Great Product

This is the most surprising line-reducing skincare product that I have used. Why? I was able to see a difference just by using a small sample. I am very excited about this product and will definitely purchase.

Love it

I love this stuff! I use around my eyes (crows feet), and also on smile/frown lines. It really softens and moisturizes those areas and fine lines.

I'm a serum junkie, and this is an amazing one. Keihls has nailed it! This just makes fine lines disappear. It evened my skin tone, and left me soft, smooth and moisturized. I wish it was cheaper, but it's worth every penny honestly.

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.

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