The short answer to your question is that Restylane can most certainly be injected throughout the neck. That having been said, without a photo and at least a bit of background information, I absolutely cannot say if that would be indicated or appropriate for you. I frequently perform The Nonsurgical 3D Vectoring Necklift for mild to moderate sagging of the neck, either as a stand-alone procedure or in concert with Botox for performing the Nefertiti lift to treat ropey cords in the neck, to pull up jowls along the jawline and to provide a sharper neck-chin angle. Juvederm Ultra Plus XC is my preferred volumizing filler in my Upper East Side Manhattan practice for the jawline region and for the neck itself. In my Israel satellite facility, where a far greater number of regulatory agency approved fillers and volumizers are available, I typically opt for Princess Volume and Stylage XXL for this purpose. The neck is not a region for treatment by novice injectors accustomed to chasing after smile lines with Restylane. It is a region where very advanced injection techniques are required. I would strongly urge you to seek consultation with a board certified aesthetic physician with experience and expertise in the nonsurgical use of fillers and volumizing fillers for neck rejuvenation. And before proceeding, make sure to ask to see his/her before and after photos.
