Most Helpful Positive

Smooths skin over instantly


I love this serum it is very lightweight and effective, after it dries down for a few minutes the skin is noticeably more smooth and lines are slightly filled in a bit more. I use this in conjunction with niacinamide to keep my oily skin hydrated and it works well. I also mix it in with vitamin c of a morning as a pre moisturiser, before sunscreen which helps keep me hydrated but not oily.

Most Helpful Criticism

Not a bad moisturizer


I bought this on the back of the great experience I had with the buffet and HA.
This isn't the most hydrating moisturizer I've used, but it wasn't the worst. It left my skin feeling soft, but not very "hydrated". I think works better if you apply a serum before hand.
  1. It's ok


    I have been using this for two months now, and it's ok. It adds a little hydration to the skin, and I think it improves the effectiveness of my moisturiser, but overall I think this is the least effective product in my skincare routine. I will finish the bottle because it's not bad but probably won't repurchase.
  2. Good Application


    The first use of this product Had a great skin feel. The dropper applicator was great. At first I was concerned about the 30ml size but can now see it will last a long time which will work GREAT for the price! The serum is easy to move around but still thick enough to get the job done.


    given the price you pay for, i think its pretty good.
    but im taken back by its sticky texture, when you put on the face, its not very smooth at all.
    so i have been using this under my mask as a first step of my hydrating routine...not under my moisturiser coz too sticky.

  5. Super helpful


    This was my first time using a Hyaluronic acid and I'm so happy with it! It's so affordable and really hydrates my dry skin. I use it morning and night on damp skin and can definitely feel my face is more hydrated and soft. I even used it on my hands!
  6. Spot on!


    Originally I was dubious of hyaluronic acid and the strength, but even after one use I can feel it assists with hydration on my super dry skin! Definitely follow the 'few drops' advisement!
  7. OK


    Key things to remember when using this product is to wet your face beforehand, otherwise, it will overly dry your skin. It's an ok product, what you pay for is what you get. I don't see the huge hype around it unfortunately.
  8. My holy grail


    My skin use to be so dull, but ever since using this product I've noticed such a difference! it makes my face feel so plump and have such a natural glow to it, don't think I can ever go back.
  9. Makes you Glow


    Overall, I did really like this product for its intense glow that it gave me. I used this on wet skin and followed with moisturiser. I had gotten so many compliments on how much my skin was glowing from family and friends at school, I was pleasantly surprised! however, it hasn't helped much with my acne or hyper-pigmentation. I will continue to use it as i have heard you should be a bit patient...

  10. Great for moisture


    I use this serum in the morning and have noticed it keeps my skin much more hydrated. I like to mix mine with vitamin C powder and the two together have made my skin really glowy.
  11. Good hydration


    It’s a good product for the price but not as hydrating as the Alpha-H one. I will definitely go back to Alpha-H
  12. I love HA and I love this serum


    Go no further if you're looking for hydrated skin. This stuff is like gold for your skin. I use this every morning to keep my skin feeling hydrated and fresh all day. Love love love.
  13. Love this product


    I love this product!! My skin has never looked / felt better and after the first day of using it I had noticed a difference in my skin tone. I love how affordable the ordinary products are. Very happy with my purchase! ❤️
  14. Pretty good


    The first couple times this dried out my skin rather than hydrate but i realised its because i didnt know how to use it (use on damp skin people!) But after that i do feel like it has hydrated my skin and my skin is looking brighter and more plump and less dull than before. Definitely worth a try :)
  15. Hydrating


    Feels really nice and hydrating after application , makes skin feeling soft and smooth day after
  16. The best moisture on a budget!


    This stuff is the bees knees! My skin is plumper and makeup sits on it so much better. I would have a bath in it if I could and at the price I have already purchased the supersizes bottle as well.
  17. Great for body!


    I didn’t like this on my face, so now I use it on my body under a heavier moisturiser to give that extra hydration boost in winter.
  18. Affordable and works!


    Great product with a great price tag. Absolute staple for my dry skin. Great for layer with my retinol!
  19. Hydrating


    A cup of water for your skin. Good for all types of skin :)
  20. Try it on damp skin!


    I love this but find it pills when I use something over the top. I recently found out that you can apply it to damp skin and this eliminates the problem completely!
  21. enjoy


    cant go past the price. definitely follow with moisuturiser for full effect
  22. Amazing Hydration


    Amazing product, tried a year ago and haven’t been able to put it down since, defiantly worth the purchase
  23. Dry skin's best friend


    I have always been troubled with dry and patchy skin. This product is my saviour! It's a lightweight serum that seeps into skin quickly and provides hydration throughout the day!
  24. Good starting point


    After hearing so much about Hyaluronic Acid I thought I would add this into my morning routine. I heard that it gives a plumping effect. Not sure if it does this but it certainly gives some extra hydration.
    Its a nice texture and spreads well. I have been using this for a month - I don't think I will re-purchase at this stage despite how great the price is.
  25. Effective & wallet friendly


    I've been using this product for 2 months now and I saw a visible difference in my skin's hydration within the first few days. Super effective for the price compared to other HA products out there. It's a staple in my skincare routine now. Very happy with it!
  26. Refreshing


    The texture of this product is very wet but it feels hydrating on the skin! Make sure that you have a wet face before applying this product to get the best results. Overall I was happy with this product but it wasn’t as good as I was expecting. I will keep using it and updating you on any changes to me skin
  27. Holy grail


    with use of actives my skin gets very dry and this the only product which really worked on my skin and make it plumpier and hydrated
  28. super hydrating


    feels amazing on my skin and helped keep my face hydrated, absolutely love it!
  29. Good hydration but goes flakey on my skin


    This adds good hydration to my skin but can sometimes go flakey on my face when it dries which is annoying (not sure how it’d go under make up!). If I wet my face before applying it seems to help though. The product absorbs quickly but is stickier than I was expecting
  30. Great product


    I use this first thing in the morning and I feel like it instantly brightens my skin and preps it for makeup. Love it!
  31. Love this one


    I've been through 3 bottles of this stuff already, at least.

    Tip: Apply when face is still damp or mix it with a moisturizer and apply that way.
    When I first got it I'd apply it alone to a dry face and found it felt sticky and my makeup would pill over top of this product. That stopped happening when I changed how I applied it!

    I kept hearing 'HA' + 'hyaloronic a...

  32. Best Hyaluronic Acid Serum


    This is the best hyaluronic acid serum that I have ever used! I love how basic the ingredient list is, what is stated on the bottle is exactly what is in the serum and no unnecessary nasty ingredients.
  33. sooo good


    Didn't expect it to work as I have notoriously sensitive and dry skin with recurring eczema. My face has never looked more hydrated and I used this bottle 2x a day for 2 months!
  34. Very hydrating


    I used this product when my skin was still damp and I love it! It works well with all the other products in my skin care routine.

  36. Great hyaluronic acid


    I love this hyaluronic acid, it absorbs quickly into the skin and feels good layering with Niacinamide, etc. with a moisturizer on top. While using this product, my skin has noticeably been more hydrated. My only issue is the sticky feel of this product, but that wouldn't stop me from repurchasing or recommending to a friend! Definitely worth a try
  37. Gentle


    This is a great product I use it in the day and spritz before and after. My skin feels more hydrated and smooth. I will purchase again
  38. Super plumping


    This is my first hyaluronic serum and I'm digging it. As soon as I apply it, my skin plumps up and I can see my frown lines get visibly less prominent. My only complaint is the stickiness it leaves on skin - however, after using damp hands to apply it, the stickiness somewhat lessens. For the price point though you really can't expect much more, it's a great product.
  39. Super moisturising


    I love this product!! I have combo skin and this moisturises without leaving my skin oily or wet looking. Super easy to use with other products
  40. Great basic serum


    This product is consistent in feel and texture to other hyaluronic acid serums that I've used in the past, the difference is the great price and the addition of the B5. I think people might be surprised that this serum isn't creamy and doesn't feel overly nourishing (I am middle aged), but that's normal and I use it as part of a layering beauty routine morning and night (with an acid serum, eye cr...

  41. Brilliant product


    The Ordinary really delivers in terms of super active goodness for the skin at a budget friendly price
    Lovely consistency and absorption. Skin was definitely plumper and surface dehydrated eliminated. Highly recommend!
  42. A little on the sticky side


    Does the job of hydrating your skin however I don't love the sticky feeling when you apply it on its own. I also find it takes a little longer to sink in than some of my other serums. Thus I sometimes add this serum to my other products like my moisturiser to lessen the sticky feeling.
  43. Love this!!


    I use as a nightly moisturiser after I do light skin needling, it's perfect for that!
  44. Skin plumping


    Plumps my skin up really nicely- especially after a facial steam. However, it is a little sticky, so I usually mix with other products rather than using it on it's own.
  45. best skincare routine



    I am new to the ordinary skincare regime, I have oily acne prone scarred skin, so far I have bought
    Niacinamide, hyloronic acid, granactive retinoid 5%,sallycillic acid face mask, and natural moisturising factor

  46. amazing


    This is so cheap and just as good as other hyaluronic acids from other brands. I compared the Medik8 Hyaluronic acid with this and T.O acid is thicker and gives just as good results. But beware, this product only works if there is moisture already present (in air or on skin) so I apply it after a steamy shower or after putting small water droplets on my face - otherwise it can actually dry your sk...

  47. Do i like?


    It's my first time trying hyaluronic acid, I am enjoying it but I don't love the stickiness of it. It absorbs really well though. I've used it for a few weeks now and I have seen improvements but I'm still unsure if its something I will buy again.
  48. Hydration heaven


    I’ve tried more expensive hyaluronic acids - this one is my favourite! I apply before moisturising every night - my skin feels plump and hydrated in the morning. An essential part of my skincare routine - which will continue for years to come. I even bought one for my mum
  49. Get it, girl


    Absolutely love this product... I have been using this in the AM & PM and have noticed some amazing results. My skin feels very hydrated and plump 24/7... I will defs have this in my skin routine for years to come!
  50. Super-hydrating serum


    I've been really happy with this serum from The Ordinary. It applies beautifully, is light-weight and not oily. A great price too.

  51. Plump and Glowy


    At first I was really confused by this product and where to add it into my routine, it created tacky buildups on my face when l layered any water/oil based products on top. My normal combination skin reacts well to this when I keep the routine fairly basic (cleanse, serum, niacinimide, HA and moisturiser). My skin gets a dewy glow that leaves the texture looking nice and plump. Fantastic buy for t...

  52. Plump me up, buttercup!


    I've had my eye on The Ordinary for a while - sleek packaging, GREAT price point - but I was intimidated because the fancy-pants science-y names meant I didn't really know what to get to or where to start, let alone how to effectively use the products. Also have sensitive skin and have spent lots of $$$ on products only to find I reacted or didn't get the results I wanted. I really didn't want tha...

  53. Super plumping!


    I've been using this product for over a month and have noticed a significant difference in the plumpness of my skin. My skin definitely feels more hydrated and bouncier since I've started using this.

    I would definitely recommend this product!!
  54. nice HA


    although it's a kind of sticky texture, i really like the effect on my skin. my skin feels smooth and hydrated. i just need a 2 little drops to go on all my face. very affordable product
  55. Hydrating


    A super affordable and effective serum. I use after a spraying toner so my face is damp and then I lock it all in with moisturiser! I feel that it absorbs into my skin much more when it's damp compared to when used on dry skin. Leaves my skin feeling hydrated and plump all day long. Love the cheap price point and would recommend because it does what it says!
  56. Super hydrating serum


    Who says good skincare needs to be expensive? The Ordinary Hyaluronic Acid 2% + B5 is super easy on my sensitive skin and noticeably hydrates. It's easy to incorporate into your skincare routine and great value for money!
    Only thing i have noticed is the product can build up when combined with a Face Oil, so I have starting leaving a couple of minute between each step.
  57. Sensitive Skin - Rosacea


    I am 23 years old I have done a LOT of research on the best items for my skincare routine because I have Rosacea and dark pigmented spots. I often find that my face is red and inflamed when I use products with fragrances and strong chemicals. I was honestly at my witts end wearing makeup every day to cover my redness.

    Very hydrating has not caused any acne breakouts. Really like applying this straight after the shower on wet skin to lock in moisture.
  61. Super Plumping!


    Leaves my skin plump and hydrated, rarely get dry patches anymore form using this! Use it morning and night!


    Can not rave more about this!!! Have gone through my first bottle and I am just amazed. Now I am purchasing another 2 as I also have my partner hooked onto it!!

  63. Great product


    This is a great product I use it in the day and spritz before and after. My skin feels more hydrated and smooth. I will purchase again
  64. Impressed with this


    This is a great all-rounder. At 28 I still have young-ish skin though worrying a bit about ageing, and want to keep my skin fresh and hydrated. This has been a really good daily product and my skin looks healthier and skin tone more ‘even’.
  65. Great value serum!


    I wasn’t sure if the price point would deliver but it does!
    Great value serum, definitely ordering again. I used to pay $80+ and can’t see any difference.
    Very happy.
  66. Hydration Booster and great value


    I've repurchased this HA+B5 many times - always does its trick! I layer it in before my moisturiser at night and my skin looks refreshed the next day.

    There are so many other HA serums on the market, most are more than double the price of the Ordinarys! I'm impressed by the quality and value.
  67. Good as a starter HA


    Great price point for someone new to HAs. I’ve tried a few now and this is not my favourite as it’s a thicker type which sits more on the surface of your skin. I wouldn’t recommend using under makeup as it can cause peeling. Good to use with a moisturiser before bed as a hydrating treatment!
  68. Seasonal love


    I have been using this product for a while, and have noticed that in the Summer and Autumn, it made my skin feel super soft, bouncy and fresh. Now that it's winter, and I'm indoors cranking the heating, the air is really dry, I don't really feel those benefits anymore. I honestly don't think that this product is doing much for my skin at the moment. So I think this one is for Summer lovin for me! ...

  69. makes my face feel like a baby's cheeks


    makes my face feel so soft, pillowy and bouncy and I've only been using it for 5 days! immediately soothes skin, and I find works better when I've applied the ha moisturiser on top of it to lock it in before it dries, otherwise I find it causes a bit of a film on the surface of my face
  70. It's ok...


    I do like this product but I'm not a fan of the sticky feeling so I tend to only use this product in the PM and the Marine Hyaluronics in the AM as its much thinner and feels not as thick under makeup .
  71. Always Come Back!


    Every now and again I leave this out of my routine because I think it's an excessive amount of moisturiser and not really necessary, but when I do use it I remember why I love it. I can't exactly explain it. My face is more even and plump in the morning. When I do use it, i don't wake up with as many dead skin flakes around my nose that happen around winter. With the price it's a winter essential ...

  72. Love it !!


    I think this product is fantastic! It makes my skin so soft and bouncy. I use this in my morning skin care routine as I found it made my skin quite dry when using it also of an evening.
  73. Lovely serum


    I've used a few The Ordinary products and think they are brilliant - you get exactly what it says on the pack. The hyaluronic acid is really nice as a booster to other products. Personally I now use the buffet on a day to day basis but this acid is fantastic under a moisturizing mask to boost performance.
  74. Budget friendly but nothing special - Sensitive skin suitable


    You simply cannot go past The Ordinary for a budget friendly way to introduce more complex products into your skincare routine.
    Truthfully I didn't notice anything special from using this particular product. However, I also didn't notice an adverse affects, which is a little surprising given I have sensitive skin.
    For the price, give it a go.
  75. Didn’t work for me


    really got my hopes up because i heard such great things about this product! used once at night, after the first use my skin looked so much brighter however after that it went downhill and i stopped using it after a week as it broke me out. my skin had never been so bad :((
  76. I’m obsessed


    This is my first time using HA and I love! I’ve noticed results almost instantly my skin is glowing and I can’t believe the price point it’s so cheap! I have such sensitive skin and no reactions at all either.
  77. Good serum.


    Good serum. Doesn't hydrate and plump my skin quite as well as a hyaluronic sheet mask, but still quite nice and hydrating.
  78. Fantastic product and price!!


    This is such a superstar product. It really plumps my skin up. Even the deeper lines in my forehead are minimised with daily use of this serum. It doesn't irritate my sensitive skin at all. As others have said, it's not super moisturising on its own, so people with drier skin would probably benefit from using in conjunction with a light daily moisturiser over the top of this. Unbelievable price, t...

  79. HA - Oily skin girls best friend


    I did not know I even needed this until listening to the adore podcast! I have oily skin and yet after cleansing my face and moisturising it would always feel dry even though I could see dewyness. After doing more research I’ve added this in and haven’t looked back! My skin feels plump and hydrated. I have noticed my very fine lines disappearing which is great as I’m 29!
  80. Smooth Skin


    Since using I find my skin feels so much smoother and clearer. Did not experience any burning or ease-in period. Great product.
  81. Great for the price


    This does exactly what it says it will at a great price. I've used other more expensive Hyaluronic Acid serums and this one stacks up just as well. I've repurchased many times!
  82. Fantastic serum! Packs a punch!


    I recently tried this serum after seeing the number of awesome reviews - 1600+ and counting! I'll be honest - for the price I didn't expect much, but after using for only a few days, I'm a convert! With sensitive, aging skin, this serum has calmed my random break outs and has reduced the amount of clogged pores that I get. Win win. Will definitely become a staple in my beauty regime!
  83. brings moisture to my irritated skin


    A lot of my old acne products had really dried out my skin, and I have struggled with moisturisers not making my skin too oily. I've started using the cleanser, then glycolic acid, then use this serum before applying my moisturiser. It helps my moisturiser absorb and I have noticed my skin doesn't feel like it has an oily residue. Not only this, the added moisture seems to be healing my acne scars...

  84. Great HA!


    This was my first experience with HA and it's been perfect. At first the consistency was very sticky and made my face feel dry, but then I did my research and found it was best to apply when your face is slightly wet or even wet your hands slightly when applying and now im in love!
  85. Skin so soft


    The first two or so days of using this my sensitive skin was quite red after application (no tingle) but after a month my skin loves this magic juice. No more dry skin at the face creases and my foundation glides on like a dream on dewy deliciousness.
  86. Best Value HA


    Best value HA serum I have ever used, it instantly plumps up my under yes, corners of my mouth and forehead. Skins into the skin fairly well but i do find it can pill under makeup if I don't wait about 5 minutes to let it fully sink in.
  87. Hydrating & Refreshing


    I started out with Buffet but kept hearing good things about this serum too. It's lightweight, and although a little sticky after application, it dries quickly. My skin feels soft and hydrated all day.
  88. 5 Stars for Value


    I purchased this after seeing all the great reviews. I have to say it was great, not as great as expected. Skin felt moisturised but not overly. I think the price of the product got it to 5 stars.
  89. I finally love it


    I struggled with this product at first. My last HA was really watery so i struggled with the consistency of this one, and I had a lot of trouble with it pilling when I layered other things on top. But I've now figured it out! When i use it after actives, and before moisturiser I don't have any trouble with pilling. Also, I've been having MAJOR trouble with dry, peeling lips over the last few month...

  93. Simple and Successful


    This serum is a solidly good, I never reacted to it, its nice and green, and it has, I believe, helped to keep my skin balananced. It's not very acne clearing but good levels of hydration this achieves defintely helps nonetheless. A little goes a long way, it has a pleasent scent, and The Ordinary is definitely affordable. I'm repurchasing because its nice to have something between your skin and y...

  94. So hydrating


    I use this twice a day and honestly leaves my skin feeling so smooth and hydrated. It is so affordable, would recommend!
  95. use in combination


    More effective when used with straight hyaluronic serums in addition, otherwise can be too drying, best to cover after a minute or 2 with a very good moisturising cream.
  96. Another good The Ordinary product


    Great hydration, sticky solution so be careful with application. I use this under my nighttime moisturiser twice a week, alternating with the buffet.
  97. The key to hydration


    I started using this product in 2018 as I had extremely dry skin on my nose and oily skin everywhere else. The Ordinary's Hyaluronic Acid has helped so so much to help keep my skin moisturised, especially in the winter months. 2 years later, I continue to add this to my shopping cart and use it DAILY. I would recommend this to anyone who needs some hydration that lasts throughout the day. The pack...
