SILICONE IMPLANTS ARE DESIGNED NOT TO LEAK. Dr. Gabbay cut a silicone breast implant to demonstrate how resistant silicone is from leaking out of the implant. The modern, fourth generation, silicone implant has many design features that prevent the silicone gel from leaking out. The shell is quite thick and strong, resisting tearing. Also, the silicone gel inside is very cohesive – meaning it sticks together. The gel does not leak out, even if it is squeezed.
