Retainers are usually made from surgical grade polycarbonate or bioflex as they are flexible and translucent so they are less obvious when being worn. Mainly used to keep the piercing hole open when jewellery is not appropriate. These are a good alternative for a pregnant navel although it is not recommended to pierce women whilst they are pregnant.
A relatively new style of piercing is using a dermal anchor. Dermal piercing is essentially a surface piercing procedure where an incision is made in the skin with a needle or small dermal punch and a dermal anchor is inserted. This style allows the look/style of a piercing without an entry & exit point as a traditional piercing.
Stretching is generally performed in the ear lobe. This is done using tapers where the ear is pierced and once healed a taper is inserted to stretch the hole. Generally one gauge at a time until the desired size is achieved. Stretching is generally achieved one gauge at a time. The taper is inserted into the piercing breaking the tissue but not making the piercing bleed. When the tissue is healed the taper is inserted another gauge size, again breaking the tissue. When the issue is healed the process is repeated until the desired hole size is achieved.
