Rated 4 out of 5 by from This is a great This is a great serum that shows real results! I was impressed how it evened out my skin and made my skin glow. I personally like the more watery textured serums and this is more like a cream. It didn’t stop me from loving it! [product:kiehl’s-powerful-strength-vitamin-c-serum]

Rated 5 out of 5 by from Reduced the appearance of my pores I know that this is technically for line-reduction, but I've been using it on the enlarged pores on my forehead and it's working. I got this as a sample with a different purchase and even though I don't really have any wrinkles, I didn't want to waste the product. I've been using it on my forehead and I can't say that it has erased the pores, but it definitely made them less noticeable. I stopped using it while on vacation but my pores still look smaller on return. I'll be buying it next time!

Rated 5 out of 5 by from Powerful Vitamin C I started using this product whn my son gifted me a Kiehl’s set for Mother’s day. This Vitamin C cream has a warming sensation when you rub it into your skin. I have definitely seen improvement in my dark spots. I have combination skin.

Rated 5 out of 5 by from Consistent part of nighttime regimen I’ve been a loyal Kiehl’s customer for 20+ years. It wasn’t till I reached my mid 50s that I realized the value or sing Kiehl’s on my skin. As I get older, I see the way my skin needs a little more help and the Powerful-Strength Vitamin C Serum is a must part of my nightly routine. My skin is smooth & radiant each morning and see improvement every day.

Rated 1 out of 5 by from Cheap ingredients The second ingredient is DIMETHICONE, which is a cheap silicone that sits on top of your skin. It creates a barrier, trapping oil in and falsely giving you the impression your wrinkles are less pronounced. Don’t buy this.
