Terrible skin texture - will roaccutane help extremely clogged pores? (Photo)

I have terrible blackheads everywhere which look like extremely large, dirty pores. I have put up with these for so long and I can’t remember a time when they were this bad. I can squeeze my cheeks/forehead constantly and sebum comes out, however the pores always end up becoming clogged again. I have just started roaccutane and I take two 20mg tablets a day. Will roaccutane have a direct effect on my blackheads at all?
