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.

Brilliant makeup base!

This stuff is unbelievable as a makeup base. I'm 42 and have combination skin and this completely evens out the surface of my skin prior to applying makeup. I am skin and makeup obsessed and even though this is by far the cheapest product I use, it is one of the best. I've bought multiple times now. Give it a go, even it doesn't work out for you, you are not breaking the bank and can use as a nice hand moisturiser for a few weeks.

Smell is a big zero

I don't know if i got a bad batch but it has a very strong chemical / paint smell. I want to like this product but the smell is a zero star for me.

So smooth

I've got particularly dry skin, so this does help in my routine. But might not be an essential for other people. It makes my skin very smooth, and I love the texture.

the smell

It’s a new product for so far it feels good on the skin but it’s very thick and leaves my skin feelings hydrated but the smell is horrible! i can tell it’s not an added fragrance but it almost smells like wet paint after it’s dried down the smells goes away but for my sensitive skin it’s a no 😫

Please remove sorbitan oleate

This does a great job moisturizing and locking it in. BUT after using for a few weeks my skin is clogged. analyzed the ingredient list and found it has sorbitan oleate (3) moderately comedogenic. Please reformulate!
