Do you know which way is easiest and fastest to get rid of acne?

No quick fix: Acne is a non-curable, serious disease that needs to be managed until it remits on its own. Topical benzoyl peroxide as tolerated is your best friend. If this does not clear you, get with your personal physician. Forget about "home remedies" and don't try to understand why you're affected and others aren't -- it's not hygiene or lifestyle-related.
