Color correcting under eye darkness is easiest with a color correcting palette. You will need something with a yellow, orange, and peach color to correct the blueish-purple tones. It can be weird getting used to putting weird colors on your face, but this does work. By the time everything is blended out, most of your problems will be easily camouflaged. I personally use the same two palettes for everything related to color correcting and they work out perfectly for my needs. For this post I used the Stila All in One Correct and Perfect Palette, but I also like the NYX palette if you’re looking for a drugstore alternative. Find it here.
