I had moderate acne as a teenager and was eventually treated with roaccutane when antibiotics and topicals failed- this cleared my skin for a few years but spots started to appear again about a month after stopping Yasmin birth control (or at least I put this down as the most likely cause).

After racing back to the doctor in fear of it getting worse I have been on Dianette for the past two months and have been using skinoren cream for 4 weeks- the good news is it hasn't got any worse and I only get one or two spots at a time, BUT about 3-4 times a month I get these gigantic under the skin spots which are extremely painful, swollen and embarrassing, take weeks to go away then leave a dark red scar which takes forever to fade mostly around my mouth and hairline but occasionally on my forehead, back or neck

For what mostly looks like mild acne (see photo 1 + 2 = no active spots just bad red marks), why do I keep getting these awful cystic things?! (see gross photo number 3, hurts like hell!)

It's like a weird combination of mild and severe acne?? I'm trying to avoid all-over BP and retinoids when my skin is already dry and red, any suggestions? Am I going down the right path with dianette?
