Hi,

The first thing you have to do is avoid eating too much of oily and deep fried food. See to that you have a balanced diet consisting of carbohydrates, vitamins, minerals, protein, calcium. You will find all these in green and leafy Vegetables, fruits, milk and dairy products etc. When you consume a banana don't throw the peel instead gently rub the inner part of the peel over the pimples. Keep it like that for some time and wash your face. Keeping doing it for a month and just wait for the outcome.

I hope this is useful.
