how to reduce hickeys?

what’s a good way to reduce hickeys fast, or get rid of them totally? anything that you’ve done and it actually worked would be super helpful. i don’t wanna try a bunch of stuff and them not work. and i’m not looking for the smart comments saying “just don’t get one” well duh but, stuff happens. i just need advice. it’s on my boob and i read online that toothpaste soothes and reduces them which makes sense since it makes my pimples disappear. any other tips incase this doesn’t work would be great though, thanks (:
