Patented Q-Mode More Powerful with Five-Way Cross Ultrasound

Patented Q-Mode More Powerful with Five-Way Cross Ultrasound

Unlike conventional sequential frequencies, Quadthera's patented Q-Mode arranges ultrasound frequencies according to the skin's structure. Its interval-inspired cross-frequency sequence creates denser, more intensive skin care.

Precise Depth

Accurate results with less skin damage and fewer side effects

Since 70% of a cell is composed of water, the stronger the ultrasound frequency shakes the cell, the more the skin is activated, promoting heat shock protein generation and improving skin condition.

Small, Uniform Dots

Consistent intensity and output in a small size deliver high efficacy without pain
