What is the safest way to close a new ear lob piercing?

Your best bet is to have it close up on its own. It may only take a few days to close since its fairly new . Dont have any surgery to fix it .

I would remove your earrings right away.  Often if this is done early on, then the hole will seal on its own.  Otherwise, you may need to re-excise the hole at a later date and repair it.
