Dangers of Using Silicone Oil As Facial Filler?

Silicone is manufactured in a number of viscosities and has been advocated for medical use due to its hydrophobic and theoretically inert properties. Medical grade silicone has been used for decades as a permanent tissue filler for the lips and soft tissues of the face. In fact, decades ago, silicone injections were used in the breasts and buttocks.

The dangers of silicone injectables arise from their unpredictable safety profiles. The rate of silicone induced inflammation and tissue reaction is highly variable and may pose a significant risk of deformity and nodularity in the future. Since the injectate is diffusely involved in the tissue, it is difficult to remove if medically indicated.

I regularly consult on patients who have successfully undergone silicone fillers in other countries. Many of these patients are happy but an unfortunate percentage of these patients are extremely disfigured and deformed as a direct result of the silicone. Thus, the risk is far too great to advocate in an elective procedure.

The face will lose soft tissue as we get older. That is why plastic surgeons are now placing fillers, (Juvederm, Restylane, Sculptra, Radiesse), in the face. Some will last a relatively long time.
The idea of silicone in the face is not a new one. In the past, it has been the cause of problems later on. Silicone can move, and the facial tissues may change over time, but he silicone does not necessarily move with it.
For all of those reasons, few plastic surgeons have embraced this technique. Better to have something that will fade away when it comes to the face.
BTW, It is illegal to inject silicone in Nevada.
Hope this helps.

Regards, 
Liquid silicone is unsafe, please do not use it ever. The autoimmune response could be triggered by this substance, if you look around on the Internet, you will find patients that have a lot of problems with this product. The use for lips and other areas is off label. The inicial use is for retine problems. 
The Biopolymers cause a severe inflammatory reaction that can cause permanent damage to the tissues, known as Iatrogenic Allogenosis and an Autoimmune Syndrome (A.S.I.A. Syndrome). The risk of having autoimmune diseases and deformities due to tissue damage is very high, then the use of any substance that is permanent is not advised, it also could migrate at the inicial injection suddenly, via retrograde arterial flow, at blood stream, that would be a catastrofic event. If dont, it could migrate to aroud tissuses. So, you have to use safe substances that are resorbable like hyaluronic acid, there are brands like Juvederm and Restylane that are safe, within the Juvederm family, it exists Juvederm Voluma, that has a durability of 2 years approximately.

Please remember to be aware, do not let any permanenrt filler to be injected into your face, breast, buttocks, calfs, genitalia, etc. The safest way to increase buttocks is through your own fat injections or through silicone implants.
I hope the information was usefull, have a nice day! Dr Carlos Alberto Ríos.
