You can go to your local gp and tell them that you're unhappy with your skin and what they would recommend to help fix it, that's what i did (even though my skin wasn't terrible, it could certainly use some improvement.
I was on a antibiotic called doxycycline and a gel called epiduo (this is what my gp recommended) that goes with it, which cleared up most of my acne, but the epiduo was too strong for my skin and would irritate it and my body got used to the doxylin, so i asked my gp for a referral to a dermatologist. she changed my antibiotics to Trimethroprim and an over the counter benzol peroxide cream
those are common treatments for acne, but yours a really severe, a dermatologist might even recommend doing roaccutane, but i suggest leaving that as a last option because it's very harsh on your body
