Is this a just a mark or a mole and will it go away?

Im lightly dark skinned and i have this black dot on my cheek, im a teenager and the black spot is small and would fit into a 1.5millimetre (mm) square, i know its small but is it a mole? Its flat and doesnt stick up and doesnt have a hair sticking out of it but its quite noticable. I also have alot more of them but very very tiny which you can only see at a face to face distance i was told these arent blackheads though i dont know what to think. Is the "spot" going to go away and what is it?
