Blackhead problem on my forehead, help?

I've always had black heads on my forehead, but recently it sees they've made my forehead look bumpy. Honestly, it looks like a rocky road. This wasn't an issue at all before, they were there, but my skin looked...flat. I've tried using exfoliating subs but it doesn't seem to be helping. I don't break out very often, and when I do it's usually just a few. The problem is just that it makes my forehead look bumpy and I want to get rid of the bumpiness. Does anyone have any ideas? Should I do facials or something? I'm clueless.
