Rated 5 out of 5 by from Vitamin C serum This is my first time using any serum but I did my research and purchased this because of all the benefits it has for my skin and because the price point is better. I’m glad I did! I’ve been using this twice a day for about a week now and I can already see a difference in the overall appearance, my skin looks and feels hydrated and looks plumper! Hopefully it’ll help with some fine lines within the next week or two

Rated 5 out of 5 by from It really works! I don't often write reviews, but felt compelled to write this one after using the Kiehl's Vitamin C Serum for 6 months. I have seen serious improvements in the fine lines on my forehead and the vertical lines in between my eye brows. Honestly, it smoothed out the ones between my eyebrows and for that reason I am hooked! It really worked for me so if you are on the fence I would recommend giving it a try. The bottle lasts pretty long. I use one pump of serum nightly and the bottle has lasted me more than 6 m already.

Rated 5 out of 5 by from 2 for one! This product is a must have in your skincare routine! I initially purchased the smallest bottle to try, then I upgraded to the larger size when I was out. I have never found a product with such a high percentage of vitamin C, plus this formula includes hydraulic acid to seal in moisture so you're really getting 2 products in one! Your skin feels amazing right after you put on and really boosts brightness.

Rated 4 out of 5 by from Amazing! I purchased this two years ago while on a work trip. There was a Kiehls store nearby and so I made a stop to see about purchasing this product I read so much about. I hated it! It didn’t seem to be working for me so I ended up giving it away to my mother when she came to visit. Fast forward to today, I’m quarantined at my parents house, misplaced another serum I was using to fade dark marks and decided to retry this serum which was just sitting in my parents bathroom vanity. Y’all, it’s amazing! It fades the dark marks I get on my chin so quickly! Nothing else has been able to do that. Anyway, I find the whole thing funny and just wanted to let everyone know about my results even though for whatever reason it didn’t seem to work in the past. Great product.

Rated 1 out of 5 by from Do NOT BUY ONLINE I bought the large size of this product this last May for a Mother’s Day sale and I am STILL waiting. I’ve called multiple times for them to send out the product. I’ve been patient a cool about it. Every person said they would send it out, they said it was in stock but then nothing would happen, no emails, no tracking numbers, no call backs. BUT IN STORES ONLY. Which is soooo sad because we’re in a pandemic, buying online should be reliable. Especially from a company like Kiehls their online service is COMPLETELY unreliable. It was my first online purchase with Kiehls and I will never do it again. This product is way too expensive to not get the product you want, especially when you buy the BIG size like I did.

Rated 1 out of 5 by from Thick and Goopy I always use a serum and was anxious to use this one based on what it is purports to do. When I think of a serum I think of a luxurious feeling oil or liquid that goes on smoothly and penetrates my skin feeling deeply moisturizing and comforting. This is none of those things. It is a very thick, goopy cream that doesn't feel at all moisturizing and doesn't seem to soak in. It is also so thick that I have to drag it across my skin which is not the least bit luxurious or comforting. I don't ever find that any skin products make that much difference in the inevitable aging of my skin, so I want what I use to at least feel good. I don't find that anything about this product feels good on my skin. I wish they would change the formula so this serum goes on smoothly and soaks into the skin.
