Reconstructed by police with newer aid to facial definition (7,6)
I believe the answer is:
eyebrow pencil
'aid to facial definition' is the definition.
'reconstructed by police with newer' is the wordplay.
'reconstructed' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'by'+'police'='bypolice'
'bypolice' put after 'newer' is 'newerbypolice'.
'newerbypolice' anagrammed gives 'EYEBROW PENCIL'.
(Other definitions for eyebrow pencil that I've seen before include "Cosmetic in stick form" , "Cosmetic item" , "Cosmetic applicator" .)
