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.

Hard to tell with a small sample
Sampled

Honestly, I bet this stuff works great. I just was unable to tell with the short amount of time I was able to use it. I am not willing, at this time, to pay the expensive amount of money to buy a full bottle if im not even sure it works. It is a little greasy...

Not very impressed with the sample. It was too small of a sample to truly get an impression of the product. I did not like the texture on my skin, and the smell of it leaves a lot to be desired (which I wouldn't mind if it worked well).

This is probably a product that you would need to use for a while before seeing results, but I didn't like how it made my sensitive skin sting.
