Is Liquid Silicone Safe?

Silicone is not currently approved for cosmetic facial augmentation. Silicone is theoretically inert but I routinely see patients from all over the world who suffer from inflammatory side effects resulting from silicone injections. Silicone injections can cause nodularity and deformity resulting from inflammation, granuloma formation, soft tissue atrophy, and volume deformity.

Regards, 
Liquid silicone is unsafe, it´s banned in many countries, 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 inical use is for retine problems. If you read about liquid silicone for retina problems, it has FDA approval, but the doctors or another "no specialists" make off label use and apply the substance in huge quantities, which is very dangerous for the patient. They even use it in other areas.
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.

Silicone injections in various parts of the body has been done quite frequently all over the country.  The difficulty with silicone injections begins with the quality of the silicone itself.  I have seen many cases where industrial grade silicone has been injected inside the human body.  This can be a tremendous disaster.  Problems can include infections, granulomas, cellulitis, and persistent skin infections, disfigurement and skin dimpling.  It is very easy to have silicone injected, but very difficult to have it removed.  The removal can frequently be very complex and involved lengthy surgery. Multiple operation is not uncommon.   It is not uncommon to expect scars in locations that would otherwise be undesirable.  If you do have silicone, or are having problem with silicone that was injected by a non-healthcare provider then you should certainly seek medical attention.  Some solutions include IV antibiotics, oral antibiotics and surgery after the inflammation has subsided.  Removing the silicone is not just a cosmetic issue but also an issue of better health.  Depending on the type of silicone injected concerns with autoimmune diseases and infections are foremost.  Taking medications such as ibuprofen or cortisone is only a temporary measure.  The real solution is surgery.  Not all plastic surgeons are willing to operate on patients who have had silicone injected in their body.  Many of these cases are not covered by insurance because they were performed for cosmetic reasons.  My recommendation to anyone that has had silicone injections and wishes to have it removed, is to seek a board certified plastic surgeon who is likely willing to do more than 1 operation as well as willing to do some of these operations in a hospital setting. I have had patients visit me for removal of silicone and the discussion to proceed is never an easy one.
