Powerful-Strength Vitamin C Serum for Glow & Fine Lines

I've looked at the reviews for this product and I think somehow there are reviews for different product(s) mixed in here. Also, there is no way on earth this serum could be described as rough or gritty. This is my go to and I can't live without it. Other worldly smooth and absorbs deep into my skin. Leave me with a glow and it is fantastic under makeup, although I don't feel like I really need much on my face with this serum working its magic. Definitely reduces lines and I should know - I am 62. I see a huge improvement in the health of my skin. I hope Kiehl's never modifies or discontinues this product, I would be lost.

I liked the texture of this serum at first and that it feels so cream based. However it stings on my sensitive skin and broke me out within a few days.

So I’ve been using this daily (in the AM) for about 3 months now and I absolutely LOVE this stuff. I’ve noticed a huge difference in my skin - brighter, fine lines have diminished and overall just a boost in my complexion. I pair it with the matching eye cream and VOILA. Best skin ever.

This smells DISGUSTING. Like a rusty nail, metallic. As others have mentioned it has a silicon base, so it feels very smooth, but just sits on top of your skin.

I just purchased my second bottle and I love it. It's very hydrating and I notice a difference if I skip it. I do have sensitive skin and am prone to acne, but I never experienced any irritation or outbreaks like others have. I also don't feel the smell is that strong? All I can say is, if you're on the fence and have the opportunity to grab a sample give it a try. If you aren't one of those who find it irritating, it's likely going to be life cha going for you.

My mother recently said my skin has never looked better, and I attribute that in large part to this product. I've been using it for about 2 years, twice a day.

I like what is does to my skin - it makes it glow. However I wonder if the glow (blush) is due to irritation. I’m okay with the heat feeling but it also feels like sandpaper when I apply it to my face. It doesn’t feel that way on mu hand so i figure my face is too sensitive for it. However I really don’t have sensitive skin

Using it for years. Replenished for the fourth time now. It makes a big difference. Stopped using it for a few months and just started again. Face is glowing and complexion is just much better. One of the few staples I carry

I have light skin and this did nothing but turn my skin orange. I was not wearing any makeup at all and my husband said I looked tan. I wiped my face with a makeup cloth and you can see the orange/pink streaks from this lotion in the photo.

Bought this from the suggestion of a Sephora employee and I have to say I'm disappointed. It has a sort of rough texture and every morning I put it on it kind of feels bad for a second. I also like myvitamin c serum to be less creamy and more like a serum. So I won't be purchasing this again
