They are not in the category of dermal anchors, like you may have been misled to believe. They are also not piercings on the surface. As a matter of fact they are the typical piercings on the cartilage.
It is not a new concept or a new trend and has been around for quite a long time, but only recently have they come into the limelight. So if the person who is going to do it does not know exactly what a triple forward helix piercing is then you are better off not getting it done from him.
The next thing you have to remember is that when you have the triple forward helix piercing done, do not start with rings before the piercing is healed. This piece of advice is based on the fact that rings do have the tendency to move about and get snagged into hair, cloth etc and this can delay the healing process or cause more pain. Plus the chances of formation of scar tissue in excess also increases with the use of rings.
