  2. Love this!

    Mel

    My favourite hyaluronic acid serum! Have repurchased this a few times now. I like how fast it absorbs and how there is no tacky feeling like with some hyaluronic products. Also sits well under makeup. I use this every morning and evening after washing my face - would recommend! Have tried cheaper products but don’t feel they work as well as this one.
  3. Juicy, and nourishing for my skin

    Alice Feez

    verified purchaser
    This is refreshing and plumps my skin up, so its nice and juicy before applying makeup. It feels a bit tacky after application and i often feel like i need moisturiser post-application. In the case of makeup application, this wokrs wonderful, as it holds onto my foundation, prolonging the wear as my skin is hydrated.
  4. Hydration powerhouse!

    Kirsty

    verified purchaser
    I use this serum day and night, I am totally addicted to it! It hydrated like nothing else! I highly recommend this product as a must have in anyone’s routine.

    Best serum for hydrating the skin and giving t a beautiful glow. Leaves it feeling very smooth also
  6. Must for summer

    Shun

    This is a must for summer to balance the extra oil in the skin with hydration. You will see results immediately, i also mix it with my vitamin c serum

  8. Sinks In Beautifully

    Jo

    I received a sample of this but I already have the hydra8 b5 intense that I bought from Adore at beginning of this year however, I found this version to be much better at hydrating my skin. This one sinks in beautifully, is not sticky and feels so hydrating whereas the intense version is sticky and sits on top of my skin. Will purchase the full size of this one as soon as I use up the intense vers...

  9. Amazing hydration!

    ALS

    I have combination oily skin, and with a better skincare routine from my beautician, it is now normal-oily. I’m converting my makeup to Jane Iredale and Youngblood, as I found the foundation I was using (The Body Shop) looked amazing, but left dry patches on 2-3 prominent areas on my face. It took me a while to understand the difference between having oily skin and having hydrated skin. Once I tri...

    Jayde

    Love this so much! super hydrating and makes my skin look more glowy! prefect to use before applying makeup for that youthful glow!
  12. Hydrating smooth finish!

    Kirsty

    This product is beautifully hydrating and the finish is beautiful and smooth and not at all sticky, can be worn under make up as your skin drinks this up!
  13. A definite must-have!!

    Donna

    I bought this when starting out in my skincare journey, shortly after listening to the podcast episode with the Medik8 specialist. I have always had dry skin and this has changed that! This put my skin into a hydrated state to actually start using more active ingredients on my face without reaction.
    It is also amazing for after microneedling/microdermabrasion for repair, hydrating and calmin...

  16. No change

    Jane

    Unfortunately I haven't noticed any change in skin hydration since using this serum for the past 3 months. It goes on nicely but doesn't seem to have any lasting effects. I won't repurchase
  17. yep love it!

    amanda

    this is one i now won't go without. i got a sample of this and fell in love overnight. it leaves you feeling soft, smooth and glowing. Definitely one of the better quality hyaluronic b5 products on the market. you really get what you pay for with quality and i won't hesitate in dropping a little extra cash for better quality stuff. I use 4-5 drops for my entire face and neck, goes on so smooth, i ...

  18. Meh

    Kim

    To be honest I'm not sure this product is doing anything for my skin. I was expecting it to be more hydrated and glowy but it is only like that when I first put on the product and doesn't last. I won't purchase again and it didn't blow me away. I don't mind paying $$$ for good skincare - if it works.

  20. Very hydrating

    Ramona

    I have very fine lines and have noticed my skin losing moisture and elasticity recently. This serum has helped with the appearance of these early signs of ageing. It applies very smoothly and disappears into the skin leaving no sticky residue.
  21. Light weight

    Liss

    Received as a sample and I liked it so much that I purchased the full size. It's not world changing but it's a quality product for a good price. It's hydrating and lightweight and with my acne prone skin it caused no irritation.
  22. Lightweight and good for my combination skin

    Estelle

    I have a oily combination skin and this product doesn't cause breakout and it keeps my skin hydrate for the whole day.
    Nature smell and simple ingredients, keep my skin healthy.
    Compare to Skinceutical B5, this one is more affordable.
  23. Hydration

    Lee

    Feel skin smoother and hydration ,and no breaks outs
    Will buy again
  24. Great starter

    Bree

    I have normal to oily skin. I bought this an an intro to face serums. It’s a great starter. Whilst it’s both gentle and hydrating I will consider moving to retinol after going through this bottle. Goes on nicely and feels lush on the skin.
  25. Awesome and not sticky

    V

    So
    First time trying this brand and product and absolutely loved it! Not sticky at all but thick enough for it to feel effective! Layers well with makeup and other skincare. The little tube thing actually has measurement on it to let you know how much you are using - very helpful. A little also goes a long way, I don’t use as much as the recommended amount, half is sufficient to cover my who...

  26. Hydration in a bottle

    AJW

    Ahh this serum is fab! It’s hydrating and easily absorbed into the skin without leaving a sticky feeling, easy to apply other products on top of it too. I’ve just changed over from ASAP B super complex and not looking back.
  27. AMAZING

    Loll

    I LOVE this product. I bought this during the 15% off top 10 AB sale lately; it's amazing. Soaks in so easy. Decent size. Not sticky or tacky. Will do an update review in a few months to see further results.
  28. incredible

    raz

    This is a wonderful way to try the range! I always take it with me when I’m travelling, great for the plane!
  29. Love this serum, keep coming back to it.

    Medik8 Hydr8 B5

    Have used several HA serums and I'd have to say that this has been my favourite thus far. I recently switched to another highly rated HA after using this one for a while and this one still comes out on top. I have combination skin with a bit of post pregnancy rosacea and I find this feels really nice & hydrating (without being too much) on my skin.
  30. Can't live without it!

    leah

    I was happy to add this to my skin routine. It has been the only hyaluronic acid ive tried but I feel like it gives my skin a big "drink" which makes it plump and seems to smooth everything out. I only apply5 drops and it makes SUCH a difference. Won't ever try any other product this is perfect
  31. It's OK

    Abby

    Received a sample, won't buy the full size. Too expensive for just average performance. But it's good to try for sensitive skin people because it's really gentle
  32. Handy hydrator

    M

    This serum is great for me on days my skin is feeling a bit irritated or sensitised. It layers well with other products and hasn’t broken me out.
  33. Skins best friend

    Janet05

    Used this for 5+ years, then thought id give it a change and use the Drunk Elephant B-Hydra serum, and regretted it. Went back to this product and have been using it since. Its got a better packaging than the Drunk elephant, less creamier so you can easily combine with a vitamin c or other serum. Results after one application and on the spot!
  34. AMAZING

    jjunkd

    this is pricier for a HA serum but I LOOOOVE this because a) it lasts a good three months with twice a day use since you don't need much and b) its extremely cosmetically elegant as it is one of the few HA serums that dry down and don't stay sticky. I love this and I've already bought another one!
  35. Liquid gold in a bottle!

    Viki

    Absolutely love this product! I have been using it for over a year alongside the Medik8 clarifying foam and balance moisturiser. It provides instant hydration to my skin and leaves my skin feeling soft and smooth. Worth every cent!
  36. Immediate results

    jlz8

    You put this on after you wash your face and honestly you will feel the results instantly. I wouldnt use it on its own, and definitely need to seal in the hydration with other serums + moisturiser as soon as you apply it. I use it together with my Vitamin C serum and its so hydrating.
  37. Love

    Nickole

    High recommend to use with Retinol .6% serum and C tetra in the AM & PM.
    Your skin feels hydrated straight away after putting it on.
  38. Rehydration

    Kathleen

    This really does help hydrate your skin! fast absorbing!
  39. Sooo hydrating!!

    Maree

    This serum is a must have! It is so hydrating and will leave your skin smooth glowy and looking beautiful
  40. This serum is a must in every girls skin routine! I’m on my third bottle & absolutely love it .

    Manda

    This product Hydrates & keeps the skin looking moisturised.
  41. Skin feeling softer and looking plumper

    Lels

    Having read all the reviews, I decided to give this product a go as my first serum. I apply at night before moisturiser and have to say, I love the results. My skin feels softer and appears to be plumper in the mornings. I feel like after a month, my skin is looking soo much better. You only need to use a very small amount, so the pricetag is worth it.
  42. Skincare regime must-have

    misssarai

    This is the best serum that I have tried. It's a light-weight formula that's hydrating and doesn't clump when layering other skin care products. I use this morning and evening after applying my Medik8 C-Tetra Serum.
  43. No sticky finish

    beautygal

    I received this as a sample. I don’t feel this is the best hydrating serum out there, but I love how it leaves behind no residue or sticky film, goes well with skinstitut moisture defence normal.
  44. Does the job

    Chris

    I received this product as a sample and I enjoyed using it. It hydrated my skin really well and made it supple whole using it with my regular moisturiser.
  45. Very Hydrating!

    Renee

    An amazing serum which did a great job o hydrating my dry skin! I apply it before bed and wake with glowing, soft skin. It also wears well under make up to ensure my face is well hydrated throughout the day. Absorbs well and my skin loves it!
  46. Skin slurps it up!

    Louise

    I can’t live without using hydrating serums! I was using ultraceuticals B2 before this. I feel they are comparable and I love that medik8 absorbs super quickly instead of having to wait a little before applying other products. So far I’m impressed and happy with the ingredients!
  47. Super hydrating

    Jaimi-Lee

    Love this serum! I was recommended this at a skincare salon to help with hydration. It is extremely hydrating, lightweight and soaks nicely into the skin. Great to use before your moisturiser and a little goes a long way. Definitely worth the cost.
  48. Lovely hydration

    Ms Z

    I recently received this sample and I really loved it especially now for winter has my skin was really dry it plumped my skin and wasn’t heavy at all. Still have some left has a little goes a long way.
  49. Hydrates and plumps skin

    Elizabeth

    I have been using this product for years! It is my go to product when my skin is feeling on the dry side, particularly during winter. I use this product in conjunction with a vitamin c serum (medik8 also) and the results are amazing. My skin feels hydrated and plump and my skin does not feel oily at all (I have oily/combination skin). Would definitely recommend!
  50. Super lightweight but hydrating

    ZYE

    I really enjoy this serum! It is super lightweight but keeps my skin hydrated. Amazing product!!
  51. Hydrating and NOT sticky

    Austen

    This serum is perfect if you are looking for a simple hydration step in your routine - it does not leave sticky finish on the skin and I notice an instant plumping effect after it has absorbed. This works amazing if applied following the Medik8 Vitamin C serum and onto wet skin too as it locks in the hydration! A must have!!
  52. must-have

    Bonnie-Jade (Adore Beauty Staff)

    This serum is a game changer! Best HA I have tried. Provides instant hydration, is lightweight and easy to add into any routine
  53. Hydration

    Emma

    I have really dry and dull skin during winter and trying to find something that isn’t heavy on my face was really hard! Then I found this product! I use it every day and night and my skin has never been more hydrated and soft! The oil is not greasy as you would think it would be. A definite must have for your skin care regime
  54. So lightweight and quick absorbing

    Khim

    I received a sample of this and liked it. I was surprised at how quickly it absorbed into my skin and it has great spreadability so a little bit goes a long way. There was no stickiness or tackiness like some other serums. Keeping an eye on this one once my current serum runs out.
  55. Love it!

    Adina

    Received a sample of this ages ago and have used it predominantly as a serum after double-cleansing to remove makeup since I've found it to be more calming on my skin than all my other serums! Follow it up with a face oil (The Ordinary Borage Seed) which glides on smooth after the serum, and in the morning my skin is taut, smooth, and super clear..which is rare for me haha!
  56. Love this product

    Jessica

    Got this as a sample from Adore with another purchase. I have combination skin that can get very dry but moisturising at night usually causes breakouts. This product has absolutely saved my skin and I have stopped breaking out. I’ve noticed my skin is glowing and my fine lines have disappeared. It soaks in to your skin straight away. I will not go without this product in my routine ever again.
  57. Hydrating

    Brooke

    Received as a sample, will be purchasing the full size after trying the sample!
  58. Love this!

    Lauren

    I love this serum so much! I got this as a sample and I have fallen in love with it. It makes your skin so smooth and dries super fast, and it's not sticky at all. I just wish this wasn't so expensive! I don't know how I'm going to go without this now.
  59. My favourite serum

    Erin

    This has been my overall favourite serum. I'm just about to try Medik8's stronger B serum, but honestly can't imagine it being any better than this.
    It absorbs straight away and goes we under makeup.
  60. Love

    Kylie

    Medik8 is one of my favourite high end brands. This serum is nice, but just being a basic vitamin b serum I wonder if it's worth the price tag
  61. Lightweight and hydrating

    Tanya

    Received a sample of this. Pleasantly surprised. I have combination skin (which gets really dry in winter) and I feel like I have to choose at nighttime between leaving it dry or risking spots in the morning. Used this before I went to bed and was really happy. It was really lightweight and soaked up without leaving any residue. Just felt really nice on my skin. Skin looked nice in the morning and...

  64. Just love this serum!

    Rachel

    I have combination skin but tends to get quite dry in winter months. Hence, extra hydration is a must. I received this product as a sample. Although, I have used this product before and have loved it, I just found it too expensive so I didn't repurchase. Now that I have used the sample, it has just reminded me how good this serum is. It provides the hydration I need, brightens and smooths my skin ...

    I initially received a sample from AdoreBeauty and I thought it was nothing amazing. However, I decided to give it another try (blame the reviews!) and bought a full sized bottle. You know what? I loved it! I have been using Vitamin C serum during the daytime, and this is the perfect serum for a nighttime. Loving the result so far!
  66. Hydration dream

    Jessica

    I recently received a sample of this Serum, I’ve been using it at night time on my combination skin, I found a flash my skin more hydrated and smooth looking.
    I would definitely consider purchasing The full size products in the future.
  67. Hello Hydration

    Kimera

    This is a great staple and after-cleansing step. I always spray a water-mist after using this, just to ensure it pulls moisture from the out-in, not the other way round!
    So soothing and a quick dose of deep-hydration.

    I removed a star because once you discover the Medik Hydr8-Intense, this product shines a little less. - BUT this is still a great product, and I would always su...

  74. I am onto my third bottle!

    Laura

    100% lightweight and fast absorbing. I am prone to oiliness if products are heavy and the serum makes my skin feel soft and plumped. I’m into my third bottle and one of the best hydration serums I have used. Highly recommend!
  75. Wonderful!

    Donna

    My friend who has been using and loving this gave it to me to try, will definitely be purchasing!!! Soothes and hydrates my skin!
  76. Soothing and hydrating

    Lauren

    This is a lovely serum! It feels really soothing (think that's the b5?) and the hyaluronic doesn't feel too sticky on the skin. I mix it in with a C serum occasionally on damp skin. Works well under my sunscreen and makeup.
  77. Just like the old one

    Julie

    This is a new one with more ingredients, as the old one was purely hyaluronic acid. But works just as great if not better because it doesn't evaporate as quickly.
  78. Medik8 B5

    brooke

    I have very dry skin and this product helps so much! Makes my face feel so plump after every use!
  79. Love this product

    AC

    I have been using this product for over a year now and definitely noticed a difference in the hydration of my skin. I have combination/ dry skin and this product paired with the Medik8 C tetra cream have really improved the overall hydration of my skin.
  80. Lightweight hydration

    Erin

    Have just purchased my second bottle of this product. I have very dry skin, especially after my micro+LED appointments, and this serum fixes right up. I love how quickly it absorbs into the skin and I feel like it helps all my other products absorb quickly too, making my skincare routine much faster. Makes my skin feel silky smooth, I will definitely be continuing with this product in my routine.
  81. Worth it!

    Nadine

    I got this beautiful serum as part of a free gift with purchase. A little of this product goes a long way. You apply only 6 drops to your entire face and BAM! Extreme hydration for my very dry skin, it leaves you with a subtle feeling and works best when used at night before bed time, for the ultimate beauty sleep. It is quite pricey for the full size, but go on spoil yourselves! It's very luxurio...

    My skin, although combination is quite dry. This is an absolute must have. It conceals fine lines with its hydrating properties and my skin literally drinks this stuff up. A beautiful product

    This is a great product which I have consistently re purchased. I have combination skin with the odd breakout and this sits so well on the skin under makeup.

I bought the B5 from The Ordinary recently and immediately regretted it, when compared to Medik8 t...

  93. Hydration station

    Nicola

    I love the way this feels on your skin. You’d think because it’s gloopy coming out of the bottle it’d stay like that on your skin but no! It gives you ample time to apply to your face before drying. I love it, gives the skin a nice glow. I use it every morning.
  94. Serum

    Mel

    I got the 10ml as a gift with purchase and it’s good but not something I’m rushing out to buy. It’s very similar to The Ordinary serums only this one doesn’t leave a sticky feeling and hydrates pretty well as a base
  95. Best hydrating serum

    Becky

    Initially, I received a 10ml bottle of this as a tester with one of my Adore Beauty orders... at the time I was using the Hylamide Sub-Q Anti Age serum which I found quite heavy (it does have a number of additional ingredients in it, which would definitely be suitable for someone with more mature skin than I) so I started swapping Medik8 into my morning routine and the Hylamide one to night time. ...

  96. Expensive but indispensable

    Remy

    If you're on the fence about this one just try it and keep your routine up. Your skin will thank you.
    I was confused about how this could be moisturizing as it's a gel.
    I don't know how it works, I just know it works.
    My skin is plumper, my texture is smoother and skin has a nice glow about it.
    This has cemented itself in my pm routine. I love it.
  97. Love it

    Laura

    This is so helpful for rehydrating the skin, especially as I have dry skin! It also provides long-lasting hydration. I received this as a free sample and am looking forward to purchasing the full size!
  98. nice product
