Blusher (5)
I believe the answer is:
rouge
'blusher' is the definition.
(I know that blusher can be written as rouge)
This is all the clue.
(Other definitions for rouge that I've seen before include "Type of make-up" , "Make-up for rogue" , "actor may apply it" , "Powder for the cheeks" , "Cosmetic powder" .)
