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 have been using this product for 3 or 4 years now. Helps with fine lines. It's hard to find a vitamin c product with a pump. Ascorbic Acid (vitamin D) breaks down very fast chemically when exposed to air. So it's important that it comes in a pump. Love this products!5
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 love this brand, everything I've gotten from them, I've been happy with. Their cost is at my ceiling for skin care but once I decide to make the investment, I never regret it but I always wince a little when I do it.5
This feels nice on the skin, though I can't really tell if it is doing anything other than adding a little more moisture. Good for sampling, but not sure if it's worth purchasing, especially for how much it costs.4
no weird smell. Goes on great and works very well. I was very sceptical at first but it actually works.5
I love the feel of this product, goes on so smooth. I have not noticed any improvement in my almost 60 year young skin, but am hopeful.4
