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.

Rated 5 out of 5 by from I did a “7 day challenge” sample and saw results! I don’t care how it smells, feels, whatever (all of which is mild anyway), as long as it works! I received a sample from Sephora and used it as instructed - and after 7 days I just bought a bottle for the long-haul. My face is typically sort of rough, and my pores are visible. This stuff made a significant improvement to my skin in just a week. I am excited to see the long-term results, though I would be pleased to just maintain the results it’s already given me.

Rated 5 out of 5 by from Major reduction in forehead wrinkles When I finally started using this consistently (1-2x per day) I saw pretty immediate results. The lines between my eyebrows are almost gone and my forehead lines are majorly diminished. The warning sensation I got when I first used it has gone away but my skin looks great - I'm 35 and it looks like it's taken years off my face. I've just reordered a second bottle.

Rated 1 out of 5 by from Tried for 4 months After trying for months, did not see any results. No brightening. No less wrinkles. I don't see any difference between my before and after. I quit Kiehls products.

Rated 1 out of 5 by from Not a good product I am disappointed by this product. It is sticky consistency that does not easily spread and absorb into the skin. This is inferior to other C serums I've used in the past. I will not purchase again.

This product evens out my skin tone and even cuts the oil. My skin looks great after 2 weeks. —Eric717, kiehls.com
