Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have pimples and red marks on face which occurs due to hormonal changes, stress, when clogged pores of sebaceous gland filled with sebum ,dead skin and bacteria get infected. You are already doing so many things but not get benefited. I would suggest you to use product containing benzoyl peroxide. Persol forte creme as given to you could benefit to you and along with that wash your face with mild soap and cold water twice a day , exfoliate your face once a week. you should apply aloe vera gel and apply azelaic acid containing cream twice a day as this is safe and natural extract of cereals. Drink plenty of water and add fresh fruits and vegetables to your diet. If condition doesn t start getting better in a month then consult dermatologist Doctor may prescribe antibiotics course and along with that you can go for microabrasion and peeling. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
