that fits the different types of needs that our skin may have.

In this case, they have developed a serum that includes hyaluronic acid, sodium hyaluronate and ceramides among its ingredients, helping us through immense hydration to the skin while keeping our hydrolipidic barrier protected.

The sensations when applying the product are positive, it is not sticky at all and its texture is slightly dense but well balanced. Perhaps, if you are looking for a more advanced product that provides your skin with more than just hyaluronic acid, it may be a suitable option for you. If what you are looking for is a simpler product, there are other ones you may prefer in this same comparison.

Water (Aqua), Glycerin (hydration/skin replenishing), Sodium Hyaluronate (hydration/skin replenishing), Hyaluronic Acid (hydration/skin replenishing), Ceramide NP (hydration/skin replenishing), Ceramide AP (hydration/skin replenishing), Ceramide EOP (hydration/skin replenishing), Phytosphingosine (hydration/skin replenishing), Yeast Extract (skin replenishing), Adenosine (skin-restoring), Cholesterol (skin replenishing), Panthenol (skin replenishing), Silanetriol (hydration), Butylene Glycol (hydration), Sodium Lauroyl Lactylate (hydration), Carbomer (texture-enhancing), Xanthan Gum (texture-enhancing), Citric Acid, Sodium Hydroxide, Polysorbate 20 (texture-enhancing), Ethylhexylglycerin (preservative), Phenoxyethanol (preservative).

You can get the Paula’s Choice Hyaluronic Acid Booster on Paula’s Choice, on Amazon and on Niche Beauty.



The composition of this serum seems to me excessively simple, and in terms of value for money I think it is one of the worst ones in this comparison. From the brand they already report that 89% of its composition is water. I understand that it is the base of infinity of products, since it is a very cheap excipient, but using it as a claim seems quite striking to me.

As for ingredients designed to improve skin hydration, the most prominent presence we find is sodium hyaluronate. Its texture is very light, more watery than in most serums of this type, so that absorption is practically instantaneous.

I had very high expectations with this serum and I admit that it did not perform as well as I expected. It is possible that, if you have tried more products of this type, you’ll have higher standards and therefore you’ll aim for deep hydration, so I think I would opt for other serums that I have incorporated into this comparison before this one.

Aqua / Water, PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin, Glycerin, Butylene Glycol, Methyl Gluceth-20, Carbomer, Sodium Hyaluronate, Phenoxyethanol, Caprylyl Glycol, Citric Acid, Biosaccharide Gum-1.

You can get the Vichy Mineral 89 serum on Amazon and on FeelUnique.



This is quite a particular one, and that’s because this hyaluronic acid concentrate was designed to be used all over the body. When we talk about cosmetics we often think exclusively of those that we apply on the face, but we must remember to protect and pamper all our skin.

In this case, in addition to hyaluronic acid, DECIEM have incorporated other ingredients with important moisturizing properties, such as tamarind and tremella fuciformis sporocarp extract. This combination of ingredients provides us with a very deep hydration, helping us to keep all our skin cared for.

The results provided by this product are fantastic. I like to apply it on wet skin after showering, then apply my moisturizer. It is most effective, as you extend it you can appreciate how the water from the surface of the skin gets absorbed, clearly showing its results.

Aqua (Water), Sodium Hyaluronate Crosspolymer, Tamarindus Indica Seed Gum, Tremella Fuciformis Sporocarp Extract, Ahnfeltia Concinna Extract, Glycerin, Pentylene Glycol, Betaine, Carbomer, Triethanolamine, Potassium Sorbate, Ethylhexylglycerin, Hexylene Glycol, Caprylyl Glycol, Phenoxyethanol, Chlorphenesin. 

You can get The Chemistry Brand Hyaluronic Concentrate on DECIEM (recommended) and on Amazon.

    Great post. I was looking for comparison between Vichy and NIOD. Your post helped me make up my mind. Thanks for providing us with the valuable info and saving our money lol.

  2. El

    awful post! how is this is a comparison? you are not comparing anything, simply just listing a description and where to buy – all this information i can find already on their own websites. waste of post and time.

  3. WONG

    hi Thanks for your kindly sharing. i suggest you put small product photos next to the product name that you recommanded. Just a little comment

    • Nacho · The Moisturizer

      Hi Wong! 😊

      Thanks a lot for the suggestion, it’s something I’ve had in my to-do list for a while (since creating a website and its content takes so much time and it’s not always easy to get everything done as quickly as I’d wish), but I’ll be sure to include those pictures someday 😉

      Have a great day,
