Rated 5 out of 5 by from I’m almost 47?? You can’t tell My skin looks amazing. It’s not sagging. Sure we all have the barely noticeable wrinkles when we make that ‘huh’ face but I have noticed my skin for the past two years looking so good. I have not done any procedures or fillers and I am told I don’t look my age. This is the best purchase my best friend who worked for kiehls sold me and I’ve been using it since. It’s a try to believe products bcz it is a little prices and be patient!!!

Rated 5 out of 5 by from I live by this I live by this vitamin C serum. I feel like I simply can't live without it anymore. It evens out my complexion and smells divine. I've never used a vitamin C product that I love more than this. I've used it for about five years and have never looked back.

Rated 5 out of 5 by from Turned a skeptic into a believer Wow! Where has this been all my life?!? My skin’s overall complexion has improved in less than a week! Even my makeup looks so much better ( clean canvas). It feels so beautiful on your skin, like it’s doing its job. My new staple! I’m obsessed. Game changer

Rated 2 out of 5 by from 1 big disadvantage That would have been a decent product if the formulation wouldn’t contain essential oils. Additionally, if the percentage of Ascorbic Acid (pure Vitamin C) would have been 20% or 15%, that would have been also very beneficial.

Rated 5 out of 5 by from I love Kiehl’s and I love Kiehl’s and this product is no exception. I received this as a sample with an Ulta purchase and I am so happy I did!! A little definitely goes a long way and has great ingredients which reduce fine lines. Just after a few uses I’ve noticed my skin to be more radiant with positive differences in texture too. Definitely buying the full size.

Rated 5 out of 5 by from I received a sample I received a sample size (0.17 fl.oz.) from Ulta and I am looking into buying this product. After using for a month, I have noticed a visible reduction of fine lines around my eyes. It is also fragrance free and gentle on my breakout prone skin. A bit on the pricey side but a little goes a long way.

Rated 5 out of 5 by from best daily face serum I've used this nightly for the past 8 years and think it's the best on the market for maintaining younger skin. I am 67 and live in Arizona. My only wish was a better container to use as the pump does not get all product out and would prefer a toothpaste tube style container.
