I had silcone implants put in under the muscle is gives you the most natural look, and feel more natural. In the doctor's office I held both a silicon and a salline implant and there is a huge difference. The saline is alot more liqiud feeling, it kinda sloshed around in my hand. Also, the gel is totally safe these days, even if there is a tear in the implant. My doctor had actually cut a gel implant in half, and the gel is in such a state that it didnt fall or leak out of the inplant, it was still in place, it was kinda weird, but totally put my mind at ease.
