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.

Good for dehydrated skin
I love using this when my skin is dry and dehydrated. It helps bring it back to life quickly. However I find that it clogs my pores if used twice a day. I think this is because the product is thick and gel like.

Love
I recently bought this for myself, loved it so much I purchased this time for my daughter in law who also loves it. I use it on top of my other serums to really lock in the moisture.

Hydrating as heck
I bought this to manage my combination skin better. My cheeks, jaw and neck are so much dryer and dehydrated than my t-zone so I use this to add an extra hydration boost. I also add a little to my foundation for a smoother application. Lovely texture, does the job, five stars from me!

Great alternative to hyaluronic acid
Purchase for my husband who has super sensitive skin as and he absolutely loves it. His psoriasis has not flared up at all using this and he has just asked me to buy it again for him.

Superficial feeling hydration
Moisturising, but v lightweight, but for me it does not feel as though it penetrates deep layers. I often have irritated skin from treating congestion, and this stings when putting on delicate skin (say after a peel), whereas their Transexamic acid did not. Would suggest other HA based serums instead if after hydration.
