Kiehl's Powerful-Strength Line-Reducing Concentrate - 1.7 oz. Customer Reviews

I feel the sample size is a little small, hard to know if it’s working. I do like the way it goes on feels very nice.

I just used it, ad so far it seems ok. I havent had an allergic reaction of any type and I have SUPER sensetive skin. Excited to see what all this product can do.

I'm a fan of the Kiehl's product line, but this item in particular didn't do anything. My face broke out after using it, so I stopped using it as part of my daily skin routine.

I love how this product feels. It's so silky and smooth. It reminds me of Arbonne's & Smashbox's primer. It probably could even work as a primer. The product is a little thick, so a little sure does goes a long way. I have not notice any changes in any wrinkles or fine lines, but it could be that I don't have any. I do love how it feels on my skin and would definately purchase it to use for prevention.

I think my sample of this was too small to see any major results, but I do love the product and think it would be effective if I were to buy the full size and use it for a longer period of time. The product was exactly what you would expect from Kiehls...a great product. If I wasn't on a tight budget, I would definitely purchase!

From what I've seen so far while using this product on the fine lines around my eyes and mouth, I would be interested in trying out the full size. I have seen a bit of a difference and would like to see the full effect.

As an overall primer this was great. When it came to reducing lines and wrinkles I think I would need a slightly bigger sample and a longer use time to judge correctly. It went on smoothly did not smell bad and I think it did help with the overall look of my skin.

I think this product may have the potential to be good but the sample is too small. It goes on smooth and didn't make my skin oily as others have said, which is weird because I have oily skin.

i liked how it felt when i put it on. it felt pretty food on my face but as i wore it it almost felt a bit heavy. it seems to have evened out my face some. but it's kind of hard to tell what it capable of with just a sample size.

I used this product once daily (morning) and I didn't really think it was doing anything. However, after a couple of days my husband asked me what I got in the new birchbox that was making look younger! My husband doesn't usually notice anything and he definitely noticed it. My sister, who I see weekly, also asked me if I was using different make-up because I looked younger. So clearly it works!
