Q: What is the purpose of green-based cover-up? And where can I find it?
A: If you think about a color wheel, green falls on the opposite side of the spectrum as red. So, a green-based concealer or foundation will help minimize redness in the skin be it from a zit, a sunburn, or other irritation. For hiding blemishes, I like Physicians Formula Organic Wear Concealer Stick in Soft Green or Neutrogena Skin Clearing Concealer in Correcting Green (it has 0.5 percent salicylic acid to help clear zits, so don't overdo it, or you'll dry out the surrounding skin). Both will need to be followed with your regular foundation so the green doesn't become too obvious. To play down redness for larger areas, try Smashbox Photo Finish Color Correcting Foundation Primer in Color Adjust, which offers a sheer green tint. You can also transfer this color theory to other shades. For example, orange-yellow falls opposite blue, so anything with an apricot hue is effective at hiding veins or dark under-eye circles.
