Eurosilicone implants are manufactured in France but not sold in the United States as they are not FDA approved. The procedure is done by placing implants behind breast tissue or under the chest muscle. The silicone implants are made with cohesive silicone gel and include a barrier layer called Paragel that keeps the gel in place. The implants come in round or anatomical shapes in a variety of sizes, profiles, textures and densities. The textured layer or shell is designed to lessen the risk of capsular contraction. After the implant is placed, the incision is closed. The gel will not migrate in the event of the implant rupturing.
