Eg, rouge (8)
I believe the answer is:
cosmetic
'eg rouge' is the definition.
(I know that blusher is a type of make-up)
This is all the clue.
(Other definitions for cosmetic that I've seen before include "With surface effect only" , "Preparation designed to beautify the body" , "Facial preparation" , "Beauty preparation" , "Eg, make-up item" .)
