Rated 5 out of 5 by from The best vitamin C The best vitamin C serum I've ever used! The serum has a creamy, very pleasant texture which gives a velvety finish when applied to the skin. After just 2 weeks of use, my skin gained a prettier, more even colour and was much better moisturized. After longer use (about 1.5 months), I can see an improvement in the quality and density of the skin. I love it!

Rated 4 out of 5 by from Came broken I love this product so much. 4 stars because the pump on mine came broken and doesn’t pump out product. I have to open the cap to get serum out which sucks because I feel like I go through it much faster since I don’t have a pump to guide how much I’m distributing.

Rated 3 out of 5 by from I am using this I am using this purely to reduce forehead wrinkles. If feels nice and silky and warm when I apply it, which I like. I think it’s reducing my “eleven” lines, but since I can’t tell for sure... 3 stars. For the price I feel like I should be sure.

Rated 5 out of 5 by from Amazing This is one of the best skin care products I have purchased. I purchased this as part of a gift set with the midnight oil and I can immediately notice a difference in my skin. I use the midnight oil and this, followed by a moisturizer every night and my skin has never looked better. I can’t recommend this enough. My skin is sensitive and never had any issues with this product.

Rated 3 out of 5 by from It’s really hard to It’s really hard to tell if it works, or it may take a long time to see results. The texture is smooth and feels nice on the skin. Since it’s a concentrate, a little goes a long way. It’s lightly scented but nothing overpowering .[product:kiehl’s-powerful-strength-vitamin-c-serum]

Rated 3 out of 5 by from I received a sample I received a sample of this product with a sephora order. I've been trying a few different vitamin C products out to see what I might add to my morning routine. Overall I like this product. I didn't need a lot of it to get full coverage. It did have a little bit of a texture to it but it didn't seem to affect the application of my makeup or other moisturisers. It also does have a little bit of a scent which to me feels sort of medicinal. It's not that noticeable though. The full size product is pretty cost prohibitive to me. Also, it's not a cruelty free and vegan company. Due to the cost and not being vegan, I would probably not purchase this again.

Rated 5 out of 5 by from This is the vitamin C i use every single morning, it is a strong vitamin C so sensitive skin beware. I love that it is in like a cream form versus liquid, I've found that my skin does well with this formula. I have 100% have seen a difference in my skin too, it is brighter and more even skin tone. Also because it is a higher vitmain c, it is doing it's job protecting my skin throughout the day very well. I've gotten to the point where I don't need any concealer when I use this. It melts into my skin and I take a small amount and put it under my eyes as well to help brighten them. This is always in my bag, get it now.

Rated 4 out of 5 by from Dropped one star because of price, but otherwise, this stuff is wonderful. It leaves skin feeling very soft, and can be layered easily with other products.

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