The best way to avoid infection with the helix piercing is to make sure the area is kept clean. You can ensure this by using a cotton bud and a saline solution and gently clean around the area daily.
It’s also important not to change or twist the piece of jewelry until you’re certain that the piercing has healed because this can cause an infection and prevent the healing process.
Interestingly, an infection may not be as a result of a poor piercee or lack of cleaning but it could be a result of the metal you’ve chosen to wear. Therefore, it’s important to do your research when buying your helix earring.
