Hi and thank you for your question.
Hormonal breakouts definitely tend to cluster around the mouth and jaw line and are caused by the changing influences of testosterone and progesterone on the skin.
It is possible that the oral contraceptive that you are on is too mild to control the hormonal fluctuations completely and you may also require a short course of anti androgen therapy too. Speak to your doctor about these options. You should also consider changing your monthly facial routine and daily home care to concentrate on gentle exfoliation and oil control, which you can discuss with your therapist.
Wishing you a quick recovery.
