How can SculpSure target only fat cells without harming other cells such as internal organs?

sculpsure just like coolsculpting an vanquish only target fat cells due to their absoption profiles. There is nothing to worry about internally.  Best, Dr. Emer.

SculpSure uses a diode laser which generate optical radiation (1060 nm) that specifically targets the subcutaneous adipocytes (fat cells).  It penetrates less than 1 cm beneath your skin and not deep enough to reach any internal organs. 

Regarding your pain... we have treated many patients (including myself) and it definitely should not be painful.  Everyone has different tolerance to heat that's why this device has different energy setting to adjust (from 0.9 to 1.4 W/cm2), with the default setting at 1.1.  Furthermore, there are 4 applicators per treatment and the energy level can actually be adjusted individually to further customized to each specific area.  One thing is that your practitioner has to "un-link" before the treatment started, otherwise, all the 4 applicators would have to be adjusted together (as with the current firmware).  

If adjusting to the lowest setting is still not comfortable enough for you, you can ask him/her to press the "advance-to-cool" button, which will then cool you down immediately and last for 40 secs. I used this function twice and both my patients tolerated well and finished the treatment successfully.  

Hope this helps!
