Its hard to say but there are other option. of course: photodynamic therapy with levulan, spironolactone, birth control. Blue light therapy, with or without levulan or another photosensitizing agent, may give improvement but does require a time commitment for blue light alone on your end (twice weekly/ 20 minutes per treatment). I am a big fan of alternating blue and red light for treating both the acne and the redness from the inflammation. Being siad, there is also a great place for isotretinoin..
My hunch is that you need to have blood work done to check your hormone levels/ ensure you dont have PCOS....too much for this forum but the best advice is to see a dermatologist!
