Sign of long term skin damage breaks men apart (8)
I believe the answer is:
permatan
'sign of long term skin damage' is the definition.
I know nothing about this answer so I can't tell whether this works.
'breaks men apart' is the wordplay.
'breaks' indicates an anagram.
'men'+'apart'='menapart'
'menapart' is an anagram of 'PERMATAN'.
Can you help me to learn more?
(Other definitions for permatan that I've seen before include "Hollywood star may have this" , "Bronze not going" .)
