I have combination skin (oily/dry) and use the L'Oreal Paris Infallible Full Wear More Than Concealer daily #350 Bisque. It covers blemishes well and is easy to blend in. The concealer is creamy rich and a little goes a long way. I no longer use foundation. I set it with powder. The concealer is available in many colors and when I can't find the #350 Bisque, I use the #345 which is a little lighter, but it still looks great.
I highly recommend this product.
