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...

Kiehl's Line-Reducing Concentrate

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).

meh

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.

Fell short
Sampled

Love Kiehl's products but this one fell a little short. I used the product once a day in the mornings over a 2 week period but didn't see any changes in my smile lines. The concentrate does improve skin texture.
Will try twice a day and see if that helps.

This product didn't really do anything for me. I don't have too many wrinkles, but didn't notice any difference

line reducer
Sampled

Maybe I too young to worry about lines but I didn't see much difference from this product. This might be a good product for when I am a little older.
