Helps My Acne Skin Survive The Winter Cold



Definitely saves my skin in winter but isn't necessary for me during summer.
It definitely does what it was designed to do:
- Hydration boost and easy absorption.
- Plumps and nourish the skin.

I use this in the morning before moisturiser as a hydration boost as well as before night cream every night.

I have adult acne and this helps my pimples be less flakey and dry. According to research acne occurs because of lack of hydration to the skin. Use this along with neutrogena hydro boost or another hydrating moisturiser and you'll notice a difference in your skin.

The packaging is amazing, love reusable glass bottles and its such great value for money. Give this a go if you have very very very dry skin, if not just get a super hydrating moisturiser instead.

Didn’t do anything for me


I brought this to see if it lived up to my cosmeceuticals skin care....well...it definitely didn’t. I did not like this product at all. The texture is sticky and the smell is very unpleasant.
  1. Plump


    Great quality considering the price. Adds moisture and makes your skin super plump
  2. Not for me


    I've use HA before from another brand and thought I would try The Ordinary due to its price point. It initially tingled on my skin and cause some redness. I do have very sensitive skin though.
  3. Hydrating


    I used to not like this product as it feels sticky, however someone told me to use a facial spray underneath and now i really like it as it spreads over my face much better and feels more hydrating.
  4. Staple must have


    I think this is the best HA for the price. Does what it says it will, absorbs and layers fine. Can go under foundation, smells ok. I’ve always got one or two bottles of it.

  6. hydration- even for acne prone skin


    After being given a small sample of hyaluronic acid I was on the lookout for an affordable option. I gave this one a go and have been so impressed with the results. I have had acne-prone, sensitive skin for the last 10 years and have been so scared about overdoing product on my skin. This product is easily absorbed has cleared up my dry patches and has become a vital step of my skincare routine.
  7. Amazing prodruct


    This product is amazing, leaves my skin really glowy and hydrated, but no oily, that's what I love about this product, I mix it with my moisturiser and apply it to my body as well.
  8. Well priced and last long


    a little goes a long way! this particular serum is only needed to be applied as a thin layer, it meets my expectation and i love this brand that always sell its product on affordable price tag.
  9. Best value product!


    This is such a great serum, it smooths over my skin so easily and keeps it moisturised and gives it a healthy glow for such a low price!! Can’t beat it
  10. Great for newbies

    Christine W

    This worked really well for my dry skin. I think its a great product to start if new to cosmeceutical skin care and super wallet friendly. I've been using this for a few months and now wondering if it's time to move onto something else as I'm not feeling the benefits that I initially did when I first started using it.
  11. amazing results!


    I have super sensitive as well as dry skin, so I tried this product out in hopes that it'll leave my face more hydrated and supple. It certainly did its job! I'm onto my second 100mL bottle now
  12. life saver


    has completely changed my skin. my skin is now so smooth and has gotten rid of the horrible texture of my skin
  13. Wouldn't Recommend


    I really wouldn't recommend this product no matter how much or how little i use it always peels off my face which is a real problem when using it before applying make up. I've used it on its own and mixed with other skin products and makes no difference even when applying it and waiting a while before putting anything else on. I also find it has a really sticky feeling on your skin after. I haven'...

  14. As good as the pricey ones


    Works well as a hydrating serum underneath other products. I’ve tried many more expensive hyaluronic acid serums and I think this one is just as good. This isn’t the case for all of the ordinary but I rate this product. Why pay more when you don’t have to?
  15. Perfect hydrator


    I love how this product hydrates my skin without feeling like a thick layer of cream. I used this during my holiday and it was all I used to keep my skin soft and happy
  16. Wish I bought bigger!


    Lovely product - feel it truly plumps and moisturizes the skin. Skin looks healthy, where previously dry or tired.
    Only wish I bought the supersize bottle (my next purchase!)
  17. Highly recommend


    I have started using the ordinary hyaluronic acid for 3 weeks. It works for me and the price makes me fall in love with it. I just received my 60 ml bottle my second purchase.
  18. plumps skin


    A good addition to the my ordinary skin care routine. I use this at night and find that it plumps skin and doesn't irritate my reactive skin. Use in conjunction with other the ordinary products my skin is looking great.
  19. B5 + HA


    I found this product gave my face that hydration and glow it was missing. The texture and feel of my face has become so smooth
  20. Affordable range


    This product is so affordable and great for hydration and perfectly layer well before heavy serums and oils.
  21. Well priced and good quality

    Jadey B

    I was looking for a new AM and PM facial regime as I realised my skin was looking dull and flat. So I got some tips from Brooklyn on here and all of his recommendations have been amazing. I found this product gave my face that hydration and glow it was missing. The texture and feel of my face has become so smooth and has that healthy glow about. I’m combination skin and this is perfect to even me ...

  22. Average


    For a hyaluronic acid serum, it's great value. I don't find it nearly as hydrating as my other serums (I have very dry skin) and I don't like the sticky feeling I'm left with - definitely like to seal it with a moisturiser afterwards. I was getting lots of little bumps on my forehead and I have a feeling it was this product!
  23. Great for dehydrated skin


    I generally have dry skin and I use this serum to boost hydration in my morning and evening routine.
  24. Smooth fresh skin


    I love using this as a hydration boost every night and I love how my skin feels in the morning. I tend to have oily skin which can be prone to breakouts and this has not caused me any problems. Its moisturising and nourishing under the surface :)
  25. Like a glass of water!


    I've bought 3 bottles of the 30ml bottle already and absolutely love it. I find it is very hydrating (especially when you apply it to a damp face) and it helps prevent any dry patches.
  26. Living for this


    I kept hearing about this (and in the podcast) and decided to try mixing it with vitamin c before my moisturiser every morning. Well it’s amazing and my skin is so dewy and radiant. Honestly I didn’t realise how good my skin could be and I have to say it primes my face better for makeup which looks natural and glowy on top. Big old recommend from me!
  27. Leaves a weird film on my skin


    I really enjoy this product but only if i mix it with some rosehip oil. If i put it on my skin by itself it doesn't absorb properly and leaves a weird film on my skin that crumbles off when i try to apply make-up on top. I think this is a problem only i have though as i haven't seen anyone else mention it in reviews. I have normal-oily skin and even though it's a hydrating serum i find it doesn't...

  28. Dried my skin out


    I fell in love with Hyaluronic Acid after using the Esmi skin treat but unfortunately cant afford to buy it regularly. Thought id give this a go but it actually dries my skin out. I now have flaky/red and peeling skin on my inner eyebrows which is always where i seem to react when products dont agree with me. Such a shame, i wouldve loved to have saved a few dollars!!
  29. Sticky and pilly


    It's a great product if you are using it alone under a moisturiser, other than that it does seem to pill when combined with other products or if your rub it in too much. The product itself is super thick and leaves a sticky residue that feels warm if not paired with a water based moisturiser.

    I have found the best way to use this is to pat some water on your face or mix in with the p...

  30. Gorgeous texture and super hydration


    Love this product, it is feather light on the skin yet is hydrating and non irratating. I notice under my eyes where I have light lines, when I put this on with a simple moisturiser they almost vanish which is remarkable. My skin feels healthy and my persistent dry itchy patches have not reappeared after using this consistantly.
  31. Great value B!


    I've found The Ordinary's Vit B to be fantastic. I've used expensive versions and I have found no difference apart from the way it feels. In my opinion great value for a good product.
  32. Super Hydrating


    I love this serum! It’s very gentle on your skin and is incredibly hydrating. My skin feels so soft and plump after I use it. I use it morning and night under moisturiser. I used to have patch’s of dry skin around my nose and now they have completely gone. It’s now a staple in my skincare routine!
  33. Go to serum


    Bought this as recommended by my facialist. Really improved my dry dull skin. I use alongside the niacinamide and moisturiser. Have repurchased multiple times!
  34. Moisturiser base


    Didn't think this was doing much until it ran out and I realised how necessary it is under my moisturiser.
  35. Good addition


    Good addition to any skincare regime. I use this morning and night and provides the right amount of hydration for me. I have combination skin and this works really well for me.
  36. Great for glow


    I love this product it is so much affordable compared to other products I have bought and it is great that it is a light serum which can be used with other products instead of a heavy cream. Leaves skin smooth, plump and glowy
  37. Great product - buy the supersize bottle!


    After battling eczema, dry and sensitive skin during my pregnancy and post pregnancy, I had tried so many different products with none helping my dry, flakey, itchy and sensitive skin. The Hyaluronic Acid , along with a number of other products in The Ordinary hydrating regime, has been amazing with my skin completely clearing within two weeks of using the products. Definitely need to follow this ...

  38. The best


    Works well on my oily skin ! One of my favourite ordinary products
  39. Great


    I use this every night and my skin does not have dry patches anymore. It is so inexpensive
  40. Hydrating


    I like this, and it works well for its price! I use it when my skin is still damp after washing my face in the morning, and follow it after a few seconds with my moisturizer to lock everything in. I haven't tried other HA products so I am not sure how it compares but its definitely worth a try if you have dry skin.
  41. Best serum I have used


    This serum is now my daily go to. I have had massive improvements in the skins texture, dryness and as a freckly person it has also made my whole face more even and just gives my skin a great glow.
  42. Good quality HA


    I have dry skin and this product just sinks in, plumped my face, easy to incorporate into my routines. Such good value for money and a staple in my skincare routine now.
  43. Provides great moisture


    Having oily skin means that i find it hard to find a moisturizer that isn't to heavy and greasy. However this products is great as it does't feel greasy and slinks right into my skin. It is very moisturizing, however, if you have drier skin you might need to follow up with another moisturizer.
  44. Great on sensitive rosacea skin


    I have hypersensitive skin with rosacea, which I developed a few years ago. This serum, as well as a few other products from the ordinary have completely changed my skin for the better. Amazing stuff, and sooo cheap compared to the other expensive brands I was buying that claimed to do the same thing!
  45. Great serum!!


    Seriously this is so good. I use it every day and after dermapen. It's so affordable!! I add some to my moisturiser when my skin is extra dry to give it a boost.
    I've used other hyaluronic serum from other brands and it would cost me $100+. This one feels exactly the same. Definitely a permanent collection in my skincare routine.
  46. Good if you are just starting out


    I must admit I really liked this product when I first bought it. My skin felt plumper and more hydrated. However, I have since tried other brands of H.A. which are far superior products. The ordinary HA tends to leave a residue on the skin. I would recommend this product to those just starting out in their cosmeceutical journey and don’t want to spend big straight up. I will finish the bottle but ...

  47. My holy grail!


    I absolutely love this product, it makes my skin feel and look so good, it's definitely my favourite product and my main must have. It makes my skin moist, plump and glowing. I also use it on my hands and even my hair! I'll definitely be buying the bigger size from now on. <3
  48. Brilliant


    This is a brilliant and cost effective product. It is kind and gentle to the skin, yet was able to get rid of blemishes within the first week. It plumps out fine lines and helps with dry skin. It left my skin feeling smooth and vibrant. Highly recommended.
  49. Great product


    This product is part of my everyday facial routine. I use it day and night immediately after cleansing. The trick is to apply whilst the face is still slightly damp from cleansing. This allows the product to work at its best to draw moisture into the skin for that plumping effect.
  50. amazing


    I suffer from dry skin and this product keeps my skin very hydrated! I would recommend this to anyone!
  51. Great Start

    Kirsten M

    This Hyaluronic Serum is a great introduction to both The Ordinary and Hydrating Serums.
    It isn't the best Hyaluronic Serum but it does the job.
    Took a while for me to notice the added hydration and definitely works best when applied straight after cleansing when your skin is still damp.
    The price point makes it worth it's wait in gold!
  52. Hydrating


    Aims to hydrate the skin to create a smooth and plump appearance. Love this.
  53. deep hydration and lightweight


    It really works, deeply hydrate my skin but not irritates it. It is very lightweight and absorb into skin very quickly. But I don't like its smell.
  54. Didn’t do anything for me


    I brought this to see if it lived up to my cosmeceuticals skin care....well...it definitely didn’t. I did not like this product at all. The texture is sticky and the smell is very unpleasant.
  55. Good start to hydration


    I got this after repeated recommendation from friends and also listening to the adore beauty podcast. I have dehydrated and sensitive skin/rosacea and I was reading articles about dehydration possibly causing the redness. Had previously also tried a panthenol cream before which worked well to soothe my skin so this product seemed the perfect way to combine both in an affordable way. I applied this...

  56. Great entry level product


    This is my first Experience using a product of this type but I’m in my late 20’s and figure I need to start taking it up a level. I’ve been using it for a week in my daily skin routine before moisturising and my skin feels great! My pores look smaller and my skin is really soft.
  57. Your new skincare saviour


    No joke, this is my new everyday must! I saw my skin responding to this product after the first use. I use it every night to hydrate my skin and I have noticed a reduction in fine lines and I’ve had people comment on how much more awake I look! Can 100% recommend.
  58. Great price


    No nasty ingredients and amazing price, but I don’t know that I’ve seen much of a difference since using this. At that price I guess it’s worth trying though!
  59. Good for price


    I haven't really noticed much of a difference with this, however it is so cheap that its worth a try anyway. It does feel slightly sticky so only a little is needed.
  60. HG


    Years of eczema and dry skin have left my face looking dull. Started using this 2 years ago and it's now my HG. Will continue to order it from AdoreBeauty as they have the cheapest The Ordinary products that ship to NZ (for free too).
  61. Love for every season, especially for flights


    This is such a great serum; if I am feeling super dry and flying a lot and use it morning and night, mid-flight and every opportunity in between. It is a really great price point too for this kind of use! Other times I just use it morning or night as a constant serum on rotation and it always works well with everything else.
  62. Hydrating and nourishing


    I purchased this product to hydrate my dry skin and smooth my complexion. Within the first use I noticed a difference in my skin, 1 week later and my skin is no longer flakey.
    The box recommends twice per day however I only use this nightly and it has worked.
  63. DEFINITELY lives up to the hype


    THIS PRODUCT IS MY NEW BEST FRIEND! Oh my god when I first looked into this product and read all the reviews I thought it was too good to be true, until I tried it for myself. I use this product at night time after using the Ordinary Squalane Cleanser, then apply the HA, followed by the Ordinary Hyrdating Moisturiser. When I wake up in the morning all of my slight imperfections have disappeared an...

  64. Keeps my skin moist


    This stuff is fantastic - it's not so much that I notice it when I use it, but I notice it when I don't. My skin is drier and is more dull. The texture is quite tacky but it absorbs quickly, so it doesn't stay sticky.
  65. Great when paired with additional moisturiser


    I find I need to pair this with a moisturiser, as it’s not as hydrating as expected. This is really convenient to travel with if you don’t want to bring lots of products
  66. I don't think I use this product correctly?


    Everyone loves this product but for me it dries very weird on my skin! When I initially apply it feels like a massive surge of moisture, which is great! But as soon as it dries it feels like dried egg whites. It also peels and balls up as soon as I add any other product.
  67. Love it


    Definitely one of the best things I have added in my skin care routine as of late! I have oily skin that always felt dehydrated and this has worked wonders for me. Leaves me with a nice glow and doesn't feel heavy or like it is clogging my pores. So affordable too!
  68. Moderately hydrating but useful


    Not as hydrating as other Hyaluronic products I have tried but very useful to mix with other products from The Ordinary. When my skin is sensitive it works perfectly to mix with The Ordinary Retinol products or Niacinamide.
  69. Really good intro to hyaluronic acid


    I've never used hyaluronic acid before. I have a pretty good skincare routine (AHA, BHA, Vit C, Retinol - the works), but I was looking for an additional moiturising product to make my skin more plump. Before investing in a more high-end product I wanted to give this a go to see how my skin responded. I love it. I've had friends comment on how my skin looks more plump and refreshed and I owe i...

  70. You get what you pay for


    This was the first Hyaluronic acid I ever tried, so originally I thought it was pretty good. However, upon trying a more expensive, cosmeceutical brand, I realised this product doesn't do much in the way of plumping your skin or making it glow... it is also very sticky and feels a bit uncomfortable. I would recommend this for teenagers.
  71. Great value


    This can be a bit sticky but is otherwise a great serum for the price - it definitely makes a difference when my skin is feeling dehydrated!
  72. Game Changer!


    I recently added this to my regimen and it has been a complete game changer! I put is on straight away after cleaning while my face is still slightly damp, allow it to full absorb and then put my active ingredients over top. It has made my other skincare products work so much more effectively and has totally brightened my dull skin. Cannot live without this now!
  73. Great for extra moisture!


    This is one product that I can’t get enough of. I have dry skin mostly (oily around the nose) and I’ve noticed a significant difference in the softness of my face since starting this product.


  74. Good, but can't see obvious results.


    I've got combination skin, but it gets quite dry in winter. This product is a great alternative to use if you need a quick pick me up, however it does have a almost sticky texture after application which takes a while to absorb. My skin isn't particularly sensitive however it does sting after cleansing and makes it a bit red on application. For the price it is good value and works well. I would re...

    This has an initial "tackiness" when applying that I didn't like at first, but it quickly absorbs leaving my skin very smooth. It's hard not to keep touching my face! I've been using this morning and evening and have been enjoying the textural shift I feel. It leaves a dewy finish but does not clog my pores or leave me feeling paranoid about breakouts which a lot of other moisturising products do!...

    Have tried other Hyaluronic acid products and they are more expensive yet this product does a better job. It’s so smooth after applying and the skin absorbs it in seconds, would highly recommend giving it a try.
  77. Best hydration ever


    It is my third time buying this product. As someone with extremely oily skin, I tend to stay away from anything oily/greasy.

I would definitely recommend this product to others, especially those with oily ...

  80. Shrinks pores and hydration magic!


    Highly recommend! Cheap, but high quality. I use it a small drop in mornings and evenings and as soon as I put it on my face plumps up and pores look so much smaller. Love it.
  81. Hyaluronic


    I have combination skin, which used to be oily and has been dryer after use of roaccutane for acne in the past. This has been a lifesaver, as I often don't like heavy traditional moisturisers, and using this at night has been a great way to keep my skin hydrated, especially after microdermabrasion. Much better value than other hyaluronic products on the market.
  82. Great for dry skin


    I get a lot of dryness around my nose due to allergies. This has reduced the dryness significantly. I apply morning and evening. Will pick up the larger bottle next time.
  83. Apply straight after cleansing


    This product is a great go between just before applying moisturiser(you don't have to use as much) and still feel hydrated
  84. Not bad

    Kate Y

    I have combination skin and it made my face quite sticky. I tried to put less on and pat in the skin but didn't notice a difference. I like the idea of a wallet friendly serum but I have felt more of a difference from other serums that may cost a little more. Worth a try though!
  85. Keeps my skin hydrated


    I have normal to oily combination skin. I don’t usually have problems with hydration but after skin needling or microdermabrasion, this is my go to product. Very gentle and super hydrating. Keeps the skin looking plump.
  86. Staple


    Can’t go past it, great for locking in serums. I sometimes mix a bit into the natural moisturising factors.
  87. Love it!


    I work alongside a Plastic Surgeon who is convinced that the only product that helps skin is Hyaluronic Acid. It is great to find a high quality but affordable alternative to what I have been buying! Lovely packaging, lovely product... I am very happy and will take the advice of my colleague as he knows a lot about avoiding the signs of raging!
  88. One of my favourites!


    Love this brand and this particular product from them. I am a flight attendant and my skin gets dehydrated from all the flying. I love using this daily to give my skin a good dose of moisture. It is nice and easy to spread on my face and dries within seconds. Price is brilliant! Vegan and cruelty free. Natural product. Highly recommend!
  89. Love!


    Great serum, has replaced my hydraluron serum. Great price point as are all ordinary products
  90. Great value!


    Like most products from The Ordinary, this is great value! Very hydrating, though I also layer with a moisturiser as my skin is very dry. You only need a little, or it will start pilling!
  91. Hydrates!


    This serum really hydrates my skin, I put it on morning before my make up and at night time after cleansing and toning. It really does hydrate the skin, feeling fresh and dewy. However, I don't think it does much more than that, I have been using it for months now because the price tag is good just for hydration.
  92. value for money


    I keep returning to the ordinary HA. It Is not necessarily the best one I have tried, but it is the most effective one I have used that is under $30. I find application & results much better if patted onto damp skin.
  93. Great value for money, hydrating


    Once you get the hang of applying without pilling, it is a great value for money hydrator. Skins feels plump and hydrated. For my skin type I do layer with a moisturiser to lock the hydrating in. I also find applying on damp skin helps to seamlessly sink into the skin.
  94. Good hydrator


    Have been using for a few months and at first I didn't notice any difference, but if I don't use it for a few days my skin feel quite dry and dull. I think its a good step to add into my morning skincare routine
  95. So good!


    I've never used a hyaluronic acid before so I was a bit sceptical about the purported moisturising properties but it definitely delivers. A tiny drop goes a long way, too.
  96. Great product, reasonably priced


    Love this product. I use night and day & find it really helps my skin. The price is fantastic & I think it is great compared to more expensive options.
  97. Great hydrating alternative


    I have been a user of Skinceuticals Hydration B5 each morning after cleansing and prior to moisturiser/SPF to target dehydrated skin (35yo female). I have been using The Ordinary for now 2 weeks, and cannot tell the difference. Great value for a great product.
  98. Love it


    This product is so cheap and it really works. I use it after I cleanse and it does feel tacky for a while but after a couple of minutes I apply my moisturiser and I'm good to go to bed or apply make up. It is very gentle and does not irritate my skin at all.
  99. Cheap and effective!


    This is a lovely hydrating serum that is amazing for the price! It wont do much beyond hydration and calming but it doesn't claim to!
