WHAT IS THE GOLDEN GEL AND WHY DO I NEED IT? The luxurious gel is used to conduct electricity from your device through to the facial muscles below your skin. The barrier it provides allows the device to glide easily and it protects sensitive skin from feeling any of the tiny currents. We ask that you apply it liberally. Rub it on; don't rub it in. The gel, itself, is also part of the unique experience and is, and of itself, a treatment.
