hello vikrant. here are a few things you can do at home. 1. drink lots of water, keeping your skin hydrated definitely helps in such cases. 2. wash your face thrice a day with a mild soap or facewash as oily skin is more prone for pimples. 3. avoid oily and spicy foods. 4. have lots of greens and fruits. 5. apply clindamycin gel twice a day if it still persists after all this. you will have to consult a dermatologist. he will assess your case and help you with further treatment. you could also go for chemical peeling that also provides good results. regards.
