Compensated cosmetically (4,2)
I believe the answer is:
made up
'compensated' is the definition.
('make up' can be a synonym of 'compensate')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for made up that I've seen before include "Not true" , "Supplied" , "Invented" , "Put together" , "painted" .)
