Dr. Driscoll, www.beverlycosmeticsurgery.com, has done a lot of UK patients. I saw a BBC documentary about him and breast implants, but I know he is the only one in Texas doing butt implants for the past 10 years!! I would give him a try.
NO! Not safe. The FDA did not approve the silicon gel implants b/c they have a very high rupture rate when sitting on them. Stay away from them!!
