Hi,
You said you suffer from 
acne vulgaris. It is a multifactorial disease. There may be different forms of acne like comedones,papules,pustules or cystic lesions. 
Stress, anxiety,
sleeplessness,drugs like steroids,oil food,dandruff..etc might exacerbate the disease.
 I can understand your anxiety for acne. But, please have patience for the good result. Avoid stress and worries. Take good sleep. Avoid oily food.
You may take antibiotic like 
minocycline 50 mg daily in morning or  azithromycine  500 mg three tab per week..daily for three days in a week.and 
isotretinoin cap in low dose of 5 mg daily at night . Zinc and vitamin C tabs would be helpful for clearance of the acne lesions.
Apply clindamycine gel in morning and 
adapalene gel at night. Cleanse the face with antiseptic like acmed face wash.
Have pateince for the result. It may take few months for the good result. I hope you got my answer.
Thanks.
Dr. Ilyas Patel MD
