A navel piercing is a type of piercing located through, in, or around, the navel. It may heal quickly and with no irritations, like an ear piercing, or may heal more like a surface piercing with the associated extended healing time. Healing usually takes around 6-9 months, or even more and as long as it is cleaned, it will heal nicely. Unlike most surface piercings, this is one of the few that do not normally reject, although the rejection rate is higher than non-surface piercings, such as ear piercing. The actual navel can only be pierced if it is an outie. For innies, the skin surrounding the navel is pierced at one or more locations. The most common form of navel piercing is through the upper rim of the navel. It is commonly a female piercing, although not exclusively.
