Concealing dark circles?

use a specific eye moisturizer that targets under eye circles. like merle norman cosmetics wrinkle smoother eye. don't like "wrinkle smoother" be offensive. I use it and i'm 20 years old. i use it because it REALLY helps tone down the darkness that i get from staying up late studying. i also use a concealer. use it morning and night. also merle norman has an eye GEL that you would use BEFORE eye moisturizer its called triple action eye gel and if you keep it in the refrigerator it will WAKE you up. its amazing, it helps with random puffiness that happens to everyone under their eyes. ALSO use a concealer LIGHTER than your skin color, and put right on the inside part of your eyes, like against your nose kind of. The lightness will brigthen your eyes. blend well though,
