Is ThermiTight or Smartlipo best for small double chin?

There are many variations in neck structure. There are variables in the amount of muscle band sagging, loose skin, and fat compartments from patient to patient, and that is why I must analyze each patient that sees me in consultation as an individual and customize a plan to improve their neck. In contrast to what has been incorrectly posted below, Thermi Tight does reduce fat if the physician chooses to do so. Certainly it is designed to also tighten the dermis, but as the internal set temp is elevated for fat reduction, I can reduce considerable fatty necks. Double chins are also treated effectively with the new CoolSculpting Mini as it freezes and kills the fat cells, and Kybella injections can dissolve the fat.  Liposuction, can remove the fat, and laser-assisted liposuction, such as Smart Lipo can help tighten the dermis.Botox injections can help reduce the muscle bands but if there is considerable hanging of muscle bands, nothing can provide as a good a lift as a surgical neck lift.The information provided in Dr. Shelton's

Thank you for your question.If you are looking minimally invasive or non-surgical options, I
am finding that the combination of Kybella or Coolsculpting Mini to reduce the sub mental
fullness and an energy device to tighten the skin are among the best
non-surgical combinations to help your neck concerns.Kybella is an
injection procedure that dissolves the fat an may require between 2-4
treatments spaced 4-6 weeks apart. There is some swelling and bruising
potential, with the greatest amount with the first treatment.The
Coolsculpting mini procedure cools the fatty tissue under the submental
area and also reduces the fatty tissue under the chin.As far
as energy devices, I would recommend Ulthera if you are looking for
something with no downtime, or Profound if you could tolerate some
downtime. Ulthera is an ultrasound based energy that heats the
underlying tissue and stimulates collagen in response. Profound is a
radio frequency microneedling device that allows for the creation of
Elastin, collagen and hyaluronic acid and hence restores some of the
lost elasticity in the neck. It has more visible downtime with the
possibility of some swelling and bruising that diminishes in about a
weeks time.Surgical options are also very rewarding and include
liposuction or neck lift. I would recommend visiting with a board
certified plastic surgeon in your area to help you discuss your options
in more detail.

I treat this everyday in my practice. You may be a surgical candidate but you do not need surgery for improvement. Properly performed liposuction with energy based devices (sometimes one, sometimes in combination and this is decided in a consultation) and physical fat removal will do fantastic to remove the fat, lift the skin, and contour the jawline. I pretreat everyone with Botox 1-2 weeks before surgery to relax the neck muscles, allowing for better retraction of the skin after surgery. Then after treatment we do skin tightening with Venus Legacy to improve the results and decrease the neck swelling. I suggest you only see an expert for treatment of this area as a meticulous surgeon is required to get great results and complications in this area can be devastating both medically and cosmetically. A new medication that is used to remove chin fat with injections called Kybella may also be an option, as it secondarily allows for skin tightening/lifting as well. A formal consultation is needed to determine what are the best options for you. Best, Dr. Emer. 

ThermiTight is a great minimally invasive procedure to treat
skin laxity. ThermiTight delivers radio frequency energy subcutaneously to
tighten the skin in the desired area. This is different than laser energy which
is used in the SmartLipo procedure. SmartLipo would remove the fatty tissue and
address skin laxity with the laser however not to the degree of ThermiTight.
Some patients may elect to have these two procedures performed inconjunction
with one another for optimal results. . ThermiRF offers you a superior choice
when you’re looking to tighten any areas of your skin. It also offers the
following benefits:

FDA-approved

Minimally-invasive

Minimal
downtime

Improves
skin’s appearance

Increases
collagen production

Works
quickly and can slow and reverse aging signs in just a few short weeks



I recommend consulting with a qualified physician for a full
consultation

If you have a small fat pocket that is contributing to your double chin, then lipo would be the best option for you. ThermiTight only addresses excess skin and not the fat component. At age 34 you probably still have good skin tone and have less a need for skin tightening. 

Both procedures will do well but ThermiTight is less invasive. Also, consider Coolsculpting with the CoolMini applicator. It was just FDA approved and is completely noninvasive. Results occur as early as 1 month but typically 3-4 months after treatment. Of course, seeing before photos will help guide you towards making the best decision. Get a few consultations with providers that are skilled in several modalities. Hope this helps!

Both would improve your condition although neither might "prevent" the family turkey neck.  Without pictures or even better, a direct consult it is impossible to say which might be better.  ThermiTight removes fat by coagulation and then tightens collagen by shrinking it (both shallow  and deeper). Smart lipo suctions fat and heats the tissue with laser energy.  There are other treatment modalities that would work.  Keep that there are causes in adiition to fat and loose skin that cause turkey neck and other ways of treatment.  You should  consult with a surgeon that has many treatment options including surgery to determine what would be your best choice.

This condition is usually due to lipodystrophy or abnormal fat deposit in a well defined area. ThermTight may be appropriate for skin tightening but not for fat reduction. Smartlipo is slightly more invasive but its designed to accomplish LaserLipolysis and thermal coagulation which will permanently destroy targeted fat cells as well as stimulate collagen production and skin tightening.There is now also a third option for treatment of double chin, KYBELLA, which is essentially mesotherapy technique for localized fat reduction (double chin). In the near future, Ulthera is also introducing a new transducer specifically for tightening of the under skin area. All of these options have their own advantages and disadvantages. I would suggest consulting with a physician who offers all these options to illuminate the retail bias from the equation.
