My whole life (which began at 15 when I was allowed to wear makeup) I have been looking for a foundation to match my skin tone. Finding a foundation has always been difficult because of my ethnic skin, being that I am half Mexican, and half Ethiopian. I have always wished for a perfect match and I finally found one, with MAC prolongwear foundation shade NC 40. I am so shocked at how flawless and clear my skin looks. It looks like a magic eraser went over my face! Needless to say, I am definitely going to be a loyal MAC customer from now on.
