As some of you may have seen I wrote about the rarely seen Bagel Implants back in the fall( I wrote an original post then an update). I have now found some more information on this type of implant which is actually better known as a Saline Injection.
A Saline Injection is a saline solution being used to inflate a body part. Such as, in the case of the bagel head implant, the forehead. While doing a quick internet search I also found that some people use saline implants as an alternative to silicone for breast augmentation.
The solution used is sterile .9% salt water and takes up to a few days to absorb into the body and deflate. So it is not a permanent body modification, making it a little like play piercings. There are risks involved with this such as stretched skin, discoloration of the area, and in some cases gangrenous growths which must be amputated.
