Hi There!
Agree with lady below manual lymphatic drainage is on of the best treatments for dark circle & puffiness under the eyes and it helps aid the removal of toxins,
Usually dark circles can be linked to the kidneys so drink plenty of water, lemon water is great especially in the morning,
Cold teaspoons is great! the cold increases circulation so it will help with puffiness.
I do offer a lymphatic drainage non surgical facial lift at my practice which really helps
