super hydrating feels like nothing on your skin. It's a really affordable plumping serum for me that I miss every time I run out.

Polyglutamic Acid

I bought this because I am 48 years old and sometimes my foundation settles in my fine lines and emphasizes my textture. I mix a bit with my foundation and it helps it to go on more dewy and keeps my skin hydrated throughout the day.

Discovered this in the Advent Calendar and had to buy another one. Prefer this to any Hyaluronic Acid I’ve ever tried. It’s amazing and makes my skin so soft and plump.

Well It's something

I wanted to use with my foundation, because I believed the hype, but my skin is oily, so you can imagine it's not the right product for me, but if you have dry skin you will love it.

Lives up to its hype!

5 stars out of a maximum of 5

Got this in the advent calendar and excited to try as a big fan of hyaluronic acid for hydration, this promises higher levels! Love the texture and no pulling which I’ve found with other brands.  The smell is a little off putting but a great product if you can get past this! Great results, super hydrated skin! Definitely re purchase
