What are breast implants made out of?

See below: A solid, thin silicone shell on the outside, filled with either saline or silicone gel on the inside. Good luck from NYC

Silicone elastomer: Implants currently are made of various elastomers of silicone.

A shell + a filler: Usually, the shell is a multiple layer silastic (silicone rubber), and the implants are filled either with silicone gel or saline. Different silicone gels exist, for different levels of softness or cohesivity.

Different types: good afternoon! In the United States, there are two types of breast implants. There are saline implants which are implants filled with saline or salt water- the same fluid you see in an IV bag. There are also silicone gel implants which are implants filled with silicone gel for a more natural feel. Both types of implant have an outer shell made of a silicone polymer.
