Once you?re done trying to pronounce it, THE INKEY LIST?s Polyglutamic Acid is the dryness-banishing formula that all dehydrated skin types should add to their #shelfie. Holding four times more moisture than hyaluronic acid (*gasp*), polyglutamic acid is a hydration powerhouse ? and then some. Unlike hyaluronic acid, the magical ingredient has large molecules, allowing it to form a thin film on the skin?s surface to prevent water loss, while plumping the appearance of fine lines and brightening lacklustre or uneven complexions. With a 3% polyglutamic acid complex, THE INKEY LIST?s formula leaves skin smooth, supple and oh-so hydrated ? you can even combine it with their Hyaluronic Acid for a mega dose of moisturising goodness.

  1. Sarah

    The Polyglutamic Acid applies easily, absorbs quickly, and sets to a nice finish. This can fit into any routine very easily. I recommend applying this after other serums but before moisturisers. If you are looking to add some additional hydration into your routine this is a nice and affordable option.

  2. Lauren

    I have dry skin and it gives hydration. It feels just great and the price is good too! Love it!

  3. Sandman

    Was excited to try this but it doesn’t work the same way as hyaluronic acids I’ve used. It’s a very slippy/silky (aka silicone heavy) gel that just feels like a primer to me. No hydration effect whatsoever. It just seems to work by forming a silicone barrier. Just another silicone laden disappointment from this brand for me.

  4. Moogie

    THIS IS INCREDIBLE. I have combination leaning oily skin so am always worried when using products aimed toward drier skin. But this is super hydrating and has possibly the nicest texture I have ever felt. Goes on like velvet and skins into the skin beautifully. Amazing for under makeup, skin had that soft matte look to it, definitely helped with it lasting longer too!
    Cannot recommend this enough, so happy 10/10

  5. Sophs123

    After reading all the great reviews and doing a bit of research I couldn’t wait to try this. My skin feels soft and moisturised and I love the lightweight texture of this serum, I use it once a day and it blends perfectly with my other Inkey List products. Highly recommend!

  6. Lisa

    This is the best hydrating serum I had so far. I didnt expect much from it due to a silicone base, but hyaluronic acid serums don’t work for me and they are very sticky. The vitamin b serums, e.g.: skinceuticals, make my skin much drier. This one hydrates well, doesn’t make my skin greasy and doesn’t break me out. Perfect to use under makeup (thanks to silicone’s). My skin: sensitive, very dehydrated, combination skin. 26 years old.

  7. Kiki

    The product does what it says in terms of basic hydration and it wore well under sunblock and make-up. However, I had hoped that it would keep my skin hydrated for a solid works day wear. I found myself reaching for my hydrating mists nearing the last few hours of my work day to keep the hydration. I would suggest to still wear a hyaluronic essence/ toner under the Polyglutamic Acid for better hydration throughout the day.

  8. JintheUSA

    I don’t understand these products! This and the hepta peptide are sooooo drying. I have mature combo skin and now my skin is parched! Seems like it’s actually pulling all of the moisture from my skin, even after using rosewater before AND after. And it does not work well under makeup. Am I doing something wrong?

  9. Shaun

    I hadn’t heard of Polyglutamic Acid before this, but as a lover of Hyaluronic, I just had to try it! I love the texture – it makes my skin feel instantly smooth! I also noticed that over time, I wasn’t getting flaky skin. All in all, this is great. I layer it over Hyaluronic for extra benefits too.

  10. Fiona

    Very pleased

  11. dizzyblonde51

    I have used the Ordinary Hyaluronic Acid before and did not find this product to be better although it is more expensive. I have mature skin and did not find this a very beneficial serum. I also found the bottle to be only half full and it was soon used up.

  12. Lucia

    I want more hydration and I think this works! Great!

  13. addicted_to_face

    I absolutely love this product! Its one that I can honestly say makes a difference to my skin daily. My skin looks plump and stays hydrated all day when using this. I layer over Hyaluronic acid as advised by The Inkey List. It helps my makeup to stay looking fresh all day too! On my third bottle.

  14. Nicole

    I have dry/dehydrated skin and this is amazing! I use it after cleansing and toning in the morning, under my moisturizer. It adds an extra layer of hydration and preps my skin perfectly for makeup!

  15. Beauty Bee

    I absolutely love it. Ideal product for dry skin. Very smooth and isn’t greasy.

  16. Vivi3

    It replaces my moisturiser in summer. I like its texture, not heavy at all on my combination and sensitive skin.

  17. n

    I never ever leave reviews but this has SAVED my skin!! I have dry-normal / sensitive skin and have issues with eczema too! This has plumped my skin and has completely repaired my moisture barrier / hydrated my skin! So amazing.

  18. TaliaRS

    I love this so much that I had to take it on holiday with me, I use it on top of my serum and under my moistures just like the instructions recommend and it not only feels beautiful but gives my skin such s hydration boost I will definitely be getting more of this when it runs out but that will take a while as you need the smallest amount at a time

  19. Cityskin

    This is what my skin has been craving! Since introducing this in to my routine, my skin is plump, glowing and healthy! I have acne prone skin and I’ve been focusing on repairing and strengthening my skin’s barrier, this goes the extra mile to keep my skin hydrated and happy almost instantly.

  20. Julievar

    I love this acid does really add moisture.

  21. Kathy

    PGA is said to be 10x more moisturising than HA, and I couldn’t agree more on this. I have been really loving this serum cos it just made my skin really smooth and hydrated. Couldn’t recommend this product more.

  22. George

    I will repurchase this again

  23. Anna

    After reading rave reviews about this acid I was quite disappointed – after 2 weeks of daily use it appeared to actually dry my skin out as opposed to retain moisture which it is meant to do. My skin is no different apart from being drier, so not good for me and (yet) another futile purchase.

  24. RM

    I will 100% purchase this again. An awesome product… My skin feels plumped and hydrated. I use this in conjunction with “Oil of Africa” Marula Oil.

  25. MM

    Price per performance 10/10.
    Makes your skin very soft. I mix it with my Clinique moisturizer and it works amazingly

  26. Mercy

    I love it. My face feels so soft and smooth. I will order again.

  27. Sharan

    Never have I gone so long without even the tiniest bit of dry skin!! I’d heard amazing things about hylauronic acid having moisture retaining properties but it didn’t do as much as I’d hoped for on my dry skin…but this stuff?! OH.EM.GEE. it’s frickin incredible!! I’ve just bought another 4! One for each of my daughters, my mum and a spare for me!

  28. Lisa C

    A great product. It locks hydration beautifully into my skin. It’s also so great for the price point!

  29. J

    I had high hopes for this and it left my skin so, so dry. It took a few days and a lot of hydrating cream to fix! I would give it 0 stars if I could 🙁

  30. SR

    Absolutely love using this in combination with squalane oil and Weleda skin food. I use one pump morning and night, after using the oil and before the cream and the combination is gorgeous. My skin is incredibly dry with zero natural oil, cracked and peeling. This has hydrated and smoothed my skin for the first time! The pump is also fantastic! (And of course the price!) recommend!

  31. Hannah

    It just dried my skin out really bad – and the packaging is really cheap.

  32. Amool

    I loved it. Works well with hyaluronic acid serum to maximize the benefits of hydration

  33. Flv

    I’ve used up a few. I love it! I will repurchase for sure, it’s a must!

  34. Bev

    I mix this with NIOD photography fluid opacity serum as the last step in my routine and it leaves my skin looking smooth and glowy, and definitely helps to lock in moisture. It does have silicones in it, but for me, that aids its performance as a primer before I put my foundation or tinkered moisturiser on top. I can not recommend The Inkey List products enough, absolutely brilliant!

  35. Shazza

    It’s… ok. Very thick and I was using more than one pump. Not noticed much difference tbh. I’m going to leave it to use when my skin is having a bad day and not regularly, if you know what I mean.

  36. Sandman

    This is just a pile of silicone. It feels like silicone. It acts like silicone. Polyglutamic Acid is one of the last ingredients in the INCI list and there’s tons of silicones before it.
    When using this, my face has that telltale slippy silicone feel but my skin starts to feel taut and dry throughout the day. I don’t get this with a good Hyaluronic Acid serum.
    I highly doubt the active ingredient in this will do anything amidst all the silicones and in practice, for me, it doesn’t.
    I applaud INKEY for their innovative attempts with new ingredients but I don’t think their formulas support the ingredients they’re using sadly.

  37. Line

    Order this after seeing the reviews but hasn’t met my expectations. Having dry sensitive skin, it doesn’t sit well on my skin. On the positive side it never broke me out or create dry patches,…I just need to find another way to use this product for it to work well for me

  38. Lhmcd1

    It’s true, people are asking me what’s different about me. They ask if I’ve lost weight? I haven’t. They ask me have you have something done to your face. I have to reply and tell them about how wonderfully well this product works. I’m 55 and I do look different. I will order this again and I will be telling as many friends I know how well this works. Don’t miss out. It’s a fabulous way to moisturise your skin as I’ve gone from very dry, tight and painful to healthy.

  39. DBG

    My skin doesn’t like HA’s – they seem to be drying. This product, however, gives you lovely, soft, moist, glowing skin. Love it, and what a great price.

  40. Plastic fantastic

    Don’t get me wrong, this product is bizarre. Quite thick and silicon like – but wow. Incredible hydration with a completely matte finish. I use it after all my other serums and hyaluronic as a last step. It created a truly airbrushed, matte, flawless finish whilst locking in all the goodness and moisture from your other products. Looks fabulous under makeup too – just don’t apply too much. Innovative, extraordinary – inkey list: I salute you

  41. Ren

    I can’t recommend this enough. I have very dry, eczema-prone skin. This has helped to totally transform my dry skin and keep my eczema at bay – my skin has gone from problematic to essentially flawless, with many of my friends noticing the huge change. It works best when you use it before a rich moisturising oil – I use it every morning and night before applying The Ordinary Marula Oil or the Inkey List Rosehip Oil. I’d also credit the transformation to using The Ordinary Retinol 2% twice a week and The Inkey List Lactic Acid to get rid of dry patches when they appear (which is getting rarer and rarer!). Highly recommended as part of your skincare routine!

  42. Poshhippy

    Really lovely product that does hydrate the deeper layers of the skin. Only after a week my skin is plumped, hydrated, smooth and comfortable. Definitely aids in repairing the skin barrier. Would highly recommend.

  43. George

    Very good product. I will repurchase this again.

  44. BBeauB

    I have purchased a few of The Inkey List Products now, but I have to say the Polyglutamic Acid is my absolute favourite. I have noticed my skin appears healthier and one fine line on my face that really annoyed me is definitely less noticeable. I am just about to order my 3rd bottle, it’s a great price too. I love It.

  45. Polly

    I have dry skin so probably need a bit more hydration, but for the great price it does a really good job.

  46. zee

    My skin had been dehydrated for so long, it felt awful and sensitive and was breaking out everywhere. i’ve been using this morning and night (2 pumps) for 4 days and I’ve seen a huge huge improvement in such a short amount of time. My skin looks clearer and brighter and feels softer and plumper. So happy and so excited to see the difference with continued use!!!

  47. Darina

    I don’t like the consistency of this product . As soon as I apply it to my face it dries up. My face doesn’t look or feel any more hydrated/moisturised than usual and the worst is a strong alcohol smell.

  48. hayleilei

    Totally surprised to apply this serum and have it feel like a primer – to then realise that dimethicone is the second ingredient!! Personally I don’t like the texture of silicone and don’t understand its place in this product. It’s nice under makeup, however, but just not what I hoped it would be.

  49. MariaEx75

    I used it pm right after my hyaluronic acid and it is so light and hydrating for my oily skin. For winter, I use another hydrating cream on top of it and on summer I use only hyaluronic and polyglutamic for hydration. I already bought my second bottle. Definitely right for oily skin.

  50. Glam granny

    This works for me. I occasionally use hyaluronic acid for a couple of days to give my skin a change but I prefer the Polyglutamic after ‘The Ordinary’s’ “Buffet” I used to buy high end, really expensive, anti-aging products for my skin. Then I read the labels. Now I get better ingredients and great skin (for my age) but don’t pay for colour, perfume, glam, containers or film star advertising. It’s gotta make sense!!

  51. babymable

    This is a weird product. I don’t like the consistency of this. As soon as I apply it to my face it dries up. I have to try and spread it as soon as it hits my face. I also have to use double the recommended amount it suggests as it’s very drying. My face doesn’t look or feel any more hydrated/moisturized then usual. I won’t be buying this again. It may work for some people but didn’t do anything for me.

  52. Lady_pilot

    Its thick but it did make my skin feel better than before

  53. Soph

    I have dry/ dehydrated skin and usually suffer from patches of eczema on my face. This has honestly changed my skin for the better. I use it straight after The Ordinary Hyaluronic acid to maximise the hydration benefits. It has a very thick consistency, so I’m not sure how good it would be for oily skin, but if you have very dry skin I couldn’t recommend it enough!

  54. Sammi

    I cannot speak highly enough of this product, I struggle with dry skin and also have psoriasis, so have to be careful what products to use on my face. I have been using this acid for approximately 6 weeks, my skin has really improved.

  55. Flv

    This is amazing!!!I never had such an amazing impression after using a serum. So I am using first the Hyaluronic acid from them or The Ordinary or Mixa, then I use more serums from them and The Ordinary(niacinamide, q10, matrixyl, alpha arbutin, acids, retinoids etc, not all together, some in the morning or evening or alternating) and then I apply this at the end. The feeling of this serum is the best and the skin feels so good after. I also apply a moisturiser or oil after this. It has a silicone texture which many people hate (they think it’s bad for the skin when actually any silicone protects the skin forming a barrier and doesn’t let the skin get dehydrated). I am almost done with med school and I want to do dermatology so I am reading a lot about ingredients.I will repurchase forever!

  56. Lyds

    I was suffering from really bad dry, peeling under eyes, as well as the skin over my face, and this completely cleared it up! Your skin will feel replenished within 1-2 days, and now I can confidently wear makeup without worrying about my face peeling.
    I used two pumps morning and night, before my moisturiser and after I had cleansed/serum/acids.
    A MUST HAVE for those with dry skin or looking for extra hydration!!

  57. Suvi

    It does make my skin feel soft, but I haven’t really noticed any effects of hydration that it was supposed to do. Hardly repurchasing again.

  58. Flvv

    I am on my second bottle and I love it! I already have back ups of it and will continue buying even more!!

  59. Collette

    Brilliant product at a great price. It hydrates really well and leaves my skin feeling soft and smooth.

  60. Beck3012

    I absolutely love this product and I’m back to buy another. I used it morning and night and I genuinely see results. My skin is softer and plumper. I use it in conjunction with another brand hyaluronic acid (which I’m not a fan of so will try Inkey List when it’s back in stock!). I like the consistency, it applies really smoothly and isn’t sticky. I love it so much I pulled the lid off to scrape every last bit!

  61. Feelrippedoff

    Hasn’t done a thing for my skin. Bottle barely half full and the recommended pea-sized amount barely covers my cheeks let alone my whole face.
    I wouldn’t mind if the damn thing at least showed at least SOME improvement but alas it doesn’t, just like the majority of products I’ve tried.
