HEADrang is the product to induce a gradual improvement of the facial skeleton using the principle of flexibility of bones.
Therefore, it does not stimulate facial skeleton excessively. So, it does not cause pain if you employ a proper use of HEADrang with correct chin band adjustment.
However, if you wear it with the chin band too tight, or wear it in improper way, then the pain may be caused.
You may feel a little bit of tightness after wearing HEADrang until you are adapted to it. It will gradually improve if you briefly lift both the P-plates a little whenever you feel the tightness. If the facial pain or headache continues, however, use the HEADrang with the chin band released.
If the same phenomenon occurs even with the chin band off, reduce the wearing duration of HEADrang, and gradually increase the duration again according to the progress.
You will be able to wear it without causing pain with appropriate band tension and duration adjustment that you feel comfortable because the facial structures vary in every person.
※ Use the intensity that you feel a little tight because the applying pressure is the essential part for the correction.
