How to deflate the Oaks Gua Sha Device and Cupping Device:
1. Make sure your Oaks Gua Sha Device or Cupping Device is in close contact with the skin surface. Make sure there are no leaks.
2. Use your fingers to gently press the raised air valve button on the Oaks Gua Sha instrument or cupping device. This air valve button is usually located on the top or side of the gua sha or cupping device.
3. Slowly release the pressure and gradually release the air. You will hear a small "hissing" sound, which means air is being released from the Oaks Gua Sha Device or Cupping Device.
4. During the deflation process, you can adjust the strength and time of pressing the air valve button as needed. Make sure you deflate at a moderate pace to avoid skin discomfort caused by a sudden release of large amounts of air.
