Are Saline and Silicone's Implants Shells the Same Thing?

The outer walls of the silicone and saline implants are both made from a silicone elastomer. The structures and composition are slightly different but they are essentially the same.

Each manufacturer makes the shells for their implants, whether saline or silicone.  Obviously the saline implant has a valve in it also.  That is the only difference.

An experienced surgeon can recommend what is most attractive and best for you. But yes, the implant shells are the same in both saline and new silicone implants.
