You can use it for any duration at least 60 minutes in your discretion.

The longer you wear it, the better is the effect, as long as it does not interfere with blood circulation because persistent use is the essential condition for correcting the facial contour (Whenever you feel tightness from extended use, lift the p-plate a few tomes slightly using both hands).

HEADrang is not a type of products that create effect in a short time, so wear it for at least 60 minutes applying appropriate pressure to reduce the size of facial bones, change the facial contour to V-line like celebrities, to reduce the size of buccinator (cheek muscle) and masseter (muscles between cheekbone to lower jaw), and to improve asymmetry.

 ※Caution: Using it in wrong method or too strong intensity may interfere with blood circulation and cause pain, so refrain from extended use in that manner.

We recommend adjusting to appropriate intensity you feel comfortable and suitable.
