Under or over the muscle silicone
Usually the deciding factor is how much natural tissue you have. If you don't have much tissue the edges of the implant can be felt and sometime even seen through the skin. Even with under the muscle, I can still feel the rippled edges of the implant at the bottom, though it's probably only noticable to me, hubby doesn't seem to notice it.
