Hi Priyanka. I note with interest your history of acne. Although i dare say it is clear & precise, am afraid much more needs be asked before one can opine. Firstly are you married, sexually active or/ & expecting to get pregnant in the near future? Are there any hormonal issues like PCOD (polycystic ovarian disease) in you or a family history of the same? Are you willing to try a systemic /oral medication to be taken for a minimal period of 6 mths? This medication in my mind is oral isotretinoin & has a lot of side effects & contraindications & we can go through them in detail along with the blood tests et al to be done as per protocol if one decides to go through with this. However, for all these asessements, it is best that a dermatologist on the ground see you as opposed to online treatment as the treatment is tailored for individual patients I hope have pointed you out in the right direction for a definitive cure & do hope the results are satisfactory & you soon have an acne-free skin!! Here s wishing you good health & an acne free countenance! Cheers! Dr Praveen Rodrigues MD
