It is Bourjois' poudre illuminatrice aka highlighting powder.
This consists of highly concentrated doses of irridescent mother-of-pearl for a subtle, luminous finish. The product itself resembles a bar of chocolate with a hint of chocolate scent which I find doesnt last once applied.
I havent come across this product in any of the stores in the UK though I have seen the bronzer version in Superdrug and Boots.
Here I have paired the Bourjois highlighter with MAC's well dressed.
This product is amazing and cost me about £4. It just goes to show what bargains you can pick up on ebay when your not really looking.
Has anyone else tried this before? I'd love to here your opinions.
