I was curious if anyone knows so acne cures that work very fast, and can be homemade?

There aren't any. The over-the-counter product that works best is benzoyl peroxide. None of the home remedies you'll find online (lemon juice, sleeping with your face smeared with honey) will work, and I suspect some of them are cruel pranks on folks with an already-cruel disease. And no rx of any kind words very fast. Please get with a scientific physician. He/she can help.
