Love this concentrate!

I used this concentrate before bed until my sample ran out and I definitely noticed a difference in fine lines and the smoothness of my skin. I wish the sample was bigger! Perhaps I should consider purchasing...

it works
Sampled

as I get older I have sleep lines in the morning (okay, they are wrinkles that are getting worse), this helped diminish the appearance of those "lines", so it gets 5 stars from me.

Seemed to help!

This was the first Kiehls product I had tried and I can see why the brand has such a loyal following. After about a week, I did have improvement in the lines on my forehead.

Love this product!

I just turned 40 and all of a sudden am super conscious about all the little lines and wrinkles I am getting under my eyes! I was so excited to get this sample in my box and after making the sample stretch as LONG as I could, I am going to have to break down and order some! It is a little on the expensive side but I was really pleased with the results from the sample and felt like the little lines disappeared. I really love Kiehl's brand (which I had never used prior to joining Birchbox).
