Gives a different face (6)
I believe the answer is:
visage
'face' is the definition.
(I know that visage is a type of face)
'gives a different' is the wordplay.
'different' indicates anagramming the letters (letters placed in a different order).
'gives'+'a'='givesa'
'givesa' is an anagram of 'VISAGE'.
(Other definitions for visage that I've seen before include "Clock" , "Face, aspect" , "Mug" , "A person's face, countenance" .)
