Most Helpful Positive

Better than HA + B5

Amy H

I prefer this one over the best seller HA+B5.
This one belongs to water-team serum, its texture is really watery while HA+B5 is gel texture.

It absorbs much faster and deeper into my skin than the other, no greesy at all and I feel my skin more plumbed and glowy straight after.
Easy to layer with other products in my routine.
Very good value at this price.

Not hydrate enough if use alone, better to follow by moisturiser
Super watery texture, you need to apply slowly and really quick. Otherwise, it can run over to the neck. (Happened to me sometime).
Because of its texture, I finish the bottle real fast, a month and a half (i used twice a day).

Hydrating but not amazing


I was super excited to try this as it has great reviews! It does provide some hydration but for my skin is not the best serum I have tried from the ordinary.

  2. Great serum!


    It’s a light and watery serum that I find hydrating enough. It certainly seems to help protect my moisture barrier as I’m using several different actives these days. I’d recommend giving it a go.
  3. Helps with pigmentation!


    verified purchaser
    I’ve used it a handful of times and it has already reduced the redness in my face, I have very dry and sensitive skin but this worked a charm! I haven’t been using it long enough to give it 5 stars but highly recommend!

  5. you need this


    this is such a great product—like any good maintenance strategy, you know it's working when you don't notice much. I have used so many TO products and they are honestly hit and miss, but this is perfect for protecting your skin from a high-potency and/or multi-active regime. I love to layer or mix this with Marine Hyaluronics (another A+ must have, every day) + LAA 100% powder (AM only)...the wate...

  6. Quite a watery consistency


    I didn't expect it to be so light and watery. It does hydrate and sink into the skin but I dont think I would purchase it again.
  7. Best Moisturizer


    This is such a good replacement for a moisturiser if you have oily skin/problems with clogged pores. Super moisturising but very light.
  8. Comfortable consistency!


    A watery consistency and no strong smells, my mum uses it for hydration and I have one to help with a bit of redness. Overall, comfortable and easy application!
  9. Good likes a toner


    I thought it was a serum but actually the texture is more likely a toner, watery. without any smells.
    Compared with HA+B5, I perfer this product more, no thicky, watery. You can use it before makeup without worry about the finish and a fighter of primer.
  10. Good


    verified purchaser
    I have noticed a dramatic change with this product alone - but it has a nice texture and is good value for money.
  11. Good hydration support


    I started using this as a lighter alternative to TO's HA+B5. It's lighter, easier to apply and doesn't get sticky. Also found my skin seemed to absorb this (combined with the marine hyaluronics) better than the HA+B5. Helps a little with redness/rosacea too.
    Will repurchase, wish there was a big bottle of this. :)
  12. Good hydration boost


    My skin starts to get dry as soon as the weather gets cooler and often switching to a more intense moisturiser is not enough to fend off the dry patches. Decided to add this serum to my routine this year and it has definitely helped restore moisture to my skin. I would say it needs to be used in conjunction with other products for full effectiveness though.
  13. Extra hydration


    I have been using this products for quite some time and on my 3rd bottle now. Love this stuff for extra hydration with my mature skin.
  14. So far so good


    So far, I like it alot. It's consistency is like water, but a little goes a long way. Easy to apply, tingles a little bit. However it wasnt too strong. It does a good job of making my skin feel tighter and plump but still hydrated.

    One of my fave TO products.
  15. Good moisturiser


    I've used this for a few months and it dose a good job providing basic moisturising properties to the skin.
  16. Good additional hydrator


    Use this Amino Acids in conjunction with Marine Hyaluronics from the Ordinary for some nice light hydration to start the day. Gentle on the skin.
  17. For dry skin


    Bought this for my mum and she has super dry skin. Nothing else works for her, but this one she swears by. She is on her 5th bottle already.
  18. Skin quenching!


    I gave this a try as a way to pump more moisture into my skin. Heavy moisturisers tend to make me break out and I find using this as a toner after cleansing pushes moisture deep into my skin cells. Very light and hydrating.
  19. The Ordinary Amino Acids + B5 30ml


    All round great part of any woman or mans anti ageing routine. This is so luxurious on your skin and so full of goodness... it is an actual buffet for the skin. Always feels amazing after I have used it.
  20. Isn’t a flashy product by any means, but it has the ingredients.

    Rachael McLean

    The Ordinary’s Amino Acids + B5 isn’t a flashy product by any means, but it has the ingredients and the packaging to make good on all it claims.

    Housed in a dark brown, UV-protected bottle, this fragrance-free serum is dispensed via dropper. Although it’s not oil-based, the initial texture is that of a lightweight oil (the second ingredient, propanediol, can cause this feeling), thoug...

  21. Very lightweight


    Very lightweight and absorbs well. My combination skin gets slightly shiny after applying this serum so I prefer using it at night. Does the job for price.
  22. Love it!!


    This is a great serum for all ‘round skin health. Layers well and sinks into the skin beautifully, and is compatible with any other serum/product you’re using (unlike niacinamide, peptides etc). I was hoping for increased hydration but it’s difficult to comment on that because I also use hyarulonic acid, NMF and Cereve moisturiser already.
    The great thing though is something I didn’t expect-...

  23. Amazing


    This makes my skin feel plump and hasn't made my skin sensitive and has been helping my skin barrier
  24. Great product


    Does it's job for a great price. Feels nice to put on and hydrates well
  25. Good moisturiser


    I have found this to be a good moisturiser without causing any irritation to my skin.
  26. Great


    Bought this for my mum and she loves it. She has very very dry skin. Have finished a bottle and wants another already.
  27. I love this!


    I’ve only been using this for five days and my skin looks absolutely amazing! Best thing though is using it for the first time overnight then waking up to smooth and plump skin! Didn’t expect any results overnight at all so was very much pleasantly surprised. I used it in conjunction with Hyaluronic 2% and natural moisturising factor. I put this over the eczematous patch on my skin and it didn’t s...

  28. Love it!!


    This serum is lightweight and moisturizing. I got this to add to my moisturizer cream for added nutrients for my skin. This product is amazing and inexpensive to add to your skincare routine.
  29. Better than buffet?


    I switch between this and Buffet and I’ve noticed it absorbs a lot better than buffet. I can’t tell any other difference between them so I’ll continue to use up my buffet bottle but will probably replace completely with the amino acids in the future.
  30. Hydration support


    I don’t quite realize how much I love this product until I run out. It really does assist with hydration and giving that extra glow to my aging skin. Applies easily and not too tacky or sticky. I then apply an occlusive moisturiser afterwards to lock in the goodness.
    I can’t be without this one.
  31. Hydration support


    I don’t quite realize how much I love this product until I run out. It promotes hydration and gives me a super glow to my aging skin. Be assured it does work. It is easy to apply not sticky/tacky on the skin. I then lock in that goodness with an occlusive moisturiser.
    I cannot be without this one.
  32. It's a yes from me.


    I have really dry skin, and this has been amazing for me. It's taken me a while to figure out exactly what works well for my skin and this is one of my staple products. I use this after the Marine Hyaluronic Acid, and use the Plant-Derived Squalane shortly after that both morning and night.
  33. Hydration staple


    I use this occasionally in my routine when I’m feeling extra dry during winter. Works every time to get y skin back on track!
  34. Very hydrating but made me shiny


    I was looking to change up my Ordinary skincare routine a bit, and after reading reviews that this was better than Buffet I decided to give it a go. It is definitely very hydrating but I've found it makes me a little shiny as (thanks to other Ordinary products!) my skin is no longer that dry, so I'll probably wear it overnight only and stick to Buffet for during the day. Definitely recommend for a...

  35. Hydration Lifesaver!!


    I usually only feel more dry across my forehead with quite an oily T-zone and this product has saved my skin during winter. I no longer feel dryness or tightness across my forehead, and it doesn't make the rest of my face feel more oily. Feels like it gives the skin a drink of water. Would recommend
  36. Hydrates and absorbs well


    The product is hydrating and nicely smooths out the skin. It is quite a lot thinner than all the other The Ordinary serums; this means it absorbs nicely (much better than the Buffet or Niacinamide) but you also use more of it to cover your face.
  37. Amazing value


    I have to agree with the other review about this being better than the buffet, and for the price you can’t go wrong! Definitely something that I will be repurchasing
  38. Will definitely repurchase

    I’ve been using this twice a day after cleansing and before moisturising and have found that it’s significantly decreased the dry and flaky patches I’ve been experiencing.
    I have combination skin (oily t-zone, dry patches) and occasional eczema flare ups on my face and this product has been gentle and moisturising without triggering any breakouts or exacerbating my eczema.
    (For refer...

  39. Nice product


    I have just started using this product and it definitely hydrates my skin. I will continue to use it as my skin is very dry and this product is so accessible and a great price.
  40. So hydrating


    It does hydrate skin so much. It feels so pumped after 1 use. I found this to be better than the buffet on the ordinary. Love the price too. Will repeat this.
  41. I’m glowing

    Angela Kay

    My face is glowing after introducing this to my skin care routine
  42. Great for moisturizing and repairing


    I have normal to dry skin and had a bad break out from introducing a new serum into my routine. I discontinued the serum but my usual routine was not clearing the break out for 3 weeks.

    I started using this serum to provide more moisture and help repair my skin. In a matter of days my skin calmed down and started repairing. I use this serum now every night accompanied by their Natura...

  43. Definitely worth the money


    I really like the consistency - its on the thinner side and my face seems to be glowing a little more after adding this serum to my everyday routine.
  44. Love it


    I have dry skin. Been using this everyday morning and night. Up to my second bottle now. Really enhances the moisture barrier and support. Will return for more
  45. Subtle hydration


    This has subtly increased my skin's elasticity, made it feel slightly more hydrated and smoothed out texture a little. It's not an overt miracle worker, but it does something.
  46. great subtle effects


    I have been using this for around 2 weeks now and have noticed my skin looks clearer, smoother, and has a better texture. The changes to my skin happened gradually and slower than I expected but in saying that, I am really happy with the product.
  47. Works really well


    I love the ordinary. This makes my skin more even, smooth, toned, and soft! An amazing product for the price and lasted a fair while considering the size of the bottle!
  48. Great


    Amazing for oily skin
    It's the second time I'm buying this product, I love it.
    It really hydrates the skin without making it greasier (I have very oily skin).
    I used it every night before I go to bed and my skin feels amazing the morning after!
  49. Love this product


    It protects, it plumps, it hydrates...Love this product.
  50. Average,


    I used the whole bottle and didn’t really notice much difference in my skin condition overall. I’d recommend trying other products from The Ordinary, because they do have a wonderful range. This was just not that great to rave about. Didn’t break me out, but didn’t make my face radiant either. Meh.
  51. lovely product


    I found this product goes really nice on my skin, early days using it but very happy so far
  52. A great addition to my skincare routine


    I bought a whole bunch of TO products and using them all in conjunction makes my skin feel and look amazing! I only need a tiny bit of this product, a few drops is enough for my entire face. It can feel a bit greasy if you use too much but it doesn't take long to absorb.
  53. Soft skin!!


    After a few days I definitely noticed waking up to a smoother complexion, it’s not so heavy on the skin however it feels a tiny bit greasy but overall would recommend, especially for dry skin! I wear it under my primer as well and find it keeps skin well hydrated!
  54. Amazing hydrator


    Very soothing, not scented and feels amazing on my skin. Love the consistency, it is very water like, dries immediately and not sticky at all. I add 2 drops to my face AM and PM. Mixes well with all my serums. Highly recommend this!!
  55. Amazing stuff


    This is amazingly and a must have if you have dry peeling skin like me!!! Such a lifesaver at an amazing price too
  56. affordable and great!


    like it a lot.I mix it with my natural moisturizing factors and my skin feels really hydrated.I had no stinging when I applied it.I will repurchase!
  57. Must have for dry skin!


    The moment I applied this to my face, I knew this would work well for my skin. Within moments after applying this product and letting it absorb, my skin felt so supple and smooth similar to the feeling you get after using a face mask without the sticky feeling. To be honest, when I first read the product description I felt a little worried since it mentioned that the product might cause a little t...

  58. Nice


    Super hydrating to my very dry skin and gentle on my sensitive skin. Its very watery just wish it was a little bit thicker.
  59. Amazingly Beautiful Serum


    A wonderfully hydrating water-based serum that makes my skin feel SO good - for the price it's amazing! I have very dry skin and this has made my skin so smooth and luscious. I would repurchase a million times over! I do agree that using a hydrating toner and moisturiser with it is key, but besides that it's really just a super nice addition to a skincare routine.
  60. Superstar!


    Beautiful, gentle product that leaves skin hydrated, clear and bright. I'm definitely adding it to my holy grail list.

    TIP: Layer with a hydrating toner and moisturiser. Game changer!
