Are There Breast Implants with Lighter Material out There?

Not currently

At the moment, only saline and silicone filled breast implants are available for the public in Canada. Fat transfer is also an option, although I don't approve it at the moment due to a higher rate of complications. There are no other alternatives.

Light weight implants

Per volume, silicone implants are lighter than saline. "Cream always rises to the top." Silicone implants have the consistency of fat and when scarring is minimal they feel very soft in the body. The are no other choices in USA.

Breast Implant Weight?

Currently the fill material of breast implants that are FDA approved is either silicone gel or saline. Similar size implants of either silicone gel or saline will weigh about the same, which is roughly equivalent to the weight of normal breast tissue. Obviously, the larger the implant the more it will weigh.

Saline and Silicone Gel Density as it Relates to Breast Implants

There are only two implant types that are currently FDA approved in the USA: saline and silicone gel. Both implants have a shell made from a silicone elastomer, but the characteristics of the shells differ slightly because of the requirements of each specific fill material.

The density of 0.9% saline used to fill the implants is ~1.005gr/cm3.
The density of the silicone used in breast implants is ~0.98gr/cm3.

A 300cc saline-filled implant weighs about 300gr
A 300cc silicone gel-filled implant weighs about 293gr.

As a comparison, the density of human fat is about 0.917gr/cm3.

A lighter implant would not feel as natural. The characteristics of the silicone gel approximate that of the human breast, and I believe the silicone implant has a softer (more gentle) interaction with the breast tissue as well.

Implant weight

There are only two types of implants available, saline and silicone gel.   Each weighs about the same.  A 454 cc implant weighs one pound.

Lighter Breast Implants?

The only available implants are made with a silicone shell and filled with either saline or silicone.  There is not a significant difference in weight between them.  Obviously, the larger the implant the more it will weigh.

Lighter breast implants for augmentation

The weight of a fuller breast implant can give some pause, however the implants, both saline and gel are the same weight, and weigh about the same as the natural breast tissue. A lighter implant might not be the solution to a natural feelilng breast.

Lighter breast implants

Silicone breast implants approximate real breast tissue in density and weight. Anything lighter would not feel natural.

Breast implants always about the same.

At the moment all breast implants weigh about the same. To fill substances are silicone and saline. They have approximately the same weight.
