I don't have very bad dark circles but some discoloration and puffiness. Someone gave M. the new l'oreal collagen micro pulse thing. I don't particularly like the way it feels, but I noticed and other people commented that there was a notable difference after a week of using it. There are always coupons for it in the newspaper and sales, but I think it retails for about $15. It might be worth a try.
