My daughter needs a QUICK fix of home remedies for her skin!

My daughter suffers from acne. It started for her at the age of 11. Her face has serious acne. We have tried many things, Proactiv, Neutrogena, and prescriptions, and gel. She has a big Christmas Eve party tomorrow, and these products are more long term types for her face. Her acne gets so bad that she sometimes can’t even go out in public (Christmas Eve party), WE need a fast acting “cure”, or something just enough to get those pimples a little smaller. Also, we don’t have a lot of time, so something fast, and possibly a home remedy would be super helpful. Thanks so much!
