Unfortunately we cannot stop the hormones present for the acne. It is triggered by excess androgen hormones and testosterone. There is testing for hormone excesses available.
In most cases, it is caused by hormones disorder and wrong food.Try to have a regular life and healthy diet.You also need to relax at any circumstance.
The hormones afects your mind... what makes the acne is the hot and sweting thing. So u can wash your face with fresh water before go to bed or even during the day...:)
