Pimples increase when you take high protein diet (meat, eggs, milk products), high calorie food (sweets, fried food). Medicines are available for treating these. It will take about 3 months for the acne to clear up. I starty patients on creams to be applied daily and add tablets only if the response to the cream is not enough or they have very severe pimples/acne. Procedures like chemical peel are very expensive when done on large areas like back so creams and tablets are a better solution. Hope this helped you. Please visit a dermatologist near you for treatment. Warm regards. Dr. Rajdeep Mysore. Chirag Hospital Bangalore
