Kybella can be used safely after a prior facelift, necklift, or even submental liposuction procedure. It is important to make sure that your physician is aware of these prior procedures on your neck, which they should be asking about at length anyway. Timing after your prior procedure is important, and I would make sure that you wait until your previous procedure is completely healed and settled before considering injections. To ensure you are receiving the highest level of care, seek out a dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these "core four" cosmetic specialties.
