Re: FOUNDATION!
They solution to your problem is a foundation with light reflecting particles- think Touche Eclat by YSL. The particles in the foundation reflect light back (don't know where!) and give the illusion of a clear, glowing complexion. I know people who use liquid foundations with light reflecting particles and their skin looks lovely! Their pictures at parties/weddings come out GORGEOUS too mashallah. Try going for a shade that is your exact skin colour or one shade darker (shock horror!). I've found that some Asian people try foundations that are lighter than their natural skin tone and this can make their skin appear ashen and dull.
Hope this helps. x
