Is non-surgical BBL available in the US?

Due to the excessive cost of the FDA registration process which can run into the tens or even the hundreds of millions of dollars, Brazilian tissue filler manufacturers cannot afford to enter the American market, and that is basically why there isn’t a legally approved gluteal filler in the United States. American doctors use facial products such as Sculptra or Artefill and inject them off-label into buttocks leading to failures and high frustration in patients as facial fillers lack the necessary consistency and lifespan.
