Once you get a pimple whats the best way to get rid of it quickly after you pop it and it swells up?

i already know theres no cure for acne i just want to know what to do once you get a zit and dont tell me not to pop it cuz im not walking around with a big ol white headed thing on my neck|||i love using the toothpaste thing right before bed it works say you have a really sore one the night b4 it will be much better the next day
