I would consider myself a medium/light skinned african american girl. (like Beyonce or Halle Berry) I've recently started experimenting with make up a bit more. I bought 3 shades of concealer, Light/Ivory, Light Medium, and Medium, all Loreal. It seems like the Ivory would be way too light...but i can't tell if it looks bad or not when I use it. The Light Medium looks ok...i think. I was wondering, what would be the outcome if I used the LIGHT concealer...would it look too weird?

Yeah, your face will look washed out. If you can't get one exactly, try mixing two or more together until it works. Make sure you look in the mirror in natural light.

yeah you have to find one that matches your skintone
