Love Kiehl's products, but this was just average
Sampled

I wasn't sold on this. I didn't notice any visible results after using the sample. My skin did feel slightly tight after applying but that wore off shortly after applying. I prefer a serum that is more moisturizing.

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.

This was an alright product. I didn't feel as though the promises made by the description would actually come true.

Great texture, not a miracle worker tho
Sampled

This feels incredibly nice on the skin; feels almost whipped, so light and absorbs quite easy. I received the sample size, and used for just the undereye area where I'm getting fine lines. The sample lasted me about two weeks, which was great. No line reduction was noticed, but I feel that it moisturized this area much better than regular creams.

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.
