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.
This product proved to be a good skin moisturizer after my cleansing routine but it tended to burn my eyes for several minutes after application. This is concerning, considering most people form lines around their eyes more than any other area of their face.3
After I wash my face and moisturize, this stuff is a must around my eyes and critical wrinkle spots. It really does smooth out my skin.5
It goes on nice and light, feels a little warm when first applied, however it did not irritate my sensitive skin. This product made a noticeable difference in my skin within a day or 2. I am 52, with lines and sun damage, so yes I could notice! Fine lines were reduced a bit, and skin tone looked smoother. I will buy the full size, even though it's a little pricey. Great product, quick visible results, no irritation.5
I have used this product just for a few days and it has already made an impact. I will be ordering this again!5
This is the most surprising line-reducing skincare product that I have used. Why? I was able to see a difference just by using a small sample. I am very excited about this product and will definitely purchase.5
Great brand and I absolutely love this type of product4
I love Kiel's products and this is no exception, but I am loyal to my Caudalie S.O.S. serum and I'm not ready to make the switch.4
Perfect for that quick lift on the go. I absolutely love it. Thanks Birchbox! I would order this again.5
I'm 30 and for the past two years, face & eye moisturizing has become a part of my nightly routine. This serum felt quite nice, but I really couldn't tell any difference. Smooths? Not noticeably (and I have a 3x magnifying mirror). Brightens? Possibly. Again - really couldn't tell. Worth it? Meh - I'd say no.3
I used this product every night and saw a real difference in my skin! It looked smoother, and definitely brighter. Worth the $$$$!4
