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

i was alittle scared to try his since i have thin hair

I like using this often is good and it smells great

Lov love this line reducing concentrate! I noticed a huge difference in skin tone and texture within days of using. I've been using this multiple time ps a week sinc I received as sample and love it. Very lightweight and smells good!

I have never tried a serum before & love it! I have also never tried Kiel's products before. They have a new customer for sure!

I am relatively new to wrinkle products, but I used the entire tube and went ahead and bought an actual bottle. I use this morning and night and it makes my skin look smoother and feel softer!

I sampled this and it was awesome. Goes on light, immediately makes your skin look more toned. It did make my eyes burn a little when I layered too much one once, but if you use a thin layer it feels good.
After several days I felt like my fine lines really disappeared. I like that this is a retin-a free product that actually works. Will likely be buying this soon.

Too many skin and hair products month after month! I want more makeup.

You can use this product under your makeup or as a night treatment.

Loved it. Very lightweight and did not effect my sensitive skin. I recommended this to everyone I know.

Not sure I would buy this because I can't see results from the sample but fees nice putting it on.
