Buttocks implants worried?
In my experience once someone has gotten through the first 6 months of healing from a procedure you shouldn't have issues later on. Of course you should do your research on a surgeon. Be sure to go to a surgeon who specializes in buttock implants and has extensive experience in doing this procedure. Pictures are important as well. If the surgeon does this procedure regularly, everything will be ok. Enjoy!
