Polyglutamic Acid Serum

\ pol-e-glu-ta-mick \ a-sed \
A powerful hydrator for the skin's surface, Polyglutamic Acid can hold 4x more moisture than Hyaluronic Acid, locking in moisture and helping the skin appear instantly smoother.

This 3% high molecular weight amino polymer is specifically designed to enhance skin moisturization on the surface. This helps to reduce the appearance of fine lines, as well as brighten and even skin tone. The lightweight silky texture of Polyglutamic Acid Serum creates a perfect make-up canvas.

It really does improve hydration

slightly odd smell - not unpleasant, just unusual. from the second or third time I used it - I saw a definite improvement in my skin.

Perfect for under makeup

A perfect primer for people who don’t really wear much makeup. It makes my skin look plump and healthy.

Silky smooth

This serum texture is silky smooth when I rub it on my face. I have been using this from couple of weeks and I love it. I use it along with my hyaluronic acid to boost up the process and gives us a plumped skin .

Saviour for repairing skin barrier!!!

I purchased this from a recommendation from Millie Mac after seeing her ad on TikTok, and I can safely say it has been a game changer in my skincare routine. From the first time I used it, my skin felt so much more hydrated and softer. I’ve been using it every morning & night for the last few months and the bottle last for so long!! My skin has never looked or felt smoother, it took away my forehead texture (& little bumps) and leaves my skin glowing!! It also sits really nicely under makeup, which is a bonus, and my makeup goes on smoothly over the top of it. The Inkey List, you SMASHED it with this product!!
