Is ThermiTight or SkinTyte preferred among Doctors for tightening a neckline with only skin laxity issues?

ThermiTight is my
favored choice when treating the neck for a nonsurgical lift. I
haven't had any experience with SkinTyte, but have not been impressed
with the results I've seen in other practices.

There
are several other options for tightening the neck as well. In our
practice, we also have other radiofrequency devices such as Thermage
and Infini (RF with microneedling for crepey skin of the neck) and
microfocused ultrasound.
Another
option I’m excited about is the Silhouette Instalift. These are
absorbable sutures that were initially used only in the face, but now
can be placed along the jawline and upper neck to get both an
immediately visual result and a result that improves over time.
Because they are made of a material like Sculptra, the body produces
more collagen in response to the sutures

Rather than trying
to settle on the technique you want to use ahead of time, your
research would be better directed to finding a board-certified
dermatologists in your area who have proven expertise in tightening
the neck without surgery. The skilled practitioner with a strong
sense of aesthetics will be able to choose the right technique for
you and – more important – wield it expertly to get the results
you want.
That
said, a combination treatment sounds perfect for you. First,
ThermiTight is a minimally invasive technique that uses a small probe
to deliver pulses of radiofrequency energy to the skin's collagen
layer, forcing it to heat up, contract and tighten. The insertion
points are very small -- about the size of a regular injection –
and therefore heal without any kind of scar. If you have any excess
fat, combining ThermiTight with liposuction can create a dramatic
improvement. Secondly, if needed, Instalift sutures along the jawline
and upper neck could give that extra upward vector to your neck and
create a true lift. Please find a board-certified dermatologist who
has expertise in using ThermiTight to create a nonsurgical neck lift.

I personally prefer ThermiTight - this is the treatment I have used on many patients in my practice with great success. ThermiTight delivers radiofrequency energy deep into the dermal layers via tiny electrodes, where the gentle heating will have the greatest effect. Keep in mind that any procedure will only be as good as the experience and expertise of the doctor performing it. Make sure you choose a board-certified dermatologist with extensive experience and training to ensure an optimal outcome. 

Lifting of the skin often requires surgery but if that is not an option there are many others to consider such as botox, radiofrequency (venus, velashape, thermage, thermi), ultrasound (ultherapy).  I suggest seeing an expert.  I inject sculptra in all my face/neck lifting patients.  Best, Dr. Emer.
