You can aim the iTeracare at your entire body, but keep in mind the heat.
There are 3 modes:
Use one layer for your face and eyes or where your skin is thinnest. High for the areas where the skin is thickest such as the soles of your feet and your palms and medium for all other places on your body.
Never blow in the same place but move, up and down, from left to right and vice versa and make spiral movements.
Make it feel good … bearable!
