These gold eye patches are lovely...I'm not certain what the product claims to do, as far as diminishing dark cycles under eyes, but I didn't them for that purpose, anyhow.  I like to use them if I wake up with puffiness under eyes....for that they work very well. Has a nice cooling effect and leaves under eye area moisturized...has a slight; pleasant scent.  Takes a bit of maneuvering to get them in the right position under eyes, but they do stick and stay in place after applied. I feel like this package will last me a while. Packaging/product bigger than I expected!  but, will repurchase, again.
