acne? allergy?

Oolaa
Does anybody know what this could possibly be i alwayd have it..at one point i thought it was because my period was coming but it has just stayed that way, i did try putting acne treatment on it but it doesnt go away, i do wash my face very often and take good care of it anybody has any clue or suffers from a similar thing? I am 17 years old and take the pill but before my skin was horrible it has improved however latley its just not been the best..
