Which acne home remedies are considered effective?

Benzoyl peroxide: This is the best over-the-counter rx. The "pop" remedies (squeezing lemon, sleeping with your body plastered with honey) are unworthy of anyone living in the 21st century. Scientific medicine can clear all acne. If someone for whom you are responsible has acne, get them treated now, or it will be the source of a lifetime of regret.
