I'm not sure about creams to get rid of them but to conceal them you can get either a lilac concealer or a light reflecting concealer (touche eclat by YSL for example) and dab a little of that under your eyes then apply either a powder, foundation or a skin colour concealer over the top. The important thing is to dab a tiny bit of each, you can always add more but taking too much off can drag the skin and make the dark circles look worse.
