Streching of piercings
If you speak about to stretch a piercing so you guess the enlargement of the respective canaliculus, to apply piercing jewellery with a bigger diameter.
Most often it happens by the lobe piercing in the earlobe. Principally also other piecings can be stretched, certainly thereby some difficulties on scattered body locations could appear (e.g. by cartilage- or surfacepiercings).
It´s important that the stretching of piercings is a permanent change, which can´t be reversed on its own in most instances. Often it´s expanding of only optical effects, but there are also piercings, whose the expanding is recommend to get a better wear comfort and to prevent the avulsion.
