Radiofrequency and Fat In the Neck, It will Not Affect it If you use the right device
RF on the neck is amazing but you want superficial RF for crepe skin and deep RF for tightening. I use sublative or viva for superficial tightening (crepe skin and texture) and thermage for deep lifting (and I never get any fat atrophy). It is not the device used it is the person doing it that matters most. Go to an well trained expert for treatment. Best, Dr. Emer.
