If you are going to have photos taken, I wouldn't recommend touche eclat, as it's too reflective and you end up with reverse panda eyes. My favourite foundation is the Lancome Adaptive. It makes my skin look dewy and airbrushed, without looking heavy. I just use a cheapo concealer on my bags and it always works a treat when combined with my magic foundation.
Clinique do a concealer/illuminator pen which I have just bought and it good for under the eyes.
Also, No.7 do a concealer/illuminator which I thought was fantastic but make sure you get the right colour. I got the rose tinted on last time and it was wrongfor me. The ivory one worked perfectly. I am only trying the Clinique one as I was recommended it but its no better/worse than the No.7 IMO.
