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 this one from Kiehl's. Loaded with vitamin C and other potent ingredients, it smooths, brightens, and tones skin.
I was sceptical after reading the bottle, but it really does work. Fine lines vanish.5
My skin is dehydrated at the moment and it's starting to show some lines. This Concentrate is helping me moisturise my skin very efficiently. I couldn't say that it removed my lines (yet!), but it drastically improve the elasticity and texture of my skin. It looks better and fuller.4
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 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
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've started to develop little lines on my face and was very excited to find this product in my box. After several nights of using this sample, I can honestly say I didn't notice a bit of difference. I'm still searching for a product to help with my fine lines1
This stuff was so amazing! I thoroughly enjoyed it! It had the nicest feel on my skin 10/105
I really like this serum and was glad to see it in my box. I think I'll use the rest of my sample when it gets a little colder to see if it helps my skin.4
Great for after masking. Tingling action helps you to feel like product is working that much harder. Thinking about purchasing full size4
I originally purchased this products years ago directly from keilhs and I used it just a few times. The product never felt like it absorbed into my skin and I think it might have been responsible for breakouts. Love this brand though so if your skin is super dry it might work for you.2
