Silicone Injections in Lips/now Juvederm XC and 9 Days out Tingling Still?

Our office spec ializes in the treatment of silicone
injections to the buttocks, face, and soft tissue. Liquid silicone in primarily
used to enhance soft tissue volume and patients gravitate towards the filler
because of its permanence.We see patients
from across the country who have complications arising from silicone injections
to soft tissue.The silicone, depending on
the amount of contaminants contained in the injection, can cause a severe
inflammatory reaction that can cause permanent changes to the skin, leading to
pain, itching, burning, ulcers, fibrosis, and swelling, among other problems.
In our plastic surgery office, we have employed conservative as well as
surgical protocols to help patients deal with the permanent deformities
stemming from PMMA, biogel, biopolymer, biopolimera, artefill, artecoll, and
other injections. The first stage in improving your condition would be to
schedule a consultation to discuss your options after a complete examination is
made. We typically advise against adding more fillers if there is inflammation within the soft tissue. Raffy Karamanoukian MD FACS

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 inical use is for retine problems. 
Biopolymers are unrelated to hyaluronic acid. I could not afirm that hyaluronic acid mixed with biopolymers caused any damage. Anyway, I would need a photo of your lips to give you a better diagnosis.
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.

There shouldn't be any problem having Juvederm injected into an area (this case the lip) where silicone was previously injected. The tingling and pain has nothing to do with that, but it is likely related to your recent Juvederm treatment. I suggest you follow up with your injector if it persists.
