What are very effective ways to get rid of acne fast?

Scientific Rx: Two weeks trial of topical benzoyl peroxide alone. This clears most mild acne. If not clear, physician's office visit. Options may include topical retinoic acid derivative, 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.

See Dermatologist: Best to be seen by a well experienced board-certified dermatologist; nothing replaces in person history and physical when it comes to good medical care/recommendations. Best wishes.
