Injury's aftermath (4)
I believe the answer is:
scar
'injury's aftermath' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scar that I've seen before include "Visible mark of healing" , "Disfigure(ment)" , "Cicatrice" , "Mark left by the healing of injured tissue" , "Mark left by old wound" .)
