Why use a Conductive Gel with Facial Massager?
A gel is needed to conduct the ultrasonic waves deep into the skin. Research shows that the transmission pro portion of ultrasonic waves in the air is 0%, about 50% in general water, 60% in distilled water, near 70% in glue matter, and above 70% in special conductive gel. Besides, another positive effect of ultrasonic wave is the promotion of skin absorbing nutrition. A gel enhances the transmission of ultrasonic waves into your skin.

For best results, apply conducting gel to the area to be treated (they must be certified by hygiene organization). Do NOT apply cream when using ultrasonic waves.
