You’ve aced Skincare 101: You drink plenty of water, log eight hours of sleep a night, and diligently apply (and reapply) SPF. But to get your advanced degree, you’ll want to invest in a targeted antiaging serum like Kiehl's Powerful-Strength Line-Reducing Concentrate. Loaded with vitamin C and other potent ingredients, it smooths, brightens, and tones skin. Get ready for your best skin yet.
I've only been using this a few days, but so far I'm happy with it. I do feel that the lines around my eyes are less noticeable and my skin looks more glowy too.4
It was moisturizing in that it left an grease-like shine to the skin. It didn't produce any outstanding results.3
I like the texture of this product and how it makes me feel. I havent used it long enough to know if it really works but im excited to see if it does. Im 28 and this is my first anti aging/line reducing product.5
This works well as a primer, but isn't particularly moisturizing.1
I liked the product, just not enough to buy the full size. It definitely gets hot when you put it on. I think my face looked smoother in general but couldn't really tell a big difference with wrinkles.3
I haven't had trouble with product like I expected my skin to have. So far my sensitive skin seems to like it. It's only been a couple of days, so time will tell. I love the idea of my fine lines being taken care of ... so I'm hoping.4
I didn't mind using this product but at the same time it didn't seem any different than any other face serum, I didn't notice any difference in my skin after using this product.4
Love Kiehl's. Use many of their products daily. A very nice treat to get a sample size. I have used this product daily for 6 months and think it works great to reduce lines.5
The sample size wasn't enough for a continued use of this product, but for what I could use it really didn't seem to make that big of a difference, as the product claims to do.3
This stuff is seriously miraculous. I have crows feet and one fairly deep smile line at the corner of each eye and after less than a WEEK of this stuff, they are virtually GONE. I am shocked and thrilled and will definitely buy the full size when my sample runs out.5
