Light & hydrating
Love that this is so lightweight and not at all sticky like the ordinary HA.THE BEST!
This is their best hyaluronic acid. I add a few drops into my palms, clap my hands and pat everywhere on my face, neck and chest. It absorbs instantly, plumps and gives me glass skin. Have gone through 10+ bottles of this over the years and I’ll never use anything else!Better than their other serum
This Marine Hyaluronics serum is much better and absorbs better than their Hyaluronic Acid + B5 which leaves a sticky filmLightweight & Affordable
Purchased this as I was new to the whole skin care scene, I really enjoyed how this felt. If you do not like heavier products this is for you, fast absorbing and affordable. Definitely a must for my skincare routinePretty good
Very watery and dries quickly but still leaves skin hydrated. Didn't cause pilling which I found the other The Ordinary hyaluronic acid does.Better than the original
I think I like this more than the original Hyaluronics by Ordinary. I feel like it's more moisturising, lighter and more natural. it's super lightweight but very plumping, I just feel my skin is rehydrated by this.Nice light product that doesnt leave a film feeling
Absorbs quickly and does not leave a film feeling or product feeling on the skin. Skin feels noticeably less tight and dry and less blackheads appearing from dehydration. *When applying this ensure that your skin is damp from a toner or essence. If you apply it when completely dry skin it can actually cause your skin to dry out more.OK
Watery texture but does a decent job providing moisture.Not sticky like the HA
I use this instead of The Ordinary HA which I find too sticky. This basically feels like water but I think it does a lovely job hydrating my skin.10/10
Absorbs easily like water! I use this every single day and don't see myself not using it. One of my favourite T.O products.Great for dry skin
This brand is the best, I love everything they doHighly Recommend!
This product is amazing, I wanted to find a less expensive alternative as I use HA morning and night, my friend who worked in skin care recommended TO and recommended the marine hyaluronics due to the other ones being too sticky, I was so happy with the product, this was two years ago and I just keep coming back, it's light weight, it's easy to apply, highly recommend!Lighter formulation
I have been using the ordinary hyaluronic acid for some time and love adding it to my moisturizer in the morning. I decided to give this one a try and have found it quite runny, making it more difficult to use. However I do like that is it not sticky, which other hyaluronic acid serums tend to be. I tend to drop this one straight onto my face rather than on my hands firstVery light and not at all sticky
I'm on my 2nd bottle of this because it's cheap and not at all sticky like HA tends to be. I found it boosted by hydration but if you're really dehydrated you may want something a little stronger.Hydrating HA
This is such a great hydrator and a wonderful alternative to TO HA, which I find too sticky and pilly when I apply. This has a water like texture and applies easily and soaks into the skin lovely. I use this after a few layers of a hydrating essence and before moisturiser and it helps everything sink in. Its a staple in my daily skincare routine.Good
plump and hydratedWatery texture
This is a good product for those who prefer watery textured serums. I prefer a usual hydraulic serum. It is better suited to my skin type. Still recommended!Amazing, lightweight hydration
This is an amazing product and I wish and hope that they bring it out in a larger size! This truly is as light as water but packs an amazing punch of hydration for your skin. Unlike other hydrating products (not all, but some) this does not leave any residue - no stickiness, tackiness, layer, film etc. This is incredibly enjoyable for those who may worry about their skin being clogged or live in h...Read MoreWatery compared to the standard HA
I bought this as the other HA product from TO would pill under my makeup, this is a more watery texture and is perfect for mixing with my L-Ascorbic Acid in the morning without creating thick layers of product.Too watery!
It's difficult to apply to face. I wasted so much of it at the beginning because it's just like trying to apply water droplets to your face. But I've started mixing it with other products on my palm before applying on my face.This formula caused extreme irritation
I have no idea why, but this formula caused a reaction on my skin. I did not have the same issue with the regular hyaluronic acid. I didn't really like the watery texture, I would prefer it to be thicker for the purpose of application. I had to use more product than I would have liked. After my skin absorbed the product it became very inflamed and started to sting. I washed off the product. I used...Read MoreThis formula caused extreme irritation

This stuff is seriously the best! Super hydrating and absorbs really quick. I personally love the watery texture of this product. I use this morning and night and 100% recommend. I have very sensitive skin and this product didn't irritate my skin at all.Absolutely an amazing product
I always need a hydrating serum in my skincare routine, I have tried the hyaluronic acid from the ordinary it was okay but too sticky so I decided to give it a try to this one... OMG it's so good, very lightweight, very gentle on the skin I highly recommend it for people who prefer lightweight serum as it just feels like water on the skinIt does the job
I purchased this to add more hydration into my skin care. I think next time I will try The Ordinary HA 2% rather than the marine version as I do find this one very watery and hard to applyLove it!
Love this for my combo-acne skin. It's super hydrating, but also really light-weight and water-like. Great for the drying winter months!Prefer others
After using the usual Ordinary hyaluronic serum, this was underwhelming for me. Not sure I noticed the difference from using it. Maybe I just prefer the thicker consistency, whereas this is very watery.Absolutely love this product
One of my go to products, it’s amazingNice
My skin seems to like it though I’m not sure if it works better then other things I’ve used. For the price point definitely worth it and I probably would repurchase in the future.My skin loves it
I have very sensitive skin that easily breaks out and I'm usually scared to try anything new on my skin. I read great reviews about the marine Hyaluronics serum by The ordinary and decided to try it. I must say that my skin loves it, it's super light weight and doesn't irritate my skin at all. The price is very affordable, the packaging is great and most of all there is no fragrance. Overall a gre...Read Moresuper hydrator
This HA is quite watery compared to the regular Hyaluronic acid sold by the ordinary. However I find this formula to be more light weight and easier to apply while still being very hydrating. I couldn't give this 5 stars as it isn't as effective in summer as it uses the moisture in the air. I still recommend purchasing this and it will definitely stay a part of my skincare routine.Great Source of Hydration!
I really like the watery texture of this product, it makes it so easy to distribute and spread out. It sinks in quite quickly and leaves skin feeling plump and refreshed.Lightweight & Hydrating
I didn't expect much from this product because of it's watery texture, however I did notice that once I applied my other serums & hydrators to my skin, I was glowy and plump! The only reason I haven't repurchased is because The Ordinary HA texture sits better on my normal/dehydrated skin. However if you're oily/combo/normal, I would HIGHLY recommend this product!Buy this over the Hyaluronic Acid!
I MUCH prefer this to The Ordinary’s Hyaluronic Acid which I found sticky and prone to pilling. In contrast, this product is water-like, absorbs immediately and isn’t sticky at all. I even think it has a superior hydrating and plumping effect on my skin compared to the hyaluronic acid.Lightweight serum
Great serum. There are some good and beneficial ingredients to this. It hydrates my skin and keeps it very smooth. It is very lightweight and a few drops go a long way!Better than Hyaluronic Acid
Absolutely love this product for adding instant hydration into my routine and plumping up the skin.
I personally prefer this for daily use over The Ordinary HA serum a it’s lighter more watery consistency Is better for my combo/oil skin. I love that it doesn’t leave the skin sticky like many HA serums are notorious for. I do use The Ordinary HA serum for Microneedling as it just works bette...Read MoreNew holy grail
I have been faithfully using the ordinary's original hyaluronic product for the past year and have only switched over to this product recently. While I didn't mind the tackiness of the original product, this one was far easier to work with and still delivered hydration. I am finishing off my last bottle of the original hyaluronic product and switching over to this one.Better than the HA
I have the ordinarys normal HA serum which is nice but it’s quite a sticky texture. I was told the Hylamide HA by the same company was better but Adore Beauty don’t have it so thought I’d try this. It’s a watery texture and it sinks in really nicely! Still moisturising like the HA but less stickyThis product was not for me
I had high hopes for this product as i have very dry skin and read amazing reviews, however, sadly it irritated my skin. I thought my skin may get used to it, but it just caused inflammation and stinging each time i used it. kind of a bummer, but might try and use it on my hands/neck area so it doesn't go to waste.My fave!
I don't like the consistency of the Ordinary's Hyualouronic acid - but this is a game changer. Not tacky and so light weight and smooth. Is so hydrating, absolute gem!Nice easy hydration
I love HA but find so many HA products are so sticky and sit on the skin. This is a water consistency and just disappears. Your skin drinks it up. I'm yet to see the super amazing hydration results but, my skin is accepting it and no breakouts so I will keep it up.Lightweight hydration
I love this as my AM serum (I use the HA + B5 at night). This is a well priced competitor to a certain brand in a blue bottle, I love how lightweight this is! Skin, and also my lips, looks plump and bounces back when I use this.This is beautiful
I love this. My skin drinks it up and its not heavy and can be layeredLighter than the TO HA+B5
It is lighter, less sticky and more watery than the TO HA+B5. It provides good hydration at affordable price point.Working well
Seems to be working well within my regime for my skinLove this
makes my skin feel so much more hydrated when I use this before all my other skin care items, it does what it claims!Excellent Product!!
I've been using this product everyday for around 2 years now and just love it.
It works
This product is so good & yet so inexpensive. Use directly after cleansing your face this marine hyaluronic soaks into your skin & leaves it soft & prepped for serums & moisturisers. Excellent product.Regular buying
Perfect for skin hydration at an affordable price. A go to in my beauty process. Love itLightweight and hydrating!
Switched to this product a little while ago after using the Ordinary's regular HA for a while, and not going back. The texture of this is much more fluid and lightweight, and so easily spreadable over the face - after a minute you wouldn't even know you put anything on! This product has definitely been helpful over winter to keep my skin hydrated.Moisturizing but not sticky
I purchased this product as a substitute for The Ordinary's Hyaluronic Acid 2% + B5 because it was too moisturizing and felt heavy on the skin. This serum has a light, watery texture. I have combination skin and I use this straight after washing my face while it is still damp and apply The Ordinary's Niacinamide afterwards. I only use this in winter for extra hydration or when needed for dry patch...Read MorePlumping and hydrating
I started using this serum as a substitute for the 'Hyaluronic Acid 2% + B5' and I have noticed a difference in how plump / hydrated my skin feels post application. I wouldn't say it is the best HA product I've used but it is certainly up there from an outcome and cost perspective.personal substitute for HA
prefer this over the HA + B5, personally find the consistency slightly lighter and absorbs better into my skin. Haven't noticed any outstanding differences that it has made thoughworking well
Seems to be working well within my regime for my skinFantastic. Love it
This is so nice!
I use it right after a shower, just after I towel dry my face. It soaks in and makes sure I don't get that tight feeling from a clean washed face.
It's a really nice texture (like water). It's lovely!Very light
I opted for this instead of hyaluronic acid to see which one I liked better. This is a really light texture like water but feels lightly hydrated i would recommend this for combo skin but me having dry skin i felt i needed a little more hydration. If you're looking for a light hydrating serum that is not too heavy this would be perfect for you.Love the texture
This product is water-based and absorbs really quickly right into your skin. I'm in love with the texture. Before this serum, I used TO HA + B5 and Hylamide Low moleculars and I found both of them are quite sticky. I have no problem with Marine <3.
Fyi, I have combination and sensitive skin.Best Budget Hyrdration
This hyaluronic acid serum work between a hydrating mist sandwhich (mist, 4-5 drops of serum, mist) and sealed in with a moisturiser. It adds a lot of hydration and keeps your skin hydrated throughout the day. This version from The Ordinary is not sticky and does not cause me any irritation. I cannot see a reason to bother with a more expensive hyaluronic serum when this one works so well.Light and hydrating
Perfect light consistency. Great as part of a layering routine or just for added hydration under moisturiser.
I prefer this to the other TO HA + B5.Thirst quencher
I tried this out because I found TO HA+B5 to be a little tacky/sticky, sometimes pilled/tingled. THIS serum was much better suited for my skin (combo,dehydrated/sensitive). A thinner, more watery consistency that is easier to spread. Didn't have the same berry-ish scent that TO HA+B5 product has but that is moot compared to how much better it was absorbed. Definitely feel the hydration+plumpnes...Read Moregreat under make up
The consistency of this makes it so good for under make up. It is watery and sleek, not thick and sticky so it just glides on and absorbs in quickly. Make up goes so smooth over it. It is quite hydrating and I find I use this in the morning followed by a hydrating primer and that's all the hydration I need for the day. At night though I use a thicker moisturiser.Drink of water for my face
I got this to try to see if I liked it more than TOs Hyaluronic acid + B5. This product is a completely different consistency it is water like and not at all sticky. It absorbs right into the skin and doesn’t leave any kind of residue (where as I felt like the other serum did).Drink of water for my face

It absorbs right into the skin and doesn’t leave any kind of residue (where as I felt like the other serum did).Hydrating but can be irritating
This oil is lovely and hydrating without making me break out, however i can feel it is definitely potent as sometimes my face feels a little itchy for a few minutes after I apply. the feeling does go away though and it doesn't make me irritated or red. I haven't seen any major changes but I do wake up with soft, hydrated skin. Great value for the price.Lightweight and hydrating
This product is a lot lighter and less sticky than the other Hyaluronic Acid from The Ordinary. I am currently getting used to strong retinols so my skin can get a little flaky sometimes. If my skin is peeling then this isn't quite enough and I use the standard version, but on a normal day as my skin can be oily, this is definitely enough and feels nicer on the skin and under makeup.Good boost of hydration
I purchased this to keep my skin hydrated, it's really watery so is a bit odd to put on your face but i've found it works and my skin stays hydrated during the day. Good to use as an additional hydration effect.So light!
I normally use The Ordinary's hyaluronic acid, but found it a bit thick.
I definitely prefer this! It has a more watery texture and is so light and hydrating.Super light weight hydrator
This is hydrating serum is perfect to use in the mornings under makeup. I have oily skin but also dehydrated, so it is great as it does not clog my pores. I could really tell the difference, and my skin always feels instantly hydrated after using. It is very watery in consistency, but absorbs really well into my skin. I have purchased two bottles!Lightweight and hydrating
I've used the ordinary's hyaluronic acid for a long time and picked the Marine Hyaluronics to try out. It is very lightweight, feels nice on the skin and makes my skin feel plump all night and day long. Excellent alternative to the ordinary's HA!Great alternative serum
I ordered this as an alternative to TO hyaluronic acid. I found that could sometimes be a bit thick for under makeup. This is a great consistency, very thin. It keeps my skin hydrated all day!Lightly hydrating
I liked this well enough, and the texture was beautiful, but I do think that my usual hyaluronic acid was more hydrating and it plumped out my skin moreBeautiful product!
I love this product! I prefer this to TO Hyaluronic Acid serum as its much thinner and doesn't leave my skin feeling sticky or cakey like the HA does. You do need to be quick when applying the product as it does absorb quickly. Really lovely product on the skin!Hydrating
I really like this product! I use it as a booster to add to my other products when my skin needs more hydration (and in particular, I use it after I use a hardcore exfoliating product). It has a really watery texture and settles into the skin really nicely. Great for winter. Would recommend!LOVE IT!
I'm brand new to The Ordinary and from my first use of this, I was in love! I also purchased a few other items from them such as the niacinamide and a retinol, but this is by far my favourite and I'll definitely be buying again. I have combination skin, with dry patches on my cheeks, and my skin just drinks this up soooo nicely. I don't find it has a scent at all, and it feels nice on my skin - do...Read MoreMight just be my skin
It may be my own skin that has reacted poorly. however when I use this product a do break out instantly on my forehead and in comparison to another brands I have used it had never happened.Nice alternative to the Hydraulic acid
Purchased this as an alternative to the Hydraulic acid as its not as sticky. It is more water based and easier to spread evenly over the face. Good hydrator when used under daily moisturiser.Inconsistent formulation.
I didn’t mind the first bottle of the this, but the second bottle was almost like a different product. Viscosity and texture were different and it seemed to be drying instead of hydrating. I find this is sometimes the problem with The Ordinary - although the price is incredible, the compromise seems to be inconsistent formulations.Good value
I thought I would enjoy the waterly consistency of the serum but I rather prefer the gel one. It gets absorbed quickly so good if you’re layering multiple serums. Good value for money, just like all The Ordinary products are.A+
I have tried so many TO products, and the one I was really not so happy with in the end was the HA+B5, even though I have gone through a couple bottles. I finally realized the gel consistency is not that great, and it doesn't absorb very well at all. This formula is so much better, similar to the NIOD version with its watery texture, and really really does help my skin retain moisture. For the pri...Read MoreWater consistency but much prefer over other HA
I had been using TO HA+B5 for a long time and really liked it, I now much prefer this product even though I thought I wouldn't like the watery consistency. It layers better with other products, I just wish it came in a supersize jar like buffet and HA+B5! I've also accidentally got it in my eye and flushed it, but experienced no redness or irritation in my eye which was a relief.Perfect
Very light, compared to the other hylaraunic acid and works just as well. Can't wait for a supersized version.Best ever product I bought
I am so satisfied with this product ... I have spent so much money on so called elite brands ... but ordinary just did the job right ... I love itskins straight in
This product sinks straight into your skin after your cleansing step. I use it in combined with the Hyaluronic Acid 2%+ B5. its my AM & PM nightly staple and its water texture means it gets fast absorption into your skin. Ive never had a reaction and dont find there is any smell. i really like it around the eyes as its easily absorbed .Traps moisture and keeps me looking fresh
I use this in the more humid seasons and it makes my skin look fresh and glowy. Would definitely recommend for dry skin.Impressive hydration
I have oily dehydrated skin, and I wasn’t enjoying the texture of hyaluronic acid so I thought I’d try this, and I’m so glad I did! The texture is like water, but it is SO incredibly hydrating. Love it!Beautifully hydrating
FYI I have mature dry sensitive skin. It took a long time to realise my skin didn't look dry because of my makeup, it was lacking good hydration in my skincare. I ordered several TO products and I love this!! I use it twice a day by pressing it into damp skin before serum and creams. It maybe the whole combination of products but my skin is FINALLY looking much less dry and dullDoes the job
I tried this before I got Hyaluronic acid and it apparently does the same thing but is in a thinner and more lightweight consistency, this would be good for applying in the mornings if you dont want a lot of heavy face products but still need hydration. I liked it but i have switched to Hyaluronic acid now just as it seems a bit more hydrating.Nice and lightweight
Nice and lightweight on skin. I’ve noticed a positive difference on my skin since I added this to my routine - before serum and cream. My skin feels more hydrated.Better than TO's Hyaluronic Acid + B5
Hyaluronic Acid + B5 has serum-like consistency but sticky which I'm not a fan of.
Marine Hyaluronics, however, is different in terms of its consistency. It's watery and not as sticky as Hyaluronic Acid + B5
Hero Hydrator!
My skin LOVES this! I have super dehydrated skin and this is like a cold glass of water on a hot day. I have tried The Ordinary’s other HA serum and this one in my opinion is far superior. I can definitely see a difference in my skin since using this. Hopefully they supersize this one!Great
Lightweight, refreshing, makes other stuff go on better.Light hydration
Light hydrator that i use in conjunction with the Amino Acids from the Ordinary. Leaves a nice feeling, especially during the summer months when you don't want heavy serums.Great!
This is very lightweight. I tried the standard Hyalauric acid from the ordinary, which was still good, although this formula spreads on better. Will be buying again!Feel nice
A pleasant Hyaluronic Acid to put on the skin in the morning after the cleanser and before any other skin product, it provides great hydration, it is very liquid like water, light and fast absorbing.Great hydratation, not that easy to apply
Very liquid, so harder to apply without wasting product. But provides great hydratation, makes my skin plump. I use it as a carrier for my vitamin C powder.An essential!
As a hyaluronic acid should be an essential, it was important for me to find a good economical option but one, that performed at an optimum. This one is highly rated amongst the experts and feels great on the skin.
Being the first step after cleansing, this works beautifully and I never have any issues or pilling when layering.
Love it!Great hydration boost, layers well
Provides great hydration in the morning before applying rest of skincare & no/minimal pilling under makeup so far. It does have the faintest scent which reminds me of seawater but barely noticeable and it goes away fast (especially if wearing other skincare and makeup on top).love love love
I decided to give this a try as an alternative to TO hyaluronic acid because I was sick of its gluggy consistency and pilling. I much prefer the lighter consistency of this serum, it feels like water basically. It goes on so much smoother and sinks in instantly. I would definitely recommend this for oilier skin types.
