What is a Surface Piercing or Surface Piercing Jewelry?
A Surface Piercing is where the entrance and exit holes are (usually) pierced through the same flat area of skin. Most surface piercings will fail due to a Piercer not being experienced with Surface Piercings, and not having full knowledge of how the body heals.
This piercing takes a lot of skill and experience to do correctly. I would recommend looking at photos of surface piercings that the Piercer has done that have healed to verify their experience, and not just go by what they say.
Some of the more common surface piercings that are done are the Madison, Nape piercings, Chest, Cleavage, and several piercings around the belly area. These places have very little skin to spare so they are constantly getting friction, which is what usually causes the piercing rejection.
The body Jewelry that is used for these piercings are specifically made for surface piercings and many times are custom made for the person or the Piercer. It is also recommended that you use the flexible jewelry such as for pregnancy which would be even better because it would move with your body and help prevent piercing rejection.
