ALL initial piercing jewelry used in the studio is either internally threaded or threadless. Most manufacturers of this type of jewelry are focused on surface finish as well which is a paramount to healing, not to mention cute and shiny. :)
Most experienced piercers agree that piercings with internal or threadless jewelry heal faster, and with fewer complications.
Can piercings done with/containing externally threaded jewelry heal?
Yes, and sometimes without problem, BUT...
Poor finishing and external threads are reported to harbor more bacteria than high polish internal or threadless styles though so please be mindful when selecting the right jewelry for you.
