The problem you were having is termed as cystic modular acne
variety as per your symptoms you told , all the medicines u were using will be good enough but continuous usage of oral antibiotic drugs is not recommended , acne is a very common problem in teenagers so you need not worry much about it , because of hormonal
changes in teenage the condition is very common , you take care of your face by washing with gentle mild soap like Johnson baby soap twice daily and avoid excessive oily foods .
Regarding treatment wise there are lot of new treatment modalities today , better you take a good dermatologist
consultation. Even with utmost care , chances of recurrence is very common for acne and this last until you reach 25-28yrs.
Take care bye
