there are no treatments similar to botox that last longer. botox does work very well in the right candidate to smooth neck bands but not for excess skin. there are new radiofrequency and less invasive liposuction-like devices that are coming in the next year or so that may work well for "turkey necks" but nothing beyond liposuction and plastic surgery for now.
are there new treatments for turkey necks? botox is expensive. are there any treatments that last for a year or more?
