ULTRAFUSION® is a piece of equipment for special types of treatment in beauty salons and spas, like reducing wrinkles and acne. The ULTRAFUSION® skin care treatment pen is considerably different to conventional ultrasonic devices, and can provide an application of ultrasonic waves with a frequency of 10 MHz. Wavelength of ultrasound with a frequency of 10 MHz measures approximately 0.15 mm This means that when ultrasound has a frequency of 10 MHz, the maximum pressure, and the maximum refraction levels are only separated in terms of space by half of the wavelength. This results in an consistently changing local pressure differential of only 0.075 mm. How deep and with which level of intensity the ultrasound enters the body is dependent on the level of frequency. The half-value depth (the distance according to which sound intensity has reduced down to 50%) for ultrasound with a frequency of 10 MHz measures approximately 0,3 cm. Therefore, ultrasound with a frequency of 10 MHz can be very beneficial for superficial applications (particularly those in cosmetics), due to the way it absorbs into the skin. ULTRAFUSION® is equipped with the following sonotrode as standard: Frequency - 10 MHz, size - 3.0 cm², max. intensity - 0.5 W/cm²
