SKU: 5060422297032 Categories: , Brand:


Naturally found in the skin to maintain hydration, Hyaluronic Acid levels gradually reduce over time which can result in dullness, fine lines and uneven tone and texture. Hyaluronic Acid works as a magnet for moisture, helping your cells retain as much of it as possible so that your skin feels and appears hydrated, plump and healthy.

Hyaluronic acid acts to:

  • Target dry skin
  • Works to hydrate skin
  • Reduce the appearance of wrinkles
  • Reduce the appearance of fine lines


  • 2% Pure Hyaluronic Acid
  • Low and high molecular weight, to ensure penetration beneath the skin surface for maximum hydration
  • Matrixyl 3000 to aid collagen production for added plumping effect
  • Ideal for all skin types

Use morning and evening. Apply a pea-sized amount to cleansed skin and pat gently. Can be used together with other serums. Follow with moisturiser.

  1. Ayden

    I love this serum, it helped me retain moisture for my skin, results aren’t automatic but gradual. I would recommend

  2. Sofie

    I really like this product. It does what it promises, and hydrates my dry skin really nicely! I wish it came in a dispenser with a pump but for the price it is just fine.

  3. Cris

    I’m very pleased with this product, absorb quickly, and after a month, my skin looks moist and fresh than before.

  4. Natalie

    I am now on my second bottle of this amazing serum. I didn’t think it would last me that long but the bottle is deceiving, Using every day, sometimes twice a day, this lasted me about 3 months! I mix this with my Vitamin C every morning and it leaves my skin so plump and hydrated, there is no tacky or sticky residue left on the skin either which is hard to find in a hyaluronic! I have tried so many other products like this that I love, but the price, packaging and results from this really are amazing!

  5. Sirin

    Firstly I really hate the packaging, it’s hard to use and to estimate quantity. I prefer the dropper like The Ordinary much more. Please change the packaging if you can. I live in humidity and a hot area so this is not my cup of tea as it leaves my skin oily. I like to mix it in with my moisturiser.

  6. Maryam

    A steal for the price. 4 months later it is still going strong. The bottle is tiny but don’t let it deceive you. Smell is a tad acidic but absorbs fast. Not sticky. Will purchase again.

    I have several Hyaluronic Acids in my collection as it really is a savior for my oily complexion. There’s no escaping the benefits of hyaluronic acid and I’m sure everyone has heard that “it holds 1000 times its weight in water” but this truly does help all complexions. For people with dry skin, this is going to help attract moisture to hydrate but for those with oily complexions, the water magnet also helps keep the skin hydrated preventing it from overproducing oil. This particular serum contains different molecular sizes of HA and has a great texture and absorbs nicely into the skin and doesn’t ball up on the skin like others on the market.

  8. Finley

    I bought this product recently and love the actual serum. Smooth, easy to apply and a little goes a long way. Both my 20 something daughter and my 50+ self are really impressed with the formula. No pilling under other products and make-up. The only thing I don’t like is the packaging. The other hyaluronic acids I’ve used – including high end and budget versions – use a dropper, which is much easier to ensure dispensing the required amount. Hasn’t put me off ordering again though. It’s a quality product at about a sixth of the price of my previous favourite.

  9. Clara

    The packaging is bad, tbh, it feels cheap and it gives you too much product. A dripper would have been so much better, and since The Ordinary carry basically the same product for the same price, but better packaged I prefer theirs. Also, it has a smell, and I don’t see that much of a difference.

  10. CleanJunkie

    I used this once and woke up with a very oily face with red blotches around the cheeks. Never experienced this before. They did go down later and my skin was fine and quite plump but not sure I like the oilyness

  11. Bellis

    I’ve used a few different hyaluronic serums, and this one is brilliant. It hydrates my dehydrated 40+ year old caucasian skin, and sits nicely under my other skin care and make-up. The price is incredible, and it doesn’t come with a side order of drama from the company’s founders. There is nothing I dislike about it, and I’ll be checking out other products from the brand on the basis of my experience with this serum.

  12. Lizzie

    My 1st time ever using HA after a time of searching and reading review. I purchased along with Herbivore facial oil and they together make my skin plumps, glowing and moisturized all the time during this dry autumn and winter yet it ‘s running out quite quickly. Even noticed smaller pore around my nose – best thing ever happen and balanced complexion, now I’m so pleased just looking at my skin. Already do the WOM to my friends and they ask me to buy for them if I restock this gem

  13. Ivy

    I have used this serum for six months (face + neck) as a part of my day-time regime. Currently, I’m on my 6th bottle. I have a combination skin with rosacea and in my case this serum functions very good. It moisturizes skin without any irritation.
    The price of this product is very fair! I will use it again and again!

  14. coco

    I love this, it’s a breakthrough, my skin is absolutely perfect after using it. Plumps up and hydrates, what more does a girl want

  15. CHM

    I’ve used the Inkey List hyaluronic acid both morning and night for well over a year now and find that it gives slight plumpness to my skin and leaves it feeling much more hydrated. My moisturiser and foundation go on smoothly after it. Pleasant to use and a small amount goes a long way so it’s value for money. I’d certainly recommend this product.

  16. Syhem

    I always include HA in my routine, but finding a serum that is not sticky is not easy! This one really surprised me as the texture is super light and it absorbs quickly. When I’m in a rush I mix it in my moisturiser (Protini – DE) and I’m ready to go for the day!

  17. Gigi

    I use it every day!
    I’m on the 2nd bottle and I will buy more!
    It’s amazing, super affordable, and does what it claims.
    I absolutely love it!

  18. Louise

    The serum itself is lovely and simple, an easy way to get Hyaluronic Acid in the routine, but the bottle is impossible – always end up with too much product to use as the lid mechanism causes a small vacuum and then suddenly half the bottle contents in my hand!

  19. Danica

    I have dry skin and a combination, sometimes my skin decides to do its own thing but this is a constant through it all. As a full time buyer of skin care products this really does take care of my skin. I haven’t seen it glow this much since forever so I’m really satisfied with it .

  20. Helena

    Probably just me being unlucky. Ordered this and the Q10. Both leaked terribly and soaked through its paper box. I’ve ordered stuff from the inkey list from ASOS before and didn’t arrive in a wet box!

  21. Yasmin

    I apply a pea-sized amount to my face before bed and I wake up to refreshed, plump and hydrated skin. My fine lines are smoothed out and my skin looks even in tone. Absolutely stellar product and for such a wonderfully small price.

  22. Adene

    The fluid feel of this product is fantastic ~ no sticky or tacky feel to it. A little goes a long way with this product ~ more than a pea sized amount patted into the skin will not provide more hydrating benefits ~ stick to the pea sized amount for the perfect hydration boost.

  23. AimeeDee

    Always the first step in skincare after cleansing and toning to ready my skin for a more specific treatment. You’ll notice a difference in a week. Excellent stuff!

  24. Theodora

    I have bought it for my mother and the difference can be seen clearly as her face is smoother and shinier. ❤️ She is very happy with it and I will surely buy it again really soon. 5/5 ⭐

  25. IA

    So easy to add into daily routine. I use this with Vitamin C in the evening and underneath my moisturiser in the mornings. Sinks straight into the skin with no residue. Great value for money.

  26. Moogie

    Finally found a HA that is not horrendously tacky after application! All HA’s will be a little, but this one sinks into the skin wonderfully and compliments the other steps in my routine so well. My skin looks plump and glowing from within without that greasy film some products can leave, would recommend

  27. Polished by Leanne

    Absolutely love this product, the price is right, it’s instantly effective and a complete must have for those with dry/dehydrated skin. Brilliant!

  28. Amanda

    I never used serums until recommended to me and it didn’t disappoint. I found it was a bit sticky at first, but then within about 15 minutes, my skin felt SO soft and hydrated. I just wish The Inkey List made bigger bottles of this stuff!!!

  29. moo

    I am in love with this stuff and get nervous when I run low. Forever I have been stuck with bad skin and trying everything under the sun never works, I even had a bad reaction to The Ordinary products so thought I would never get rid of the spots. This stuff has cleared my skin so much and given it a lovely glow (in conjunction with other Inkey products). My skin feels plumped and makeup sits so much better. I have just run out and I am about to buy 2 more.

  30. Claire

    Use it underneath other products day and night, absorbs so nicely & has made a real difference to my skin, both texture and glow

  31. Angie

    One of the best HA I have ever tried and the price is super!
    4 in my rate is because I would like to be in a bottle with a dropper. But i bought it for second time because it does what it promises and it felt like a film which secures the moisture on my skin. Good job Inkey list!

  32. Rosen

    I have used this for a week now and can really see a difference. I live in a cold climate and I have sensitive skin. I use this in combination with one of their oils and my skin feels hydrated all day long. It gets 4/5 due to I haven’t used this type of serum before so I have no reference to compare.

  33. Aris

    All my family members have a bottle at home, that’s how amazing this product is! You may not see results in a day or a week but continuous use can make a huge difference! I’m 21 and am experiencing some hormonal acnes, what HA does is it helps my other serums to absorb better into my skin and calms my acne down. This HA absorbs really quickly too, so there is no sticky feeling left on the skin! Will definitely re-purchase!

  34. Beth

    This HA is lovely, works really well! Especially for the price. The packaging annoys me, and wish it was a dropper bottle. The liquid isn’t sticky when applied to skin and absorbs really quickly. Nicely hydrating

  35. MoorMaiden

    I received this product less than 24 hours ago, have used it twice (at bedtime and the next morning) and am noticing IMMEDIATE improvement in the fine lines, moisture level, and general plumpiness of my skin. This liquid serum is fragrance free, goes on extremely smooth, and has truly done what it says it will just about instantly. Definitely looking forward to continued use and even better results. I also have sensitive skin, and other products have bothered me in the past … not so with this one. Incidentally, I purchased a few other products from this line at the same time as this, and will be reviewing them similarly – each of them is making a noticeable, instant improvement in my skin!

  36. Khanya N.

    I absolutely love this product. I was using it at a time when the area around my mouth started feeling very dry and sensitive, and this helped that in a way my other HA serums didn’t. Love the texture of it – not too thick but not too watery either. The only thing I would change is the packaging; I would prefer a dropper bottle because that would help me control how much product comes out, because with the current bottle it’s very easy to get more than you wanted. Otherwise, love this product and will definitely be repurchasing.

  37. Pauls

    I really love the quality of this brand, the products are good and perform. The packaging is problematic and can become an expense, please do something about it! Each and every single time I receive my orders there are a few products that leaked – this packaging is not secure and causes spillage which rather adds up after a few purchases because it happens every single time. This could also comprise the product quality and longevity / affect expiry as it’s NOT sealed. Certainly I’m not the only one experiencing and complaining about this issue? I hope the brand takes note; the packaging is not secure – please consider changing the cap or sealing the bottle below the cap to seal the product in fresh.

  38. My Risum

    It is honestly just as good as hydrating serums A LOT more expensive, holy grail in my routine.

  39. Winnie

    I noticed a slight difference in the plumpness of my skin and would recommend anyone to give this product a go. At this price, you can’t go wrong.

  40. Olivia

    I used this the first time this morning and my skin has looked hydrated & plump all day! I have very dry skin and for my skin to look the way it does 8 hours after applying skincare is unreal, I’d normally have to reapply with oil and use a hydrating mist a few times. It’s now a staple in my routine and the price is an added bonus.

  41. Salsa

    I have sensitive and combination skin and this product did not irritate my face. The only problem is that when I use it, I feel my face is a little bit sticky (in the first minute) and because of that I gave this product 4 star.

  42. Cachou

    My skin texture has changed from the third day and people have noticed it. I ordered 3 more bottles.

  43. JulesyG

    I love this. I couldn’t be without it. I use it followed by Buffet by The Ordinary and I find the combination so hydrating and I can really see the difference in my skin. I use it AM and PM as soon as I’ve cleansed.

  44. Bev

    Having tried many formulations and brands of HA, I can honestly say this is by far my favourite- no stickiness, no residue, no pilling, no tightness or drying after-effects and a plumped and glowing complexion after just one use. This product is fantastic, my only wish is that it came in a larger size because I literally cannot live without it! Thank you @Theinkeylist!

  45. Plastic fantastic

    Simple, uncomplicated. A great quality, super reasonable hyaluronic perfect for a daily dose of hydration. An absolute essential. Locks in and attracts moisture to keep your skin super plump and refined. A tad less sticky than some others but a layer of any moisturiser over top will eliminate any stickyness. I recommend mixing 2 drops or so of this with either the inkey list heptapeptide, or the ordinary buffet for a complete daily hydration shot supercharged with anti ageing peptides. A simple moisturiser to finish and you’re all set!

  46. amo

    It’s a very good serum.
    I have mature, really dry skin.
    I mix it with a moisturizer.
    Although I prefer Barbara Sturm hyaluronic serum, this one the difference in price makes it worth to buy this one.
    Skin plumped and hydrated.

  47. Mel

    I’ve tried a number of hyaluronic acids ranging from The Ordinary to Dr Barbara Sturm and this is my all time favourite! The texture is light and doesn’t leave you sticky (which I find happens with The Ordinary one) and sinks in fast (but doesn’t leave me feeling dry like the Barbara Sturm). The price is an added bonus – absolutely can’t go wrong!

  48. Method

    Make my skin more relaxed and reduces fine lines.

  49. channy

    Not too sure what people are talking about with the packaging? I’ve had three now and never had an issue? I’ve tried so many ha acid serums both expensive and cheaper and this has shown to be the most effective. I’ve even had dermatologists look at it and give it a good rating. Soooo I love it, will be a forever purchase

  50. Emilia

    This hyaluronic acid instantly plumps with hydration.

  51. Chrissi

    This is my first bottle of this HA serum but I don’t think it will be my last! My skin loves it and I’m rewarded with plump, super-hydrated skin. Sometimes I cocktail with The Inkey’s Collagen or Q10 serums and find that this works well too. Brilliant serum at a brilliant price. Thank you!

  52. Alexandra

    I have had good experiences from The Ordinary’s HA serum and expected this to be similar. Not so much… not very hydrating and oddly making my skin react a little bit. It was not for me.

  53. Kinga

    I suffer from rosacea and I really need to watch what I’m using because my red cheeks are extremely reactive… This serum is lovely. No irritation, nothing… I use it just overnight and it’s lovely. My skin really likes it 🙂

  54. Abby

    I normally steer clear of products like this as I have oily and acne prone skin, but this has really helped my skin. It makes your skin look plump (like you’ve had 8 glasses of water), and helps with any dryness from acne medication. So easy to use, and works well with all of my other products.

  55. Boglarka

    I’ve been experimenting with different skincare lines in the past years, considering Deciem brands my ultimate holy grails up to now. I still adore those products, however, after using up my old The Ordinary Hyaluronic Acid, I was looking for a great AM serum that doesn’t make me oily but neither makes my combo skin dehydrated. I purchased this Hyaluronic Acid Serum together with the Q10 Serum from The Inkey List and I LOVE them combined as part of my morning and evening routine as well. After cleansing, I use this and follow with the Q10, everything else in my morning routine stayed the same. I swear I already noticed a huge difference on the first day. My skin looks so much more plumped and balanced, that usual oiliness didn’t happen at all. This serum is also incredibly lightweight and not sticky like the one by The Ordinary. I’m so happy with my purchase!

  56. Sabrina

    Loving this product!

  57. Yara

    I love it! After trying this serum I found it not sticky & it absorbs quickly. Will be repurchasing in the future.

  58. Cloé H.

    This is a good product and if you’re on the hunt for a cheap HA serum, this will certainly do! However, for a rather similar price point, I find the Hylamide HA serum to be more effective, for example.

  59. Kim

    This hyaluronic acid instantly plumps with hydration. I apply and let set for several minutes (as it is slightly sticky on application), once it is set, it absorbs a ton of moisturiser so my skin feels truly hydrated. And it’s a fiver!!

  60. mel

    Not much impressed I would rather pick a hydrating mist for my combo skin. But for someone with drier skin it might work. But much affordable than other ha serums.
