The cool corrective cream pastel palette (green,pink,yellow.blue) is absolutely brilliant for little areas of the face with demarcation I found the green excellent around a red nose in the winter, and the yellow under my dark eyes. However, it is a little greasy and doesn't like to be set with anything, as this makes it cake. So best to apply and maybe add some foundation on top, leaving your setting powder off.
The Elf Concealer Pallet has everything you need to get the illusion of perfect skin. The green concealer covers up blemishes, the pink for dark circles, and the two skin colors over to make them look natural.
