Well, we all hear that a lot in the media. Women of all ages now are talking about breast implants. Girls as young as 18 are considering getting breast implants. But what is it exactly? If you know how it’s done, you probably will think twice about getting one. Keep in mind, breast implants are medical devices. They are not manicure or pedicure. The surgeon implants a special material either under your breast tissue or under the chest muscle for breast augmentation or reconstruction.
There are mainly two major types: saline-filled and silicone gel-filled. You might hear or read somewhere that new stuff is coming to the market. Be aware of these commercials. Because there are only two kinds of materials that are approved by the FDA: saline-filled and silicone gel-filled.
Saline-filled breast implants are silicone shells that are either pre-filled or filled with saline during surgery, and some of these allow for adjustments of the filler volume after surgery. Silicone gel-filled breast implants are silicone shells pre-filled with silicone gel. Breast implants vary in profile, size, and shell surface. You might wonder that shell surface is. It means smooth or textured surface. No one knows how would anyone prefer textured surface. But that what it is.
