It's okay

Maybe it's because I'm still pretty young, but I don't notice much of a difference with this one. It exfoliates a little bit, but don't brighten or change my skin much in any other way.

Like but don't love

I really enjoyed trying this product versus having to go out and buy it first. It is a good but not great product. I like the texture and the initial look of it, but as the day wears on, it doesn't last. I actually felt like there was the appearance of build up in my forehead lines versus smoothing.

It's ok...

I have been trying out different serums lately and went through my stash of samples. I do like the smoothness when this product is applied. I don't however notice that it is brightening or toning my skin.

Consistency matters

This product worked well in reducing my forehead wrinkles. However, I noticed that if I stopped using it a couple days they would show again. When used on a daily basis, it does a good job of reducing the appearance of fine lines.

Will work for some

I'm always happy to get a sample of Kiehl's products and it appeared to address some of my beauty needs. It looked and felt lovely and smooth on ,silicone smooth, however it left me with a face full of clogged pores.

I don't have oily skin so it didn't turn into a full-blown blackhead situation but I won't take another chance on this product.

FAN OF BRAND

I am a huge fan of this particular brand of product. I have been using my sample since I got it. I love the feel of this product, and I love the way it makes my skin feel after it has been applied to my problem areas. I have not noticed any dramatic changes, but I'm sure with a line reducing product that change will be gradual. I would recommend this to pretty much anyone even thought it is pricy their name alone has proven to produce such quality products!

Doesn't Absorb Well into Skin

I do not really have wrinkles yet, but thought this could be a good preventive measure. It goes on smoothly, but it didn't really absorb into my skin which made it run into my eyes and irritate them.

Ok product

Went on smooth and worked as a nice primer for foundation. Too pricey for what it does. Cheaper products work just as good.

Hard to notice much difference

I really didn't notice a lot of change from this - I don't have many wrinkles right now so that might be why

Sampled

I used this product for a few weeks and don't really notice a difference. However, I do not have many wrinkles. I plan to continue this treatment until I finish the sample, so maybe my opinion will change.
