Is there a way to get rid of acne very fast?

No: Acne is a chronic, incurable disease that eventually remits. If you need to clear yourself before the prom, a physician's prescription for a tetracycline, plus topical Clindamycin and topical benzoyl peroxide (never use just antibiotic) should work within two weeks. Now, even in our era of quick-fixes, you need to manage your acne day-to-day until it remits as you age. Best wishes.
