Hello there. Since you are aged only 22, the type of acne you are suffering from is of hormonal imbalances. In a year of two when things start becoming normal, you will be rid of the acne. Till then drink lots of water as you are already doing. Avoid oily and spicy foods, and wash your face thrice a day daily with a mild soap or a good face wash. And follow the treatment given by the dermatologist. Hope this helps. Regards
