Have been using morning and night for a few months now and am loving it. Leaves my skin feeling hydrated and plump, has a nice smell. Would recommend

strong scent


It does its job- hydrating the skin. However it leaves a sticky feeling afterwards as it doesn't seem like got absorbed quickly. I also personally didn't like the strong scent.

  2. Works well


    I expected the serum to provide hydration and that’s all I expect from hyaluronic acid. This one does it perfectly for me. My skin is hydrated and plump. It says added scent but I don’t find it strong. I am not sure how much to worry about the alcohol content. It doesn’t irritate my skin!
  3. Lovely product, but..


    I loved this serum when I purchased it. Feels great on the skin, don't have to wait to apply products on top, ticked all the boxes of what a good hylaluronic serum should be UNTIL l came across the alcohol content which is particularly high. Regrettably not for me.
  4. a good serum


    Hydrating & plumping - it's lightly fragranced which has not yet caused any irritation to my sensitive & allergy prone skin. Slightly tacky to touch when dry but not something that bothers me
  5. strong scent

  6. Great serum


    verified purchaser
    Had really amazing results with this serum.
    Face is more plump and hydrated
    Love it
  7. Good


    I have oily, sensitive, acne prone skin so not much is compatible. My skin soaks up this product nicely but I find the product to be sticky. I do love the packaging though.
  8. Great hydration


    very good hydrating serum with nice scent but not overpowering
  9. Repeat buyer


    I love this product.
    It melts into the skin, feels so hydrating and im onto my 4th bottle.
    Its great for sensitive skin, a great price for hyaluronic acid.
  10. It's good, not great


    I decided to give this Hyaluronic Acid a go, mainly because of the affordable price. It feels great on my skin, is a little sticky but absorbs nicely, but I was disappointed I didn't look close enough at the ingredients and missed that it is fragranced... smells lovely, but I wouldn't normally put perfume on my face so I don't want it in my skin care routine. If they took out the fragrance I would...

  13. Fabulous!


    I love how this serum hydrated my skin. Due to the Covid-19, I have to wear mask everyday at work, my skin just so dry constantly. Since I use this serum under my moisturizer, it stopped the dryness and give my skin a nice glow looking. Must try product.
  14. Great Serum


    I bought this with the La Roche-Posay Vitamin C and Retinol serums and it has been great to have a hydrating serum and I can really see the difference in my skin. I really like the fragrance and I find it soaks in really quickly
  15. Hydrates with water gel


    Leaves a nice glow, seems to hydrate. You need to leave it to sink in before applying makeup as it’s a little sticky.
  16. Strong scent


    I use this serum before my moisturizer and it hydrates my skin and gives it a nice glow but I will not repurchase because of the strong fragrance.
  17. Good hydration


    I've been using skin critical B5 , it is expensive so tried this and have seen pretty much same results in hydration. I use this in conjunction with my Dermapen treatment as you need something that's a hydration gel to glide the Dermapen over and pump in the moisture.
  18. Best hylauranic serum


    I'm now on my second bottle. Skin is plump, soaks in fast (remember to apply a mist first so it's not drawing water from your skin) and no nasty smell. Doesn't leave the skin feeling oily, just hydrated, smooth and plump. Highly recommend.
  19. great


    i use this under my moisturise and it works really well. you only need to apply and small amount as it goes a long way
  20. Lovelovelove


    I bought this on a total whim... and so thankful I did! Love the scent, the feel, the effect on my skin. Water-based and cooling when it goes on, smells as refreshing as it feels and soaks up into my skin , leaving me to get lots of compliments the next day!
  21. Loved it, will buy again


    Loved this product. It has a nice matte finish and makes my skin feel taut and fresh. I really noticed a difference in my complexion. Will definitely repurchase!
  22. Plump


    Hyaluronic acid is great at plumping skin so I love to use this under moisturiser and makeup
  23. Best Hydration at a reasonable price!


    I absolutely love this product! It feels so smooth and silky on the skin and adds instant hydration to the skin. For me personally I don't use it every day, as my skin is not overly dry, so I tend to use it alternating nights with my retinol. My skin feels more plump and soft since incorporating it into my routine.
    In regards to the 'dropper' prior to using La Roche Posay, I hated dropper bo...

  24. Leaves Skin Juicy


    I do enjoy how quickly this serum soaks into my skin and leaves it looking juicy and plump. Works best on damp skin.
  25. Too fragranced and sticky


    I had high hopes for this product as I have been using other products from La Roche and loved them.
    I am disappointed with this product, it’s super sticky on my skin and it is way too fragranced it just doesn’t feel right.
    I’m yet to notice any positive results but I’ll keep using it as I’ve spent my money on it. I unfortunately won’t be buying it again. There’s a lot more nicer prod...

  26. If you want smooth, hydrated, glowy skin...get this serum!


    I am very impressed with this beautiful serum. My skin feels and looks smoother, plumper and very hydrated which gives it a nice glow. I have used high end skin care and I must say, this serum is right up there. I haven’t tried the Vitamin C serum but that is my next purchase.
  27. Amazing!


    I love this serum. It sinks in quickly and doesn't leave any sticky residue. It is very hydrating and doesn't make my sensitive skin break out. It lasts a long time too. Will buy again.
  28. Plumps


    I’m enjoying hyaluronic acid applied to damp skin to plump and hydrate but it is hard to justify the price of this one when there are much cheaper alternatives with the same ingredient
  29. Moisture Booster


    This adds a nice boost of moisture to my skin each morning. I've used other, more expensive brands, but this one seems to be doing a nice job. It does feel a little thick and sticky coming out of the bottle/pipette but it applies nicely to damp skin and the texture hasn't been an issue for me.
    My skin is quite dry and deyhdrated now that the winter weather has arrived and this is definitely...

  30. Beautiful hyaluronic acid addition to any skincare regime


    I’ve been using this serum twice daily for the past three weeks and I absolutely love it! I apply it to damp skin after cleansing AM and PM and I’ve found that it has definitely improved my skins hydration levels. Please note, it is really important to apply the serum to damp skin to avoid pilling!
  31. Super Hydrating


    This serum is so hydrating! Sometimes I get a little flaky in certain parts of my face but since using this, my face is so hydrated and no sign of dryness. I like to use it at night as it is quite a heavy texture so I’m unsure how it would wear during the day under makeup.
  32. Good source of hydration


    This is a good, basic serum if you’re looking to hydrate dry and sensitive skin. The only downside is the fragrance. It works well but there are similar products at a lower price point.
  33. Freaking amazing


    This serum was like brand new skin in a bottle. I know very little about skin care, but I got this in a sale and it was so hydrating and made my skin supple and radiant. Would recommend, but is quite pricey so can't buy outside of sales
  34. Big Fan


    I love anything with hyaluronic acid and this product is no exception. My skin looks brighter and feel plumper
  35. A bit sticky

    Bridget L

    This was my first love of Hyaluronics - I would put it on at night and in the morning my skin would be really soft. The only thing is I do find it is a bit sticky and now after using The Ordinary's version, I won't be going back.
  36. A great hyaluronic serum


    Really penetrates my skin and leaves it plumper and retains more moisture. I normally use the Ordinary hyaluronic serum but this one seems to pack more punch to make it worth the extra money.
  37. Beautiful!


    This product is amazing and is making a big difference in my skin. Is rapidly absorbed and after a week I could already feel my skin firmer, brighter and plumped. I recommend using it with the Vitamin C also from La roche Posay. Its a must have in my skin care routine. My skin was never this radiant.

  39. Fantastic serum to plump & hydrate my skin!


    I have been using this serum for 2 weeks now & love the hydration factor!
    And plumping to my skin is not just noticeable to me - my husband has even commented & that is saying something :-)
  40. A Hyaluronic with Results


    I bought this product as an upgrade from The Ordinary version which wasn't doing anything for my skin. I apply this after a mist in the morning and have definitely noticed my skin feels plumper and more hydrated after using it, so will continue purchasing.
  41. good for sensitive skin


    this serum is pretty good and i do feel like this product makes my skin feel a little more plumper after using this and the good thing is that it didn't affect my sensitive skin
  42. Better than their vitaminC serum


    Ok - i have given this atleast 6 months before reviewing.

    Still undecided.

    Haven’t seen any claimed result and very sticky after residue never gets better.

    Pursued with half the bottle and has been sitting aside collecting dust since.

    But it is better than their Vitamin C serum
  43. absorbs immediately


    this absorbs well and does make skin feel plumper and hydrated. It's costly but I do think it's worth it
  44. I dont get it


    i do not understand why this product has perfume in it??????
  45. awesome!


    so hydrating I love it
  46. One of the Best!


    I love this stuff!! I use it religiously! It gives my skin that extra hydration it needs and plumps the skin leaving me looking fresh and hydrated AF! I pat it in after using a mist, and before my moisturiser. I like to let all my skincare soak in to my skin properly before makeup and this gives that extra bit of glow to my skin so I don't look dry and crusty. Even on days I have no makeup on, I j...

  47. Love the texture of this serum


    I have dehydrated skin so this has been a great product for me. I use it day and night. A little goes a long way and it leaves such a nice smooth silky texture. I have been using it together with La Roche Posay's vitamin C serum and have noticed a huge difference in my skin.
  48. Beautiful & hydrating


    This serum feels amazing, it does exactly what it promises. Hydrates and plumps beautifully! I use it morning and night with other LRP products and won't ever be without it!
  49. Pricey


    It is a very hydrating serum granted that you top it off with a nice moisturiser however I recommend trying out a cheaper hyaluronic acid serum to see if the ingredient works for your skin before investing in this pricey serum.
  50. Love it. Works as well as more expensive versions.


    I replaced my really expensive Hyaluronic serum with this one because it's a bit more affordable. I'm so pleased that I did as I've found this one works the same, if not better.
  51. Super hydrating serum!


    This is an amazing serum for very dry skin. I use it at night sometimes in place of reship oil and let it sink in for about a minute before applying my moisturiser. I always wake up feeling soft, supple and have a dewy glow!
  52. Great


    This really helps my dry skin and makes it look plump. Will purchase again when finished
  53. Find better


    It smells good and blends into the skin well, however after a few days I was getting a reaction to it. Wouldn't recommend it.
  54. Immediate results


    Immediate hydration upon application. Just seal the hydration in with a thicker moisturiser
  55. smells nice


    This product smells better and has a different consistency to others that I have tried in the past. It has a light, fresh feel when using it but does take a minute to soak into the skin.
  56. Excellent hydrating serum


    At first I thought this serum was too sticky, but I just wait an extra 30 seconds or a minute before I put on moisturiser and it gives it time to soak into my skin.
    This serum is amazing - it provides extra hydration and is wonderfully anti ageing for my 40+ year old skin. This serum does exactly what the label says it will, which is why I am on my fourth bottle and also have my husband usin...

  57. Stickiness


    Even though it can hydrate my skin, the texture of this is too sticky!! It is also not good for makeup, so I only use it at night.
  58. fragranced

    Lilac Pangolin

    This is really nice, texture and hydration wise its perfect to me, but it has a perfume which smells very unnatural like a blue "ocean breeze" candle or something. It also stings my skin when its very fragile and red, I guess this is the perfume? But nobody has time for that. A simple hyaluronic acid is sometimes all I will do when my face is sore or irritated, so no thankyou.
  59. Hydrating


    This serum really hydrates my skin and reduce flaky skin.
  60. Good


    This is great for hydrating my skin but prefer if it was fragrance free
  61. Feels luxurious


    I love this serum. I use it every night as part of my routine and it feels so nice on my face. The texture glides on and is really easily absorbed, it feels so much more expensive than what it is. It sits nicely underneath other serums/products. I will definitely buy again and again.
  62. love this serum


    a lovely serum that doesn't break me out and is easily absorbed into the skin
  63. Nice but doesn't do anything for my skin


    This is a nice lightweight serum but I don't think it makes a difference to my skin at all.
  64. LOVE IT


    I love this product - it smells amazing, absorbs well and keeps my skin hydrated

    I have tried many different Hyaluronic Acid serums, and this is one of my favourite. I have very dry skin and this keeps my skin feeling hydrated all day!

    It has a bit of a scent to it which I like but those who don't like scents may not like this.
  65. Great


    THis really helps with hydrating my skin. I use it every night
  66. Plumping Redness


    I have been giving this product a good go because I do believe it's a good products. It goes on really nicely and feels like it goes in. And your skin does feel refreshed and plump the morning after. It's a great product to travel with given the dehydrating action air travel can have. However for some reason it activates my rosacea.
  67. Great


    My skin is dehydrated during the winter season but after using this for a few days I can already feel my skin is more hydrated and less dry flaky skin. Definitely love the product.
  68. Life saver


    My skin use to be very dry, but after using this for a few weeks, my skin feels so much more softer and hydrated. In the beginning I was applying it day and night, but I find the product to be a bit sticky, so I just apply it before bed, and it's more then enough. Will definitely be re-purchasing.
  69. Intense hydration


    This serum gives my skin instant hydration. My skin feel so soft and smooth the whole day. The texture is not too thick so its very easy to absorb. It is the perfect product for me during winter season. Definitely repurchase.
  70. beats super expensive hydration serums


    This is the best hydration serum I have ever used. It layers so well with my other skincare morning and night whilst providing intense hydration. I really like the consistency of this product too, it isn't too watery.
  71. Great hydrator


    I love this hydrator, and it doesn’t irritate my sensitive skin. I tend to use it at night as it doesn’t layer too well under my sunscreen and foundation.
  72. Best one I've used


    I have to say I really wasn't sure about this serum for a long time, but it is the best one I've used. It has such a nice scent, and feels lovely on the skin. I do find that if I layer the La Roche Anthelios sunscreen on top of this serum it can pill especially into my hairline, but I've recently switched sunscreens and now don't seem to have that problem. Noticeable difference in hydration to my ...

  73. The most effective serum for hydration


    This is the most effective serum for everyday hydration I have used. And I have tried a few. It's quite pricey when compared to the rest of their range but you can feel every penny of it on your skin. Plumping, hydrating, smoothes fine lines and goes on like a dream under SPF and makeup.

    Currently my favourite serum, this has a luxurious texture and leaves my skin feeling silky smooth and hydrated. I also really like the scent. I would highly recommend this serum. I have been using it morning and night.
  79. Hydration plus!


    This has completely renovated my skin. I have normal to dry, super sensitive skin and I have zero irritation with this.

    It has markedly reduced the pigmentation in my sun spot which I've tried a zillion products for. My face feels hydrated all the time.

It was light enough to put on before bed without feeling oily and leaving a mess on my pillow. ...

    Every time I use this serum at night, I wake up with dewy, glowing and smooth skin. My skin always looks very fresh and plump. I absolutely love it

    I have been using this serum from past few months, little goes long way.. i m not a fan on its texture but you guys it’s definitely does what it claims. I have noticed visible change in my skin’s texture, I would definitely be repurchasing this.
  91. deep moisture but could do more


    this hyaluronic serum is highly purified and does nothing more than provide moisture. it is recommended for all skin types as it provides all the essential deep moisture for the skin and absorbs relatively fast, however, for the price marked for a serum, it definitely can do more than it does now
  92. So good!


    I love this brand and decided to purchase this product, so happy I did! The smell and texture of this serum is lovely, I apply it at night after my vit C and its the perfect combo, I wake up with plump smooth skin.
  93. Love!


    I received a sample of this product and love what it's done to my skin already and it's only been a few days! My skin tone looks more even and fresh, going to buy more
  94. Bouncy Skin

    Lilian D.

    I love this hyaluronic serum more than The Ordinary's hyaluronic serum. It is more dear but i think it's worth the money. It gives the skin this bouncy plump texture when you wake up and i can feel like there is more moisture retention. Definitely will be repurchasing this one!
  95. Smells better than the cream version


    I really didn't like the smell of the hyalu b5 cream, thankfully the smell of this is much subtler and tolerable. It is very runny, so be careful when you first start using it. It didn't cause me irritation, however I didn't see great improvements either. Certainly didn't help with my deep neck lines, might work better on superficial wrinkles but they aren't an issue for me yet.
  96. The perfect product for lots of hydration without oil.


    This is a lovely hyaluronic acid product. Your skin will feel lovely and smoothed out. You will feel nicely hydrated, plump and glowing. I can feel when I don’t have it on.

    I find this is nice for hyration and a slight plumping effect to the skin but I'm not a big fan of the smell so might shop around for my next hyrating serum. No adverse effects it just smells sort of chemically/alcoholic
  100. Very hydrating and gentle on sensitive skin!


    I have made this product an integral part of my skincare routine. It is so easy to apply, so very hydrating and works very well in combination with other serums (e.g. Vit C suspension from The Ordinary). My skin can be somewhat prone to irritation but this product caused zero flare-ups - if anything it calmed my skin! Very keen to repurchase.
