Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have pimples and pigmentation problem which occurs when there is hormonal changes, stress and clogged pores of sebaceous gland filled with sebum ,dead skin and bacteria get infected. You are already taking so much medicine but getting recurrence of symptoms as well. I would suggest you to make use of product containing benzoyl peroxide. Drink plenty of water daily and add fresh fruits and vegetables to your diet. Take Multivitamin supplements. Apply Adapelene gel once at night. If condition doesn t start getting better in a month then consult dermatologist. Doctor may prescribe antibiotics course and can also go for chemical peel containing Glycolic acid. Also wash your face with mild soap and cold water twice a day , exfoliate your face once a week , apply aloe vera gel and apply azelaic acid containing cream twice a day. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
