best products to fight dark under-eye circles...

I have decided to add a new weekly post catering towards Flawless Beauty reader questions. So if you have a product or skincare concern, send me an email or leave a comment and I will do my best to find you an answer! Thanks Karla for the first question!

Just wanted to ask your opinion on the best eye cream for dark circles? Do you have any recommendations?
I have not had a chance to personally try all the below products but these seem like great choices. If anyone else has any recommendation please share!

Available at Sephora, Lotus Eye Gel is a cooling, light formula that alleviates puffiness, dark circles, and signs of fatigue with a unique combination of highly developed and preventative botanicals. The main ingredients sound wonderful. Umbrian Clay, Lavender Water, White Nettle, Olive Leaf Extracts...For a concealer like effect with SPF 6 try Korres Evening Primrose eye creme.

People have given the eye creme charged with tourmaline from Aveda rave reviews. This also dries matte making it perfect for seamlessly application underneath make-up.
Another beauty trick? Apply a dab of tinted moisturizer a shade lighter than your skin underneath the eyes (make sure the color is lighter) to lighten up the circles. Be sure to also get a good ten hour sleep in!
