Can you please list the most common home remedies for getting rid of or preventing pimples?

They don't work: Acne is a serious, chronic, non-lifestyle-related, non-hygiene-related disease that presents a major social problem and is often permanently disfiguring.

If topical benzoyl peroxide has not cleared it up after two weeks, get with a scientific physican who knows what they're doing. Do the right thing.
