Please help me correct or hide my dark circles under my eyes. i've tried hundreds of creams and concealers.

Obagi's Neotensil : There is a new "fix" on the market from Obagi called Neotensil. It is a temporary treatment that improves the appearance of bags, wrinkles and dark circles under the eyes. Also being called "spanx" for under the eyes. A good alternative to cosmetic surgery, however, a bit pricey, but you can use it daily or just for special occasions. Worth a look, better than most stuff out there!
