Acne

My acne is aggravating not because of anything but merely due to continuously outbreaking new pimples on my face that continue and seem to be forever . The problem is that most of them dissapear within a weak but new ones continue to emerge.How can i stop them? Please recommend any internal body medicine that could stop it from growing more and more.( I don't touch the face often while washing or normally wash pillow case after a week or two)
