I've has my belly button peirced from september-december last year , there is still a keloid there its not big at all , I'm wondering if I use tea tree oil will it still work on my keloid after it's been there for several months ?

If, by chance, the tea tree oil doesn't help, I suggest crushing an aspirin and adding a drop or two of water to make a paste. Keep the paste on for about 15 minutes. Do this daily for around two weeks. The aspirin paste will act as a very mild acid that will eliminate the keloid. No pain involved, either. We recommend both remedies (tea tree oil and aspirin paste) and have yet to have bad results.
