Fasting is not good to clear acne because you lose a lot of the nutrients your body needs. Detoxing your body along with balancing your hormones will cure all your acne. Drink a lot of herbal teas and supplements. You can find a lot on the internet. good luck
I did a water fast for 4 days and had an extrem breakout the worse I've ever had so I wouldn't recommend this. However, I talked to a naturepath that told me that he fasted for 2 weeks on the first week he broke out really bad as well but on the 10th day most of his acne had cleared up but he said this fast was supervised by a doctor
