The Ordinary Hyaluronic Acid 2% + B5

I have very dry skin and no amount of moisturiser seems to help. But - when using this serum at night I notice my skin is moisturised and fresh the next morning, even after washing my face. I've gone through a whole bottle and will definitely re-purchase.

Love this hydrating serum. Its so light and makes my skin so smooth. I use it every morning!

I absolutely love this product. The texture is kind of slimy/sticky but I actually love it and find it weirdly satisfying, it has my favourite texture out of any skincare product that I own. It sinks in quickly and is extremely hydrating. It provides an excellent base for smoothly applying other products.

I LOVE THIS PRODUCT! I saw results within the first week - instant hydration that leaves your skin plump and glowing. I apply before my moisturiser and it just goes right into the skin. I'll repurchase once Adore Beauty updates its stock as the new range doesn't contain castor oil.

I've been using this in combination with The Ordinary's Magnesium Ascorbyl Phosphate 10% day and night, and my skin looks the best it has in years.

My skin is prone to breakouts and is highly sensitive, however I've had zero adverse affects.

I LOVE this stuff! I never realised how much of a difference it was making to my skin until I'd ran out for a fortnight and wasn't using it. Hydrating mists don't compare at all to the potency of this product on the skin. Almost immediately I can see a plumper looking face which appears hydrated and less tired. I use this straight after a hydrating toner and massage into my skin with a jade roller.

Take it from a senior beauty therapist, ALL The Ordinary products are of GREAT value and true cosmeceuticals. This product is great for anyone with dehydration, including oily breakout skin types. It does not leave a heavy feel and soaks right in, an added peace of mind for hydration

One of my faves from the Ordinary range. It took a while to get used to but I now use this before the Matrixyl and my skin loves me for it - stays so hydrated throughout the day. Definitely recommend!

The good; My skin looked more plump (hydrated) and the appearance of my forehead wrinkles looked better. The bad; the texture of the serum is hard to apply, and it can turn into a peeling foil, it also broke me out after a week of use, few under skin pimples ( for reference my skin is super sensitive, clear with occasional pimple or two during 'that time of month').

I am new to The Ordinary so I randomly chose two products with higher rating.

I do not notice any side effect on my skin after incorparating in my routine continuously for a month, I have very sensitive skin, slightly dry. Occasionally I have flakes in the mornings. Now, I do not have flakes and my skin feels really hydrated and have a very nature glow.

Definitely will purchase again if finished.

Skin feels soft and hydrated. Worn under Ordinary serum foundation and spreadable fluid primer and foundation lasted all day, better than using a usual moisturiser under a primer. No irritation on sensitive skin, would recommend

I have always had dry skin and have been addicted to this serum for the last few months. I’ve tried most of the ordinarys range and this is by far my absolute favourite I think this is my fourth bottle now. I’ve recommended and purchased to friends and family.

Very absorbing with a slight tacky feel which disappears with a moisturiser over the top. My face feels hydrated and plump with just overall freshness to it. Highly recommend

I use 5 products from The Ordinary range and every one delivers results.
It's almost unbelievable that for the price of The Ordinary that they can be so good, but maybe we have been fooled into thinking that 'beauty comes with a price' because that's not true with The Ordinary.
I use 'Hyaluronic Acid 2% + B5' in the mornings after 'Matrixyl 10%' and prior to applying 'The Buffet'. It has made my skin plumper and healthier and my foundation smooths on better than any primer I have used.

After chemotherapy my skin was very dry, I tried lots of different products before I found the Ordinary Hyaluronic Acid 2% + B5. It has made a huge difference and my skin feels softer and definitely not dry anymore and does not leave any residue.

Love this product - feels really luscious when applying - the nicest hyaluronic aide I have used! I have combo skin that is prone to acne. At the moment I am pairing this with a few other acne products from the ordinary that are super drying so the hyaluronic is not quite enough at the moment. Still a very good product.

Over the years I've invested plenty of $ on products containing Hyaluronic Acid, in the hope it will nourish my skin. But this is by far the cheapest and most concentrated and high performing product I've come across. My combination skin, needs both moisturising and mattifying... this lightweight, fast-absorbing, dream product is perfect. I apply it morning and night and often skip additional moisturising!

I found this pretty average overall. At first it seemed to have a hydrating effect on my skin but after several weeks use I really notice don’t no difference on my dryness. Feels nice on application but ultimately wouldn’t purchase again.

i just received my second bottle! I must say that this has worked well on my combination skin. I am a 40+ Asian; and at this age, I have been more committed on looking after my skin. I observed some depressions and laugh lines appearing. Over the years I have tried a lot of products, but so far, this is the only one that has made a marked difference in plumping my skin. I love the more youthful look I am now sporting! This is highly recommended!

Although it doesn’t feel hydrating when first applied, I have definitely seen an improvement in my dry, winter skin. Feeling a lot less tight and enjoying the texture. Can be used around the eyes also

This has been a game changer for me. I have tried a lot of The Ordinary products and this is a firm favourite. I have dry and dehydrated skin and have tried many moisturisers, none of them managing to quench my dry skin. Since using this my skin has definitely felt less dry and parched and looks plumper and more hydrated. It hasn't caused any breakouts, which is always a concern for me when trying new products.

This is a great hyaluronic acid! My skin always feels so nice and hydrated when using it overnight. The only downside is that if I use it under make up, my make up tends to pill and I have to wipe it all off to start again. I use this on days where I don't wear make up, or overnight to give myself a bit of a hydration boost.

I had been looking at investing in Hyaluronic acid for a while as I had heard of the benefits, but often they were extremely expensive. When I saw this product I thought that it was worth a shot - and BOY it is! I have dry/combo skin and suffer from some dermatological issues so hydrating is key. Within days my skin is looking so much clearer and more plump!

I have been using this for only a few days now and so far am loving it. I apply after cleansing at night time. It goes on slightly tacky but absorbs within a few minutes. It hasn’t made me break out at all. Before this I was using Elizabeth Arden night time repair serum and for a fraction of the price this is definitely comparable!!!

I suffer from dry skin especially in the winter, I find this keeps my skin adequately hydrated for the whole day, its a little tacky and has an egg white consistency but the tackiness disappears within minutes of application.

Great product! Makes the dry spots around my chin and nose go away within a few days. Will be repurchasing once I run out!

Makes my skin more supple and less dry skin.

I love this stuff, Sooo hydrating and plumped up my mature, sensitive skin so well with continued use. Have become a big fan of The Ordinary range in general, very reasonable prices and very effective. This product is no exception.

I’m on my third bottle and this is magic in a bottle. My skin has been so dry and crusty all winter and this has helped keep my skin hydrated since I first started using it. Love!

I absolutely love this serum - I live in a rural town, with very hard/chemical water, which is constantly leaving my skin feeling really dry and dull. I use this now every morning and night, along with the Buffet serum too, and my skin now feels so much more replenished and WAY more bright/even. Definitely recommend this product!

This is the product everyone must try. It’s so hydrating and I noticed an instant hydration boost. I can’t rate this product highly enough or recommend it to enough people! Although tacky after applying once moisturiser is on that disappears and just leaves the most beautiful plumped and hydrated skin

This is a lovely, simple yet effective HA serum. I have tried other brands in the past and thought HA was not for me as the products always irritated my skin. Must’ve been the other ingredients because this HA leaves my skin soft, supple and hydrated. I love the Ordinary products and have been recommending to all of my friends.

I bought this to make my own sheet masks. The slippery texture and HA and B5 content make it very suitable as a booster moisturizing treatment. I combine it with the Niacinamide serum from TO, and/or borage seed or Squalane oil from the same brand and have a custom made mask!

Great product! It's my third bottle. It's a little bit sticky at first, but after applying moisturiser on a top of it, it feels fine. In the mornings I wear it after Buffet. After first two weeks of using these two products, my colleague at work noticed that my skin improved in texture and asked me what I changed in my skin routine.

I mix this with the vit c powder from the ordinary. Leaves my skin hydrated and soft! Beautiful and affordable!

Best vit c I've ever used! Super fast delivery and great customer service. I have already recommended it to my friends!

I can feel a difference even after two applications, especially when applied with the The Ordinary Natural Moisturizing Factors + HA 100ml, skin looks and feels fresher! Definitely making this a staple in my beauty regime.

I love this product, and can't live without it. I feel that it smooths my skin, banishes dead or dry skin, and just generally acts as a fab base for all my other products. This is a staple in my skincare routine, even if I start mixing other products up.

Incredibly hydrating! It’s a little tacky when you first apply it but that goes away after a couple of minutes. When I first got this product, my skin was slightly dry and my lips were chapped. I applied this morning and night and you could feel the improvement straight away, after 2-3 days of use any signs of dry skin we’re completely gone and my lips felt plumper and smoother than they had in a long time!

I've seen a major difference in skin texture after using this product, my skin looks so healthy.

I’m not sure if this one really doesn’t that much to my skin. My moisturiser has hyaluronic acid in it so i can’t see a lot of any results of using this product.

Just recently I have discovered The Ordinary products and I jus love them. I use it every evening after The Ordinary toner and in a month already my skin has so much improved, it feels clean and moistened. Will be using this in the future for sure.

Easy to apply, a little tacky but gone once you apply moisturiser over the top
i would always put a bit on my lips when they were super dry and it gave instant relief and results!

I used to get dry patches on my skin, usually on my cheeks, every winter to the extent that I was using a Clarins night cream (quite expensive) during the day to try to stop it and while it helped it didn't stop them completely, but since using this serum under my (The Ordinary) moisturiser I have not had any more dry patches. Just goes to show you don't have to pay a lot of money to get a quality product.

This product is part of my skincare regime but there is one thing I don’t love about it... sometimes it can leave a bit of a ‘film’ on your skin. Therefore I tend to only use it at night. I definitely feel it help with my skin hydration and my dehydration lines on my forehead though, hence why I keep using it! I also put a generous application of this on my lips at night too(and keep my mouth closed when it dries/absorbs! Haha) it’s my little miracle to combat lip wrinkles :)
Personally wouldn’t recommend it before makeup application, but as a night-time hydration booster definitely :)

This is another beautiful serum from The Ordinary I can't live without. It is the first serum I apply after cleansing and hydrates my skin so well and gives you a beautiful healthy glow. Can't recommend it enough! Love!

Have been using this in combination with The Ordinary Buffet. AMAZING!

I have dehydrated skin, as I approac 40, but still suffer from acne and redness, along with the fine lines creeping in and just looking tired and dried out.

I've only been using this a week, but the way my skin goes, know this is a winner. No spots at all, my skin looks fresh and happy, so much so a friend commented how good it looked last night, despite the fact I'm averaging about 4 hours sleep a night at the moment.

At this price point, this is definitely a HG item for me now and will continue to use.

I use this product around once a week just for extra hydration, it works well but it can be sticky when putting it on and doesn't have very good coverage because of this.

I have particularly dry and flakey skin, so I have combined using this hyaluronic acid with retinol. I use it in mornings and evenings before applying cream and it has made a huge difference in getting rid of dryness! I especially love that its 2% as opposed to other brands which have a higher percentage and tend to be too harsh on skin

I find this one a bit sticky when layered with other products and because I already have a number of serums in my routine, this one dropped out of the mix for me. It does the job as a hydrator and I think if you have a very simple routine, there is no harm in adding this to your mix (especially for the price!). The Ordinary Marine Hyaluronics is much lighter and doesn't leave a sticky residue so I prefer that one when I need a hydration boost.

Does it hold in moisture? I think so - certainly my skin wasn't dry whilst using it. But...
there are several products from The Ordinary that also include 2% Hyaluronic Acid within them (I'm currently using the Alpha Arbutin + HA) so, save a few dollars and eliminate another step by using a combination product.
If you *only* want HA, then this is a good product - no complaints at all.

Not the most hydrating thing I own, but definitely helps in layering hydrating products in winter. Can be a little sticky.

Too harsh for daily use on my skin which is fair and broke to pigmentation and breakouts. Using 2 -3 times a week is perfect though and my skin is so much more hydrated and evenly toned

I was skeptical buying and using this. Used it a few times and I love it. I put it on after my toner and before my moisturizer and it leaves my skin feeling hydrated and plump. I have combination skin but it balances it out perfectly. I also have redness from being sensitive and it doesn't make me flare up either. A great addition to any beauty regine

I saw quite drastic improvements in my skin after using this for a month and half it was fantastic it made my normally quite dry skin a lot smoother and didn't break me out or anything so i'd definitely recommend this.

This stuff is great. At this price point you will not find better. Sure you can get more full on hyalronic acids but for a good every dayer application you'd be hard pressed to find better. I will continue to buy this and use it daily

Combo skin- tends to get oily in the t zone quite easily.

Bought this to give my skin some extra moisture over the winter and was not disappointed. The product added real moisture to my skin without making it oily or breaking me out.

Side note- It acts as the BEST primer as it has a tacky finish for a few minutes after applying

I have oily/combination skin and bought this products to help with hydration. Unfortunately I can’t wear it under makeup as it can start to peel under my moisturisers/foundations. The initial finish is sticky which I don’t mind because it eventually smoothed out when you pat it into the skin, however I haven’t noticed any long term results and I have used almost a whole bottle. While this is a very affordable product I think it is worth spending a little more on something better.

I have dry skin from chemical exfoliators (adult acne over here). I didn't see a difference using this product. The best I found was if I put some jojoba oil on after cleansing, followed by the HA, followed by a thick, night moisturiser but honestly I think oil and a moisturiser is enough without. I also don't like the soapy consistency of this serum and I find the dropper dispenses too much product in one go. I do think it is good value compared to other HA products.

I have combination skin and I use this with the plant-derived squalane, and it is such a great hydrator without making me oiler or break out!

Its an okay product nothing extraordinary, the problem is that its not very hydrating even though I have combination to oily skin I have to layer a good moisturizer on top and you need to apply it to a damp face otherwise it absorbs really fast and become sticky and you wont even get the chance to spread it all over the face. This has also caused some breakouts so yeah I dont think i will get this again.

This is a nice serum that soaks into skin well, however I didn't notice any big changes in my skin after using regularly.

I love this. I makes the moisture in the facial products I use soak better. It grabs the moisture so I love mixing with wrinkle, eye and lip moisture treatments esp nighttime ones.

Clear with no smell and a slight gel consistency. Seems to protect against cold weather wind chapping

I have only been using this product for a week and it has made a huge difference to my skin. I put this on as soon as I get out of the shower and I can feel it really soak into my skin particularly after a hot shower. Although it’s a little sticky when first applied my skin feels so soft and hydrated when it dries. I have been getting a number of complements on the finish of my makeup and although I am using the exact same products as before I believe it’s all thanks to this little magic bottle giving me such a smooth base.

Not sure about this one. Definitely can't wear it under make up as it can become gritty and my make up doesn't go on properly. Went through whole bottle and not sure if there was much change to my skin overall, but I did notice a like plumping of my skin the morning after use.

Really good product, it does seem to work well. It's so cheap so just give it a go. Would recommend

This product is pretty run of the mill. It’s effects seem really hydrating upon first application but you quickly realize after a few days that a lot of product is needed for what is only a minimal difference. Unlikely to purchase again.

Have finished a bottle with no noticeable differences to my skin quality. I found it quite tacky unless you give it a lot of drying time and there was a lot of pilling when I used products on top of it (tried water and oil based products without success).

Really easy to use and soaks in beautifully. I love this product and use it daily.

This is good but I don't really feel like it does much for me

This is my favourite Ordinary serum and I have repurchased several times. I have combination skin which often ends up with dry patches in the winter.
I think a combination of acids in the evening with a decent moisturiser and this serum in the morning have really helped keep the dry patches at bay.
I use this serum after spraying my face with a mist which really helps the product go far, it has a nice sweet smell and it feels nice going onto my skin. It feels really light and breathable which is great for those hot days when you don't feel like slathering heaps of product onto your face.
As with all Ordinary serums, a little goes a long way and it will last you for ages.
I think this is a must for anyone looking at getting a bit of extra moisture into their skin.

This is good but I didn't really feel like it did anything to be honest

This is such a staple for my dehydrated skin. My skin can get dehydrated, especially in winter, and this little jar of magic helps plump up my tired skin and reverse the cold air's damage.

My skin feels more hydrated and plump after using this. I have combination skin and I use this before moisturiser. I can skin my skin looks more hydrated after constant use

The greatest way to get your Hyaluronic in a flash at an incredible price. I saw rapid improvements in my skin texture after using this daily. It's 100% a skincare staple of mine.

I'm in my mid 20s and have always suffered from acnes since I was 13. I've tried a lot of products overtime since my main problem lately is being extremely oily which causes acne and I was going to order niacinamide since it's more suitable for my condition but I accidentally ordered this which is known for its hydration. I've only been using this day and night for the last 2 weeks but my skin has become A LOT less oily and I dont know why but it just did. The niacinamide came in after a few days and for some reason this hyaluronic does a better job for me.

I’m in love of this, I think once you try you can’t let it go. I have oily skin with breakouts and this product is súper hydrated for your skin. It’s absorbed in seconds so you skin is Matte after using it. I use this product in the morning after cleaning my face in conjunction with the buffet from the ordinary. Love the combination!

I have quite dry, sensitive skin and only use this product at night time, and have been using it for about 4 weeks and my skin has never felt so soft!!Will definately be a regular purchase from me!

so hydrating and makes your skin look so dewy

I love this serum. It is a little sticky when applying but once it settles it is so hydrating my skin looks dewy. I use this on top of the buffet serum and love the combination.

generally speaking, this is a very easily absorbed essence. I have a very oily skin and i find this friendly. I use this product before my serum day and night. since Hyaluronic acid is so lightweight, you will at least use a cream after it.

I love how hydrating this product is for my skin - instant difference. My only small criticism is that I find it quite sticky, but if you let it sit on the skin for a few minutes before adding anything else it does soak in and the stickiness disappears. It's been well worth putting into my skincare routine at night and has really helped my dry skin to be hydrated without making it oily.

I use this in my skincare routine, I don't see a significant difference but my face is hydrated from all the products I use and I think this definitely does help! I would recommend it,

Absolutely love this product! My skin has felt so much softer and so much less dry :) the perfect product to get me through a cold melbourne winter!

One of the best serums i have ever used and a great price. I have been using it at night and morning for over 3 weeks and my skin hasn't felt this good for a long time. Definitely will be using it :))

I react to most skin treatment products but this was not an issue at all. My skin is looking plumper and brighter after just 2 weeks. Super quick absorption and lightweight texture.

I didn't realise how well this product worked until I ran out of my first bottle and stopped using it for a while. My skin went back to looking dull and dry. Once I finally bought it again, my skin was so much more plump and dewy. I have sensitive acne prone skin, but this does not irritate or brake me out and I will be re-purchasing for a long time. Definitely recommend it to everyone.

I’ve been using this product for 3 months now. I have very very dry skin and I haven’t started aging yet but it’s never too young to start taking proper care of your skin. I apply this day and night and it provides a nice hydrated base before I put on my moisturiser and it almost has properties that allow my makeup to stay on longer without the use of a primer, I think it’s more of a right now solution as opposed to a long term solution as I still have dry skin but this defintly helps manage it!

This serum is SO LIGHT. It works really well on my combination/oily skin without causing irritation or clogging pores. It leaves the skin feeling smooth and moisturized. I love using this before bed and I wake up with fresh hydrated skin. Love this stuff.

I can feel a really big improvement in my skin since using this, I can definitely see that my skin looks plumper and less texturised, I think this product is great for what you get considering the price and I like this product added with my moisturiser as an intense nighttime hydration.

I’ve been using this product for about two weeks now and I am happy with the results, you don’t need much to cover your entire face and afterwards, you may experience a tightness feeling on your face but it also leaves your face looking so smooth. I always use a moisturiser afterwards because for me, it does make my skin feel quite tight and dry but overall, I am happy with the results I’ve been experiencing since using this product. I have oily/combination skin and this product seems to work well for me!

This product is great for the price point. I have been using it for about 4 months and have noticed a difference in the smoothness of my skin and the overall hydration. I have tried other brands that are more expensive, and i would say that this is a good alternative if you are price conscious, however, it seemed as though you really do get what you pay for. This is a lovely product, but i will be switching back to my old favourite, despite to price hike.

I have dehydrated combination skin and i needed an alternative for the medik8 hyrdra b5 as it was too expensive to keep repurchasing.
This little gem is the best, Leaves skin feeling firm and supple, a little goes a long way! Using this for 3 months now and the hydrating effects are awesome!

This is my new staple! I have combination skin starting to show signs of age and this immediately improves the look of my fine lines. Soaks in quickly and my skin feels so lovely after using. Cannot recommend this enough! Should be a must in any The Ordinary regime.

I mix the hyaluronic acid with aloe vera gel to use on my skin as I have very sensitive skin. It works very well to soften and moisturize my skin without any oilyness or irritation. Very happy with this product and will definitely continue to use it.

I did some extensive research on using Hyaluronic Acid and it sounds like a magic product. And it is. After using for a month i can tell my skin has more natural moisture. And i find the Ordinary brand the perfect price point.

I was a bit skeptical about this but it has exceeded my expectations. I have dry sensitive skin and hasn’t given me any rash and gives my skin a nice plump appearance. My skin feels more hydrated and has been a great addition to my skincare routine. I use this then the peptide serum then a moisturiser. I feel it makes my moisturiser sink in more. For the price it’s extremely good value for money. Great it has no fragrance so genuinely think anyone could use this and benefit from it.

it was recomended to me by a friend and since I have added it into my skin routine, day and night my skin has definitely improved, keeping my skin from being oily, while not over drying it. Also this brand is so affordable and I would definitely recommend it.

Unfortunately, this product broke me out. I have sensitive, combination, acne-prone and dehydrated skin, and was hoping this would be great for both hydration and blemishes. Unfortunately this broke me out all over my face - including areas that don't usually break out. Might work for some but did not work for me :(

I use this to Hydrate & plump it made my skin feel softer quite quickly. It is a simple product that works well.

Can't complain have tried the Hylamide one which is more hydrating but for me is less plumping.

I have combination skin that gets oily in the t-zone but pretty dry around my cheeks and chin area. I was looking for a product that made my skin feel moisturised and hydrated but without the oily greasy look. This does just that!! My skin feels amazing with it and makeup goes on amazingly. Definitely recommend!!
