On the way back, teen carefully squeezes spots (4)
I believe the answer is:
acne
'spots' is the definition.
(skin condition causing spots)
'on the way back teen carefully squeezes' is the wordplay.
'on the way back' is a reversal indicator.
'squeezes' indicates a hidden word (squeeze can mean to embrace).
'enca' can be found hidden inside 'teen carefully'.
'enca' reversed gives 'ACNE'.
(Other definitions for acne that I've seen before include "Skin disorder" , "Skin rash" , "(Inflammation causing) spots" , "Spotty complaint" , "Cane for the teenager?" .)
