Face covered in spots, son not caring (8)
I believe the answer is:
reckless
'not caring' is the definition.
(reckless means careless)
'face covered in spots son' is the wordplay.
'face covered in' means to remove the first letter (the word's first letter is its 'face').
'spots' becomes 'freckles' (freckling is a kind of spotting).
'son' becomes 's'.
'freckles' with its first letter taken away is 'reckles'.
'reckles'+'s'='RECKLESS'
(Other definitions for reckless that I've seen before include "Dangerously rash" , "Irresponsible" , "Imprudent, rash" , "Without thought for the consequences" , "Devil-may-care" .)
