We hear about breast implants all the time. Women young and old are thinking about getting theirs done. But do you know all the details? Breast implants are medical procedures and they cannot be reversed. Like all plastic surgeries, breast implants are medical devices. They are implanted either under breast tissue or under the chest muscle for breast augmentation or reconstruction. Currently, there are two major types: saline-filled and silicone gel-filled on the market.
Saline-filled breast implants are basically silicone shells. The doctors use either refilled silicone shells or filled with saline during surgery. In most cases, these allow for adjustments of the filler volume even after the surgery. Silicone gel-filled breast implants are silicone shells prefilled with silicone gel. Whether you would use one or the other depends on your doctor or your preference.
You don’t usually think about it, but breast implants vary in profile, size, and shell surface. Which means the surface can be smooth or textured.
