Unlike most procedures, our guidelines for treating you aren't based on raw numbers but based on how YOU feel. As recommended by the developers, we score your discomfort like this:1: Pleasant cool/cold feeling2: Gentle warming and cooling3: Tingly, short intervals of warmth and cooling4: Longer peaks of moderate deep warmth andcoolingWe want you to be in the 3-4 range for fat destruction. Some people say they have a feeling of cramping or discomfort, and it it's not too bad, that's ok. Pain beyond a number 4 can make you more likely to have side effects and is not necessary for it to work. Thinner people and areas with less fat (like the upper arms or inner thighs compared to the abdomen) tend to need lower energy.
