Skin care doesn't have to be confusing. The INKEY List is on a mission to debunk beauty jargon and put the power of knowledge in your hands. Its straight-talking range includes all the industry's best-loved heroes (from retinol to hyaluronic acid) in no-frills formulations that deliver incredible results... And the Polyglutamic Acid Serum (30ml) is a case in point, being an ultra-hydrating formula that quickly absorbs into skin to grant a soft and supple complexion.
Once you're done trying to pronounce it, The INKEY List's Polyglutamic Acid Serum (30ml) is the dryness-banishing formula enveloping complexions in much-needed moisture.
If your skin leans on the dry side, chances are you've tried hyaluronic acid... but what if we told you that there's an ingredient that can hold four times as much moisture? Enter polyglutamic acid, a hydration powerhouse that cleverly forms a film on the skin's surface to prevent water loss. With a wealth of benefits to its name, polyglutamic acid plumps the appearance of fine lines and wrinkles, brightens lacklustre complexions and evens skin tone and texture. Starring 3% of this potent ingredient, simply glide the formula across your skin to reveal an oh-so hydrated complexion (you can even combine it with the Hyaluronic Acid Serum (sold separately) for a mega dose of moisturising goodness.
Aqua (Water), Dimethicone, Butylene Glycol, Bis-PEG-12 Dimethicone, Glycerin, Polymethylsilsesquioxane, Polysilicone-11, Phenoxyethanol, Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Isohexadecane, Propanediol, Coco-Glucoside, Sodium Benzoate, Hydroxyethylcellulose, Polysorbate 80, Ethylhexylglycerin, Potassium Sorbate, Decyl Glucoside, Dimethylacrylamide/Acrylic Acid/Polystyrene Ethyl Methacrylate Copolymer, Sorbitan Oleate, Trisodium Ethylenediamine Disuccinate, Polyglutamic Acid, Caprylyl Glycol, Hexylene Glycol, Oryza Sativa (Rice) Bran Extract.

this is so underrated
for this active ingredient to hold 4x more hydration than hyaluronic acid i don’t get why it’s not raved about more. i use it on damp skin after cleansing and pat it in. it leaves my skin so soft and supple. but the trick is to layer hydrating products as it retains so much moisture. i then use a really good moisturiser but sometimes before, i use a hydrating mist to really get the best effects. since the weather has changed my skin has been so dehydrated no matter how much i drink. this product has truly saved my skin!!

Very hydrating
I find that some hyaluronic acid serums can break me out so this is a great alternative. It combines well with all of my other moisturisers and serums that I have tried and makeup sits on top beautifully too. It really does create the perfect moisturised canvas in the morning. I find that skin stays moisturised throughout the day even in winter and I don't get the dry cracking effect that I am prone to on very cold days when I don't use this. A very affordable but effective serum.

Perfect
Excellent serum. Gives the skin moisture. Highly recommended to anyone who's make-up does not sit well because of dry skin. You can see the results after a week's use.

1 step glass skin
I'm not sure about the long term benefits of this, but immediately after using the results are amazing! I use it just before moisturiser in my routine, although the description for this is that it locks in moisture, I feel like it locks in my serums/treatments as well! It does have a fairly strong chemical/plastic smell, but that fades quickly. I have never had such smooth skin after using anything, this is far better than silicone primers, it leaves my skin bouncy, dewy, and velvety smooth! Definitely going to keep in my routine!

WIP
I haven’t been using this product long enough to speak on the claims of locking moisture in. However, my skin is dry, dull, and sensitive, making it difficult to find products my skin tolerates. This hasn’t broken me out, and it makes my skin feel soft after application. Based on my current thoughts, I would repurchase.
