Love Kiehl's
Sampled

Love all Kiehl's products!
Used it before I put on my tinted moisturizer every morning! A great product to use day or night.

Very Nice Product

I was very happy with this sample. The texture of this product is really nice and silky. I used it once or twice a day under my moisturizer and noticed a difference in my wrinkles.

slow but works

slow process but shows improvement with time. Does not smell good. Not very impressed compared to other things I have used.

Great results, but a bit greasy

I really liked the results of smoothing out the fine lines but the product was too greasy for me to use in the morning, when I am in a rush to apply my makeup. I would use it in the evening but I tend to use a firming product in the evening.

Really a Line-reducer

I really like this product. The texture is great and it makes a good primer for makeup. It does help to reduce the appearance of lines too.

Nice

I like this product for smoothing out fine lines. I use the sample but it is expensive, will probably not buy the full size.

Love this!

I use this product on my forehead lines - deepest on my face. It does a really nice job of moisturizing and minimizing without being to heavy for my very sensitive skin. Finally something that is potent but doesn't tingle or make me break out!

Great for forehead furrows!

this really made a difference in my deep forehead lines (I guess I look surprised a lot, or so my wrinkles tell me).

Great

I've used this product in the past and forgot how much I like it. It does a great job of smoothing skin. Has a warming feel when applied. It absorbs into the skin quite nicely.
