It is generally not recommended to use a deep tissue massage gun on sensitive areas like the face or abdomen. The intense percussive action may be too aggressive for these delicate regions, risking injury or discomfort. Facial muscles and organs in the abdominal area require a gentler approach. If massage is desired in these areas, it is advisable to seek the expertise of a qualified massage therapist trained in specific techniques for sensitive regions. Using the massage gun on these areas without proper knowledge or caution may lead to unintended consequences. It's essential to prioritize safety and adhere to guidelines that specify appropriate application areas to ensure a positive and risk-free massage experience.
