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.
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
love this product so smooth on my skin and refreshing5
I used this concentrate before bed until my sample ran out and I definitely noticed a difference in fine lines and the smoothness of my skin. I wish the sample was bigger! Perhaps I should consider purchasing...5
as I get older I have sleep lines in the morning (okay, they are wrinkles that are getting worse), this helped diminish the appearance of those "lines", so it gets 5 stars from me.5
I did like this product I have sensitive skin and it didn't hurt3
love the cream I will definitely buy it highly recommend it saw the difference5
Not on my list to order. Will not order in the near future.1
