Face contouring. Does anyone do it? With what products?

[curiositykilledthekat]

I have just stumbled across some you tube videos about face contouring (a la Kim K and J-Lo), the people on there make it look really easy but the before and after results are stunning.

So do any of you do it? I kind of get the whole bronzer bit but not too sure what to use as a highlighter?

I think I need to invest in some decent face brushes too.
