The Recovery Piercing Aftercare Tea Tree Oil is a natural way to help treat and heal all kinds of ear and body piercings. This premium tea tree oil is a product of Australia and comes from the Australian melaleuca tree. It can be applied directly to an infected area as a standalone treatment, but adding a few drops to a saline solution is usually the best option. Sometimes abnormal bumps appear after a piercing (that does not mean it is a keloid cartilage bump though). Tea tree oil is an effective way to dehydrate and eliminate those bumps. Tea tree oil is a natural antiseptic and also moisturizes the skin which will help reduce any scarring and swelling.
