Beneath spot, perhaps, delicate skin here could develop dark circle (8)

'delicate skin here could develop dark circle' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'beneath spot' is the wordplay.
I cannot quite see how this works, but
'beneath' could be 'under' (under means beneath or underneath) and 'under' is present in the answer.
'spot' could be 'eye' (both can mean to notice or observe) and 'eye' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'perhaps' is the link.

Can you help me to learn more?
