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 honestly didn't see a difference using this serum. I think I really need stronger acid serums in order to reveal my best skin. I'm not a fan of Kiehl's in general - I think most of their money is spent on marketing, not on the actual products themselves.1
Love all Kiehl's products!
Used it before I put on my tinted moisturizer every morning! A great product to use day or night.
Although the directions indicate not to apply around area, I read them a little too late and wound up doing just that. I did notice that after just 2-3 days the difference in the fine lines I get underneath my eyes were less noticeable.5
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.4
I have a mid size deeper wrinkle on my forehead between my eyes. I used this just on the area of deeper wrinkles. They disappear. I use it in am and pm ....concentrating directly on wrinkle/trouble spots.5
I'm 31 and starting to get some smile lines around my eyes. I was happy to get this sample and I used it every night until it ran out. It felt soothing and nice around my eyes, but I didn't really notice a difference in the appearance of lines. It did feel nice and warm going on though, so I'm sure it was doing something -- maybe preventative for further development of line, but I couldn't really tell. Maybe if I'd used it longer.3
I was pleasantly surprised by this product it made a bug difference on my fine lines, and I felt more well-rested just by wearing it!4
this ace skin firmer has been shown to improve elasticity by 50 % LOVED THIS PRODUCT i HIGHLY RECOMMEND TO ALL!!!!
I loved the fact that it heats up as you apply it.
Seems to really get in there instead of just laying on your skin all day and never really doing anything
slow process but shows improvement with time. Does not smell good. Not very impressed compared to other things I have used.3
