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.
Maybe this is only intended for night use? I tried it under makeup and it cause my primer and foundation to gunk up where I had applied it. I also didn't notice any obvious line reduction from using it.3
I think this would be a great wrinkle reducer but you would need the full size to determine if it works I feel.4
Okay I suppose, haven't noticed any real difference. The serum is runny, but seems to smooth when applied.4
I love the silky feeling of this product, the sample is not large enough to see results yet, but it feels great to apply prior to makeup application.4
I liked this serum, it felt hydrating without being oily. The sample is too small to know if the fine line prevention ingredients work.5
I've been using my sample the past fees days and so far I like it. It feels really nice on my skin. I'm hoping it does what it says it will do. I've been looking for a product like this that works but haven't found one yet.4
This is a light non greasy formula, which is great for wearing in the AM too. I use another serum but may add this to my regime.4
I've always been a fan of Kiehls products but hadn't tried this until now. A little goes a long way. Fine lines are definitely smoother with this on.4
I tried this, but it just didn't feel personalized to me. The product is obviously of a high quality, but is just not something I will use in my day to day routine.4
I use a serum every night and every morning and this one caught my attention. I really liked the smooth and light texture of this. I wish it wasn't so expensive.5
