Hi, Welcome to HCM, You seem to have acne vulgaris from long time. That also relapses off and and on. There may be some factors which may precipitate or exacerbate the the disease. In your case, immunity might be deprived due to lung infection. Stress, anxiety,worries,sleeplessness,drugs like steroid and INH, travelling,sun exposure, oily food, seborrhoea,dandruff..etc may be the responsible factors. I usually treat my patients like you in following ways.. - to take antibiotic like minocycline or azithromycine in proper dose for few months or good result. - isitretinoin 5 mg daily at night till good result or side effect like cheltis. - to apply clundamycine gel in morning and adapalene gel at night on lesions. - to cleanse the face with antiseptic like cetaphil. - to avoid all suspected factors exacerbating the acne. You have to improve immunity with immunoboosters. If you have dandruff, do ketoconazole shampoo. You consult dermatologist personally and have perfect treatment. I hope this would be helpful for your treatment...ok Thanks. Dr. Ilyas Patel MD
