Hi.. As you said you are having acne vulgaris from 3 years. I would like to share knowlegde about acne.There may be different forms of acne..like white comedones,black comedones,inflammatory acne, conglobet and cystic acne . Acne vulgaris is a multifactorial disease. There may be some cause. Stress,anxiety,oily food,dandruff, sleeplessness, hormonal imbalance,drugs like pills,steroid ..etc may cause or exacerbate the disease. Genetic tendency may be there.Oral drugs along with topical applications might improve the lesions.You consult dermatologist. I advise in my patients having acne as below.. - to avoid all suspected factors which stimulate or exacerbate the lesions - tab azithromycine 500 mg thrice a week 24 hourly consecutively for few months Or cap minocycline 50mg daily in the morning till good result. - tab isotretinoin 5 mg daily at night - clindamycine gel or adapalene gel to apply at night on lesions only -cleanse the face with antiseptic face wash like acmed. Have patience as the good result may be there after few months. And relapse may be prevented.I hope you got my answer. Thanks. Dr. Ilyas Patel MD
