Acne is caused by bacteria. Hormone, diet, lifestyle, habit are secondary factors that causes acne.

Re-look into your lifestyle or habits. First thing to tackle is hygiene. Wash your towels every few days, change your bedsheet, pillow case etc every week. Think back carefully, what often come into contact with your face e.g. fingers, phones, pens, any objects etc? Refrain from doing those.

Then look into your skincare routine. Understand what you're putting on your skin & what are their function. Everyone's skin is different & it changes from time to time, that's why there's a million different skincare brands out there for different needs. For acne, focus on antibacterial stuffs, something to control the sebum level & something that promote cell regeneration to heal existing acne.
