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 has been an amazing product! One of the best serums I have ever used. Definitely would recommend to anyone as I notice a huge difference! So glad this was in my BirchBox!!!5
Great product great smell great lasting results I love this very effective clean smell great feeling great resulresult5
I love the way this concentrate makes my skin look and feel. It's moisturized and I felt like the fine lines were softer after using it for a week. I ordered a full sized bottle!5
Product worked very well and a little goes a long way. Continued use provided a nice condition for my skin.5
Sample wasn't really large enough to get a good idea of how this would work but it did feel nice going on and I think some fine lines may have been reduced. Smelled great too.4
The serum isn't greasy because it has a creamy consistency which I love. I've been using this everyday and plan to continue!4
I wouldn't say I am old but 35 isn't 20's. This is a good product, it works so far and there is no smell to it which is a plus5
At first this stung m6 sensitive skin. Be advised don't get to close to your eyes. Made mine water a bit. It made my skin feel very hydrated. Smoothed wrinkles just a bit.3
Feels very greasy at first but absorbs in skin instantly. I really feel like this worked. It made my skin feel soft and hydrated without feeling greasy.5
These types of samples don't really work well for oily skin. Its pretty difficult to see any change with the amount of sample provided. I wouldn't both with it.3
