# If you normally use foundation , go ahead and apply it as usual. The wash of coverage provided by foundation will even out your complexion and eliminate at least a bit of the problem, showing you exactly where you need to apply concealer.


# Apply concealer to the darkened areas. Not your regular concealer, but one that you've acquired especially for this purpose. If the circles under your eyes tend to be very purple, use concealer with a yellowish tone. If the under-eye circles are blue, get a concealer that is more orange colored. Reddish circles? Grab an olive-based concealer and if your circles have more of a brownish tone, try one with a blue or mauve shade. These concealers will look funny in the tube, but when they're applied to your dark circles you will immediately see their neutralizing affects. It will still look a little off, but your eyes will look remarkably better after the final steps…


# Powder the area under your eyes with very fine translucent powder to set the corrective concealer, and then go over the area one more time with your regular, everyday concealer (the one that matches the rest of your happy, non-discolored skin).
