Forehead bumps, what are these?! (photos)

I've been getting these small colourless bumps on my forehead that have been multiplying. I went on epiduo and it kind of kept it under control to a degree but when I came off it the problem got worse and then going back on it just irritated and made my skin itchy so I stopped using it all together. I exfoliate twice a day to wash my face ... Is that wrong? Should I be using cleanser to wash my face and exfoliate weekly? I keep switching my skincare routine and it's making my acne worse.
