I had particularly bad deep skin pimples, and also quite a few surface ones. I went to the Doctor once it started getting really problematic, and he prescribed me a 3 month course of 20mg Oratane Tablets. They're heavy duty and you need to have blood tests before being allowed to use them, as well as you're not legally allowed to father a child while using them due to the risk of deformities, but they have worked wonders.
Typically they can have relatively bad effects on your mood and dry your skin out beyond anything, but they usually come at 60mg tablets - and my Doctor found that by reducing it to 20mg it was just as effective as stopping acne, but not as viciously.
If your skin gets really bad, ask a Doctor about these or something similar; soap, face washes, and skin lotions never did a THING for me, and I would use them religiously.
