Hey there,
I've been stuck with this kind of acne since about a year after my accutane treatment. Accutane cleared my face up entirely but ever so often I get a flare up that looks like in these pictures, that calms down a little and flares up again. I am using very minimal products, just a face wash (tea tree oil) and moisturizer (with salicylic acid). This worked fine after my treatment but now it doesn't seem to be doing anything. I bought a BP spot treatment that I applied at night but it made things worse. I don't know what to do to fix this problem but It feels like if I can figure out what's wrong it will solve the issue. Is it possible that my face is just too dry (using BP dried it more and more acne came)?
I randomly came across sulphur soap on amazon I had never heard of it before. It's the best product i've used for cleaning my skin. I wash with it twice daily and along with my antibiotics it seems to really help with spots/scars. The bar of soap lasts for months as well.
