Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have acne on face due to hormonal disturbance which are very common in your age group and occurs due to onset of puberty, hormonal changes and when clogged pores of sebaceous gland filled with sebum ,dead skin and bacteria get infected. You can take this medication before that you should get your hormones levels monitored. You should wash your face with mild soap and cold water twice a day. You should use Isotrentoin on daily basis and wash face with clindamycin gel. If condition doesn t start getting better in a month then consult dermatologist/ gynecologist once . Doctor may prescribe antibiotics course. Drink plenty of water and add fresh fruits and vegetables to your diet. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
