Chances of Side Effect from Silicone Lip Injections?

Silicone complications are real and are the result of contaminants in the silicone than can stimulate an inflammatory response. I would stay clear of silicone injections in the face.

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 initial medical use was only for retine problems.  
Any type of silicone injections are very dangerous for your body. It doesn´t matter if it is dense or less dense, if it has more weight or less molecular weight, if you recognized the brand or not, the problem is that the immune system reacts against them and produces inflammations and degeneration of the tissues, then the recommendation is not to inject it never. If you search in the Internet you will find positive comments, but also search negative comments from people who had complications with this product, because the reactions can ocur 60 years after its application. The Biopolymers cause a severe inflammatory reaction, known as Iatrogenic Allogenosis and Autoimmune Syndrome (A.S.I.A. Syndrome), then the use of any substance that is permanent is not advised, it also could migrate at the initial injection suddenly, via retrograde arterial flow, at blood stream to organs and even to the lungs; that would be a catastrofic event. So, if you want to increase your lips, you have to use safe substances that are resorbable like hyaluronic acid; there are brands like Juvederm and Restylane that are qualified, 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.

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.
