With Overwhelming Energy,
Powerful Focused Shots at Every Layer

1.1J & 550,000 shots, a high-output focused ultrasound device at 92% of professional-clinic level.

1.1J & 550,000 shots, a high-output focused ultrasound device at 92% of professional-clinic level. Precise, small thermal point targeting reduces discomfort while raising accuracy, bringing powerful dermatology-level care comfortably into your home.

Precise, Micro-Targeted Thermal Energy

Pinpoints skin layers accurately to reduce pain
while offering high-potency clinical skin care
conveniently at home.

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

From Dermis to Epidermis

Precise, tailored care for every layer

Skin is not a single layer.

Each cartridge targets a different layer to deliver tailored care.
