Really? This is basically a bunch of silicone-based gunk to give the illusion of smoothing the skin, with some Vit C thrown in. Adenosine might be a great ingredient too but not worth putting the chemicals on my face. I get a fully natural C product with many more skin-nourishing ingredients for so much cheaper than the full size of this is being sold for. Also the sample was so tiny that there wasn't nearly enough to assess efficacy even if I had really wanted to.

Smells like metal, didn't see many benefits
Sampled

I only used the trial size from my box, so that may be why I didn't see any benefits. Like many other people, this would come out clearish with spots of white, and I had to reallllly shake up the tube to mix it up so it came out milky like it was supposed to. The product smells metallic to me, which I don't like.

I did not care for this product at all. I was super excited to try something targeted for fine lines and wrinkles but all it did was break me out

This product smells like chemicals. It stings on my face and i'm pretty sure it's not something I will ever use.

Smell disgusting and stings
Sampled

The smell is horrible like rusty metal or something like that. It also makes the skin burn and sting. Nothing good about this product!

smelly!
Sampled

this product didn't really impress me very much and it smells terrible. It made me wonder what kind of chemicals I was putting on my face. I couldn't use it more than twice, it was too stinky.

NOt impressed at all
Sampled

I used the sample sent in my box with no perceivable benefit. I also did not like as a moisturizer. I would consider using this even if I did not see any effect. I dont have many wrinkle yet but I did not even like the feel.

Can't see a difference

I have used Kiehl's products before and like many of them. I didn't see any difference with this small sample.

Dimethicone
Sampled

I don't know what this is, but it is in every makeup primer I use and this cream felt like just that- a layer of makeup primer. It felt like I was coating my skin with grease. Not for me.
