i think if u suddenly have a lot of ance on your face, it is your hormone problem, no matter how to wash your face, it doesnt work on those ance ga, you should see doctor first and they will give you some medicine on it.
I did once before as well, and after i ate medicine for a month, my ance almost all gone, that product is birth-control pills for balance the hormone, it is really work for me cause my ance problem mainly because of my hormone problem.
but just girls can eat the birth-control pills, if u a boy, you cannot eat.
