Saline breast implants are a type of breast implant that is made from silicone shells filled with sterile salt water. The saline solution inside the implant serves as a filler and provides a more natural feel than silicone gel in other implant designs. Saline implants do not have any significant health risks and they typically last between 10 to 20 years.
Silicone breast implants contain a silicone gel that feels more similar to natural breast tissue. With silicone implants, you will need to visit your plastic surgeon regularly so they can assess their condition. Leaks are rare, but do run some risks.
