If your jawline has blurred,
we check whether it is sagging or firmness.
A bipolar RF lifting device. For sagging we use FX, which draws the skin up by suction; for skin tightening we use Forma, which warms while watching the temperature.
The short answer
If sagging is the concern we use FX; if skin tightening is the concern we use Forma.
When both overlap, there is also a package that runs FX and Forma over the whole face. Which one weighs more is decided at the exam.
RF
RF energy runs between two electrodes to create heat.
FX
RF energy is delivered while the skin is drawn up by vacuum.
Forma
It warms the skin evenly to a target temperature while watching the temperature.
1Area
One of the jawline, the double chin, or the deep cheek.

How we decide
A blurred jawline usually has two kinds of reasons: sagging and loss of firmness. Which one it is changes the handpiece we use.
When the jawline and under the chin have dropped and the contour has blurred
When the skin has loosened and the contour is not sharp
When both overlap, the exam shows which one weighs more.
STEP 1 · Assessment
A jawline blurred by dropping and a jawline loosened by a loss of firmness are read differently. The two can also overlap. If something other than InMode fits better, we say so.
RF energy is delivered while the skin is drawn up by vacuum.
It warms the skin evenly to a target temperature while watching the temperature.
How they work is based on the manufacturer information.
STEP 2 · Planning
We use FX where sagging is greater and Forma where the skin needs tightening. Sometimes both, sometimes only one.
This is a sample form. It is not a real patient record or treatment outcome, and the items can change with the exam.
STEP 3 · Record
We note which handpiece was used at which settings and how swelling and response went. The next session is set from that record.
If the change you expect does not match how this device works, we tell you right there.
Ask about your concernHandpieces
Even with the same RF, each handpiece does a different job.
FX
RF energy is delivered while the skin is held by suction. One area means the jawline, the double chin, or the deep cheek.
Forma
It warms evenly while watching the skin temperature. Used when looking at firmness over a wide area.
They are different handpieces that attach to the same InMode device. The names are easy to mix up, but they work differently. Which one we use is decided at the exam.
Who it fits
For a jawline concern, the device we look at first changes with the cause and the depth.
The final device and treatment area are decided after an in-person exam.

FAQ
