When can you remove blackheads on the nose after a rhinoplasty?

There’s really no appropriate answer to your question.
A lot has to do with what was done during rhinoplasty surgery and where the skin lesion is located.
If skeletal structures are involved, you probably wanna leave things alone for at least three weeks.
It also depends on how much pressure you’re going to put on your skin.
Ask your provider.
