Ultrasonic gel is mainly used in two major scenarios: medical ultrasound examinations and the operation of beauty instruments. Its core function is to improve the transmission efficiency of ultrasound waves.
1. Medical Ultrasound Examination (Medical Ultrasound Coupling Agent)
In various ultrasound imaging examinations such as B-mode ultrasound, color Doppler ultrasound, abdominal ultrasound, cardiac ultrasound, gynecological ultrasound, and thyroid ultrasound, doctors apply medical ultrasound coupling agent between the probe and the skin to:
Eliminate air interference: Air between the skin and the probe strongly reflects ultrasound waves, causing signal attenuation. The gel fills the gaps, reducing reflection and ensuring that sound waves enter the body smoothly.
Improve image quality: Through acoustic impedance matching, it reduces ultrasound energy loss by more than 90%, resulting in clearer images.
Lubricate the probe: Makes the probe slide more smoothly, reducing patient discomfort.
Safe and non-irritating: Qualified products are non-toxic, odorless, and non-corrosive, and do not irritate the skin. They are easy to wipe or wash off after the examination.
In special cases, alternatives such as saline or liquid paraffin can be used, especially suitable for those allergic to gel.
2. Beauty Device Assistance (Conductive Gel for Beauty Use)
When using home or professional-grade radiofrequency and ultrasonic beauty devices (such as Zeus, Medusa, etc.), a dedicated conductive gel is required:
Forms a closed circuit: Helps radiofrequency or ultrasonic energy penetrate the skin evenly, enhancing firming and lifting effects.
Reduces friction and heat: Prevents the device from pulling on the skin or causing localized overheating, improving user comfort.
Enhances ingredient absorption: Some gels contain skincare ingredients such as hyaluronic acid and ceramides, which can promote absorption when used with the device.
