What should i do with this pimple?

Well its not really a pimple anymore. i was washing my face and then the pimple point thingy came off. now its just a red dot. It was bleeding too but my mom said that was normal. It got smaller and i think the pimple is dead. Do i just leave it like this or put something on it? if i do then what should i put on?|||air and time|||leave it alone
