Facial cosmetics (4-2)
I believe the answer is:
make-up
'facial cosmetics' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for make-up that I've seen before include "Composition - cosmetics" , "Constitution" , "Cosmetics applied to face" , "Facial cosmetics" , "Lipstick, mascara etc" .)
