When a product is used in a way outside of the one for which it was FDA approved, it’s called off-label use. Assuming that you are seeing a reputable plastic surgeon, this does not mean that it is unsafe. It just takes a long time for things to go through the FDA approval process. In fact, Botox was only recently FDA approved for use on the forehead yet plastic surgeons have been using it safely there for years. But it is always important to speak with your surgeon about the appropriateness of the off-label use of any product.
