I have been using MAC Select Cover-up for years and I use it almost every day. It never lets me down. It is the perfect concealer for hiding dark circles and blemishes. It excellently evens out my skin tone. Just don't overdo it or else it will end up being cakey and oily. Make sure to blend it well also. I use MAC Cosmetics Pro Performance Sponge to apply it. Afterwards, I use MAC Select Sheer Pressed Powder for a silky natural finish.
