The dmz will have altered your hormones natural state so it may take a little time for that to balance man.
Try to stay hydrated, at least 4 litres of water a day with no flavouring in it. Eat clean (no sugar products). If you are taking the accutane now give it time to act and you'll be ok.
I hate to say this but there is no quick cure, especially for cystic acne. Do your best to shower asap after sweating (don't sit around in sweaty gym clothes - go home and shower). Use a foaming facial cleanser on any acne prone areas. Avoid scented body wash or scented bar soap. Use a clean towel to dry off and wash your pillow case and bed sheets at least twice per week. Eat lots of leafy greens and get plenty of sleep.
You're body isn't happy right now so treat it well and let it balance out.
Try not to panic, you will heal and the scars can be minimized. Give it time and stay clean and hydrated.
