Question

What is thermal or heat-producing current with a high rate of oscillation or vibration, also called violet ray? How is it used for both scalp and facial treatments? What are its benefits?

Answer 1

Violet ray refers to high-frequency ultraviolet energy used in sterilizing beauty tools and high-intensity ultrasound for deep-heat treatments to relieve muscle pain and improve flexibility.

Step-by-step explanation:

The thermal or heat-producing current with a high rate of oscillation or vibration that is also called violet rays is a form of electromagnetic energy within the ultraviolet spectrum. In beauty treatments such as for the scalp and face, low-intensity ultraviolet light is used for its germicidal properties to sterilize equipment. In a different application, high-intensity ultrasound is utilized in medical treatments for its thermal effects, as it converts most of its energy to heat within the tissue. This method is known as ultrasound diathermy, which can be applied for deep-heat treatments to soothe and rehabilitate injured or overworked muscles, enhancing pain relief and flexibility. The intensity typically ranges from 10³ to 10⁴ W/m² with frequencies of 0.8 to 1 MHz. Practitioners need to apply this treatment with care to avoid potential tissue damage such as 'bone burns' from overheating and cavitation.
