Teen carefully squeezes returning spots (4)
I believe the answer is:
acne
'spots' is the definition.
(I've seen this before)
'teen carefully squeezes returning' is the wordplay.
'squeezes' indicates a hidden word (squeeze can mean to embrace).
'returning' says the letters should be written backwards.
'enca' can be found hidden inside 'teen carefully'.
'enca' reversed gives 'ACNE'.
(Other definitions for acne that I've seen before include "Cane for the teenager?" , "Spotty complaint" , "Skin rash" , "(Inflammation causing) spots" , "Problem to face in" .)
