Didn't notice a difference
Sampled

I really didn't notice a difference in my skin. I've used other products that helped better with my fine lines and dry skin

Too small
Sampled

This sample is way too small to be able to tell if it would actually work. Send me a full size bottle and I will let you know how it does over a longer period of time! hahaha

Nice sized sample
Sampled

The formula stayed pretty tacky on the skin. I've tried other skin care trim this brand and they just seem really mild.

Hmm, no difference
Sampled

I am always up for a better skin care product and had high hopes that this would do as it promised. Nope. I followed the directions exactly and saw no difference. It felt sticky on and made my face feel even more dry.

Just ok

The sample was too small to see results. I base my purchases on results.

It does nothing for me

I have been using this product for WEEKS and have not noticed any difference. This may be because my face is well taken care of as it is. Stay out of the sun. I suppose I'm still too young for anti-aging problems.

Not my favorite

I am always looking for a serum to brighten and refresh my skin. I was hoping this would be it...but, sadly no. You can smell the vitamin c in and that is refreshing but the after smell kinda lingers and I can't pin point what it is. The sample was not big enough for me to continue and see results. I don't feel like I can give a 100% accurate review on this for that reason.

It was just ok.

I think a sample like this needs to either be bigger or not at all. there wasn't enough to start seeing a difference. I am sure it would be a good full sized product, as most of Kiehl's is!

Not what I thought it would be.

I recieved this as a sample. I have very fine lines thanks to being a former smoker (though yay, I'm not anymore) - but I'm young yet, but very pale skin (I'm blueish in places, you can see my veins clearly in some spots too, a couple of yellowy-spots comin' in from aging) so I thought okay, this should be nice. It should do something.
Well, for me it didn't. I mean, it was a nice moisturizer, and I didn't see my face get any worse, but I never saw it 'smooth, brighten and tone skin'. I have the same texture, density and pasty-ness as before. It smelled nice though, very light and not noticeable until I intentionally smelled it.
