Spots are circling near eyes, originally (4)
I believe the answer is:
acne
'spots' is the definition.
(skin condition causing spots)
'are circling near eyes originally' is the wordplay.
'originally' says to take the initial letters.
The initial letters of 'are circling near eyes' is 'ACNE'.
(Other definitions for acne that I've seen before include "Spotty coverage" , "Cane for the teenager?" , "Problem to face in" , "Skin condition prevalent among teenagers" , "(Inflammation causing) spots" .)
