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
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
Loved it. Very lightweight and did not effect my sensitive skin. I recommended this to everyone I know.5
Not sure I would buy this because I can't see results from the sample but fees nice putting it on.4
OMG I love this product and plan to buy a big bottle! It goes on so smooth, and instantly makes my face look brighter. I can apply it as many times a day as I want and I can sleep in it. I love the consistency. I can see a difference just using up the small sample.5
Really? This is basically a bunch of silicone-based gunk to give the illusion of smoothing the skin, with some Vit C thrown in. Adenosine might be a great ingredient too but not worth putting the chemicals on my face. I get a fully natural C product with many more skin-nourishing ingredients for so much cheaper than the full size of this is being sold for. Also the sample was so tiny that there wasn't nearly enough to assess efficacy even if I had really wanted to.1
I loved this serum. It went on nice and smelled great.5
Like all Koehler product this product is great. It is not greasy and it really feels great on the skin.5
