Mistake: Applying an Off Shade

Choose a concealer in the wrong color—going too light, for instance, to counteract those dark patches under your eyes—and you could end up with these distinctive reverse-raccoon half-moons. In general, match your skin tone or go just a shade lighter, but no more than that. If you have under-eye circles, a concealer that has a yellow or peachy tone will neutralize the circles’ purplish cast, warming and brightening the area. Be sure to avoid anything with a green base, which will only accentuate shadows.
