What to do if i have really bad acne and blackheads, what's the best way to get rid of them?

Scientific rx: This is too severe to use just benzoyl peroxide though it is likely to help. Physician's office visit. Options may include topical retinoic acid derivative (choice 4 blackheads), topical clindamycin, the oral contraceptive pill for a woman who can take it, and/or an appropriate systemic antibiotic right for the patient. Tough cases referred for isotretinoin. Manage as a chronic disease. Good luck.
