Product Description

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 creates a perfect make-up canvas.


KEY INGREDIENTS:


• 3% polyglutamic acid complex is a natural high molecular weight amino acid polymer, specifically designed to enhance skin moisturization.
• 2% invisaskin maintains moisture levels in the skin.

Directions

Perfect for the AM and PM.

Use as a last step before make-up or follow with a moisturiser if preferred. For long lasting make-up, mix a pea-sized amount in foundation for smooth application.

Rated 4 out of 5 by from Does the Job [This review was collected as part of a promotion.] I contacted INKEY for a recommendation to help keep my skin hydrated in the colder winter months and they suggested this serum. I use it after my hyaluronic serum to seal in moisture and have found it does exactly that.The only reason I gave 4 stars and not 5 is the smell. The smell reminds me of nail varnish remover, it’s not that bad and you get used to it but smells a bit chemically. No scent would be great.

Rated 5 out of 5 by from Perfect mixed into make up [This review was collected as part of a promotion.] I love adding this to my foundation to make it extra moisturising and dewy. Lovely on its own too.

Rated 5 out of 5 by from Packs a Punch! [This review was collected as part of a promotion.] This product is an absolute powerhouse on my 40 something, sensitive and highly reactive eczema prone skin. It really isn’t kidding when it says that it holds in four times the amount of water. It has seriously helped get the moisture back into my skin and I also add it to my foundation and I serum to get an even more glowing and natural finish without any cake in this or any product sitting in fine lines.

Rated 5 out of 5 by from Hydro Barrier Serum [This review was collected as part of a promotion.] Can’t fault this. Love the information Inkey does regarding the necessity of order for their serums. Being old and now needing glasses, I can see the order ‘blobs’ without having to continually having to put on/take off my glasses when putting something on my face - a huge plus. Perfect consistency means it feels like it’s doing exactly what it says
