Hey I didn't notice them the other night at the dinner!

I have two shades of foundation (Clinique, a moisturing one). I use the two shades to conceal my panda eyes too. I also agree that the best remedy is lots of sleep. But it can be hereditary, if so there might not be a lot you can do.

When buying a good foundation get a professional to match it for you so you get an accurate shade. Most high end cosmetic brand sales assistants at Myer do this. Make sure they test it on at least two places, jawline and maybe over a bit of the dark circle. Also buy a moisturising one so that it sits nicely. You don't look like you have oily skin.

If you find and use a foundation that is right for you then it makes you feel 100%. Sometimes it can be hard to find one light enough (most are too dark for me and I'm not as fair as you).
