Do stretched earlobes ever completely heal up and stop smelling?

If you keep them clean, including cleaning your plugs; if you massaged them with oil. If you spent a bit of time each day without plugs in. If you used organic materials for your plugs, so your ears were able to 'breathe' a bit. These things help.

But the smell is due to sebum, dead skin cells that build up. If you wear plugs all the time, it'll build up and stink. So it's not that if you wash them steadily for X number of weeks, then stop, they won't smell - they will smell. You need to wash them daily, and etc.

What a lot of people do is take their plugs out every day when they shower and wash their ears at that time. Many say that the vitamin E oil helps with the smell as well.

I let mine grow over more than a year ago. Even though they're back to normal holes, I still massage them with oil and clean them everyday. They still stink.

Mine are healed entirely and they don't smell because I keep them clean.
