Which is the most effective and fast product or way that get rid of pimples/zit/blemish?

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.
