All piercings require a sufficient “lip” or edge in order to be able to support the jewellery, otherwise this can cause the piercing to be too shallow and put too much pressure on the tissue, resulting in rejection or migration. Piercings like a helix, nostril or lip (where you can’t see the entry and exit points at the same time) are easy because they already have a clean lip or edge, however, piercings like a rook, navel or vertical labret require “grabbable” tissue. Surface and dermal piercings are usually pierced on a flat surface but still require pliable tissue for the jewellery to rest.
