What is the Life Expectancy for Bio-gel Buttock Injections?

Hello Millisecond, I’m deeply sorry for the health problems you are experimenting. Serious complications after getting Biogel injections may occur right away or could develop weeks, months, or even years later. I recommend setting up an in-person consultation with an experienced plastic surgeon for evaluation and possible removal of the Biogel injected into your buttocks.  An Magnetic Resonance Imaging (MRI) scan may be necessary to evaluate the location of the injected material. The treatment varies from patient to patient, since no two cases are exactly the same. This may range from surgical excision, to hyaluronidase injection followed by VASER Liposuction and fat transfer into the area to correct the resultant deformity. Moreover, I strongly suggest you seeking medical attention immediately if you experience problems such as difficulty breathing, chest pain, signs of a stroke (including sudden difficulty speaking, numbness or weakness in the face, arms, or legs, difficulty walking, face drooping, severe headache, dizziness, or confusion), as it may be a life-threatening situation. Good luck and may God bless you! Dr. De La Cruz.

Unfortunately, the big question is what were you really injected with. Many people who get Butt Injections are told they are being injected with one thing but often get injected with something else.  Hydrogels are very expensive.
If Hydrogel is really what you were injected with and you survived the procedure without dying from pulmonary embolus and survived the first few weeks without any infections, then you are lucky and it should be gone in about a year or two.  If in fact it was not hydrogel, and you were still lucky enough to have made it through, you may be perfectly fine forever, or you may develop painful lumps.  Hopefully you will not.  But if it is silicone which seems to be the most commonly injected substance, then it is permanent.  You may have problems, you may not.  There is no way to know.
