Miracle serum!
Sampled

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.

Amazing

So far this is my favorite product! The tiny tube sample lasted me almost 2 weeks. I believe it works great.

Seems good so far, but lines still there
Sampled

I can't say I have seen an overall reduction in the lines I see in the morning, but I use this every day on my forehead lines and somehow it feels like it's doing a good job (I know... how do I know that? No idea).

It goes on incredibly smoothly and works well under make up. I use this on problem lines before applying my usual moisturizer - I'm intrigued as to whether this will have a lasting effect!

I am excited about this product and will consider purchasing. Given daily use I can see where I could see a difference in fine lines.

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! :(
Sampled

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.
