Can I use skin lighteners under my eyes for dark circles or are my eyes to sensitive? I know that liquorice has anti inflammatory properties, would that help for the puffiness

God, no, don't use licorice !

But... good product now on the market that I started using is Garnier (green wand) for under eye darkness and circles that has caffeine and a wonderful stainless steel ball that has a cooling effect. Goes on night and morning.

This is not advertising. I particularly enjoy the results, that's why I am plugging it. Very expensive here in Canada though, but worth it.
