Miracle serum!

I am so obsessed with this product after receiving the sample. I just turned 31 and have been seeing wrinkles on my forehead...if I use this serum before applying makeup... it smooths them and makes them pretty much invisible.

I am a big fan of Kiehl's products, I have always had success with using them. This is a product I hadn't tried yet until I received this sample and I love it. Another great product.

Great but not for me! :(

I tried this product for a week with my normal routine. Its an amazing product works well to reduce wrinkles and aging lines, but if your someone with seriously sensitive skin like me. Then you might want to think twice about using it. I have some bad pimples from using this product. But that is just my skin aside from that I really think the product did wonders.

I am now obsessed with this product, bought it immediately !! It is a miracle! Somehow it brought life to my face and was so pretty just by itself without any makeup on top.

big difference

I started using this product as soon as i got it in my box. I noticed a difference immediately. It works very well and i love how smooth it goes on. It acts as a primer for the lines on my forehead. I would highly recommend it.
