What causes acne ?

It is believed that acne runs in families. The episodes may flare up by:

• Hormonal changes occurring in menstrual periods, pregnancy, taking birth control pills and stress.
• Poor skin hygiene and prolonged and continuous dust exposure.
• Use of oily or greasy cosmetics or hair products.
• Certain drugs like steroids, testosterone, oestrogen and phenytoin.
• High level of humidity and sweating.
