No and it is dangerous too

Injection of any material that is not biodegradable is not a good idea. PMMA has been used for the reconstruction of the skull with mixed results, but when injected into soft tissue ,it will cause reaction. I have seen patients traveling to Europe for these injections and having very bad result. The sad thing is that we can help these patients since the injected material is not in one spot and it is impossible to remove it. Please look into fat grafting if you like to have butt enlargement
