What is the difference between the ProFound and ThermiTight?

There is quite a large difference. The ThermiTite is
Radiofrequency through a small probe that is inserted under the skin, mainly in
the jaw line, to melt fat, and tighten the jawline and chin. The newest device,
that has taken over this market is the FaceTite or NeckTite.  On the majority of patients, fat is suctioned
from the chin and jowls if needed. I have done many treatments with the
ThermiTite, but I have now upgraded to this new device, the FaceTite.
The ProFractional  a
stamping treatment performed by a handpiece with a series of needles with heat
at the tips. This can be done with topical Lidocaine alone, and is often
performed by a nurse or aesthetician. The entire, face neck and chest can be
treated to improve texture, tone and tightening of the skin can be achieved.
Fat is not removed.
The ThermiTite is mainly used on the chin and jawline, and may
produce a better result than Profractional alone in this area,  with only one treatment needed. The other
areas of the face, neck and chest can be treated with a series of 3 treatments
using ProFractional. Also, ThermiTite can be performed first and then
ProFractional over the area in the same treatment, to treat more externally the
skin texture.  Which you chose depends on
your goal. If you pick an experienced physician, they should be able to chose
the best device to achieve your goals.
