Acne/Pimples on face from last 3 years.

I am facing issues of pimples on my face from last 3 years. It has become really bad now with so many acne scars on my face. I get all kind of pimples, whit heads, reddish hump kind, white top and full of puss. I have tried dermatologist before where anti biotics like Azithromycin 500 and  isotroin was suggested but did not see much difference as pimples kept coming back. I then tried homeopathy for 8 months and it still did not help. Looking forward for any suggestion on going forward and how can i cure my acne amd pimples. I am a Male 33 years of age. Eating habits are good with less oily andspicy foods, no packaged foods. Drink water 3 litres atleast. Eat salad fruits. I workout regularly. I am clueless as to how to cure my acne. Any guidance would be of great help. Attaching some pictures showing current state and last 3 months state. Lot of marks and scars is todays state. Thanks Rajat
