What is the cause of this acne?

[random12345678 0]

My skin always struggles with occasional breakouts. I’ve been using the ordinary ascorbic acid+ alpha arbutin serum for a few weeks (I’m not very regular with it). I had some acne before I started using it too, but not much. And I’ve had these tiny bumps come up for a bit and then go away… but now it’s back with a vengeance almost overnight. All I use is this, a face wash, a moisturiser and benzoyl peroxide on my acne at night. Can someone tell me what his is or why all of a sudden I have this acne all over? Is this skin purging or a reaction or just acne? What do I do?? I am at my wit’s end.

I would suspect one of the products might be at fault. Products can cause breakouts a couple weeks after you start using them. 

Tried the regimen yet? That should get you completely clear.
