I've had a quick look around,
And other than using a ferrofluid sandwiched between two inert membranes
or a black stained wax manipulated by alternating heat pads on your face, I can't even begin to solve it.

*looks around for ferrofluids*
Might not need heat pads if you can get the melting point of the wax down to facial body temperature.
