I received this as a sample with a purchase from Lancome and used it for several weeks. I tend to sleep late so I have dark circles and small bags underneath. During the time that I used this eye cream, I did not see any visible improvement in the delicate skin underneath my eyes. The cream did help a bit when it came to eliminating puffiness after late nights, but the change wasn't significant enough to justify the purchase price. In terms of the product, the cream is slightly viscous which makes it easy to apply, but it doesn't absorb into the skin very easily and left a slightly greasy/tacky feeling behind, making it less than ideal for use under makeup. Also I think the product tended to block my pores since I got several obnoxious under-eye pimples during the period of use. Overall I think this product, like many other anti-aging serums that are promoted on the market, is being hyped up as a revolutionary new product when it's really just another bit of gunk in a small pot. At the end of the day, regular sleep, lots of water, and quitting smoking is the key to eternal youth.
