I put it on one eye to see if there is a difference, and the skin around that eye is now noticeably softer than the other eye. But it did nothing for the dark circles or puffiness. I think this product would multitask as a solid moisturizer for your face. It feels good when you put it on. But will most definitely sting if you have sensotive eyes. I used it for about 2 weeks and my eyes have now become accustomed to it. The bottle is very heavy and i love the quality packaging. It's very esthetically pleasing. I will not repurchase because i look for eye serums that help get rid of puffiness better.
I recommend it as a moisturizer and not so much an eye serum.
