Just look at your Mom or Granma to check if they have dark circles under their eyes, too. If yes, your under-eye puffiness is, most probably, a hereditary condition that runs in the family. If not, you may have a unhealthy diet, or sleep too short.....
And the eye cream my mom use is *** Code All-star *** Oxygen Eye Cream, she is 49 years old, and still looks young! so that's why i recommend to you since you don't care how much you'll spend. *** CODE is a luxury brand in New York, only served for club members like celebs and rich women. it's a customized skin care product, as it may get banned by putting links in my reply, you can find the official site online and have a look.
