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. Unfortunately doesn´t exist non-surgical treatment for granulomas caused by biopolymers; chemotherapy, anti-inflammatory, and other ways has been tried but they haven´t work. After it is possible that the same medications do work. So, the best solution is to remove the product as much as possible, but remember that you can never remove it completely, it is not possible. 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 Rios.
