Most body-piercings can be hidden through the use of retainers. Retainers are a type of body jewelry that are clear in color and come in varying gauges and shapes. There are straight retainers for tongue piercings, curved for navel piercings and Labret, or Monroe retainers for lip piercings. Retainers are usually made of a flexible silicone and are secured in place by small clear 0-rings. There are even small clear and flesh-colored retainers available for nose piercings. When looking to purchase a retainer, make sure it is the style and gauge you need and remember, it does not render your piercing invisible, it just makes your piercing less obvious.
