End of sunbathing in Punta Negra? (3)

I believe the answer is:

tan

I'm a little stuck... Click here to teach me more about this clue!

'end of sunbathing' is the definition.
I can't tell whether this definition defines the answer.

'in punta negra?' is the wordplay.
'in' says the answer is hidden in the clue.
'TAN' can be found hidden inside 'punta negra'.

Can you help me to learn more?

(Other definitions for tan that I've seen before include "Catch the sun" , "Sun-kissed" , "Light brown colour" , "Sun-baked colour" , "Skin colour after exposure to ultraviolet rays" .)

I've seen this clue in The Sun.
