Good, but not sure if I will switch!
Sampled

I love Kiel's products and this is no exception, but I am loyal to my Caudalie S.O.S. serum and I'm not ready to make the switch.

Perfect for that quick lift on the go. I absolutely love it. Thanks Birchbox! I would order this again.

Doesn't provide visible results
Sampled

I'm 30 and for the past two years, face & eye moisturizing has become a part of my nightly routine. This serum felt quite nice, but I really couldn't tell any difference. Smooths? Not noticeably (and I have a 3x magnifying mirror). Brightens? Possibly. Again - really couldn't tell. Worth it? Meh - I'd say no.

Real results

I used this product every night and saw a real difference in my skin! It looked smoother, and definitely brighter. Worth the $$$$!

Love Kiehl's Products
Sampled

I love Kiehl's products. Many of them fall in to the "cant live without" category. This isn't oe of them. Maybe I don't have enough lines yet? But even trying to prevent them and using this sample until it was gone - I saw no real change.

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.

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.
