If you have dark circles—like really dark circles—you know the poignant disappointment that comes from an eye cream’s failed attempt at lightening, brightening, and disguising those damned bluish half-moons. It’s something that all the concealer in the world couldn’t fix (at least not in the long-term anyway). Gleaning outside advice doesn’t always help, either. I’ve heard people recommend applying potato slices—even raw milk—to the under-eye area. While those things may have worked for them, I don’t have the time nor the patience for that kind of skincare commitment. I require something much more portable and much less perishable.
