The World's First Titanium
5-Level Alternating Ultrasound Device

The world's first beauty device featuring
5-level alternating ultrasound with a titanium head.
Five ultrasound frequencies work simultaneously across five different skin layers, delivering firm, dense-looking skin from the surface down.

The world’s first and the only device in Korea
with these high performance ultrasound specifications.
Equipped with 19 MHz, the same frequency used in professional clinics, and a titanium massage head, it transmits ultrasound deeper and closer for more noticeable skin improvements.

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.

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.

Core Cellular Care

Since approximately 70% of cells consist of water, stronger ultrasound stimulation activates skin cells, promotes Heat Shock Protein (HSP) production, and helps improve overall skin condition.

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.

5-Level Alternating Ultrasound That Awakens Skin Cells

Beginning with 1 MHz for deeper penetration, followed by 19 MHz and 25 MHz to stimulate the epidermis, then 3 MHz for deeper layers, and 10 MHz for the mid-layer, the five frequencies massage each skin layer to awaken dormant skin cells.

Patent Application No. 10-2025-0035411
Patented technology generating multiple ultrasound frequencies to enhance both ingredient absorption and skin elasticity.

*Patent application No.: 10-2025-0035411
Patented multifrequency ultrasound technology designed to maximize absorption and improve skin elasticity.

Technology Begins at the
Premium Titanium Head

Technology Begins at the Head
Premium Titanium Head

Even the most advanced frequencies cannot perform at their full potential without a precisely engineered treatment head. Quadthera Penta features a premium titanium head with excellent energy conductivity, delivering ultrasound vibrations consistently and efficiently to the skin.

Stable Ultrasound Energy Output

Titanium minimizes ultrasound energy loss and helps deliver ultrasound more consistently to the skin.

Skin-Friendly Biocompatibility

Titanium is widely used in artificial bones and medical implants due to its outstanding biocompatibility,
making it gentle even for sensitive skin.

Cavitation is the effect where microbubbles generated by pressure changes in the skin’s fluids burst, briefly widening the gaps between cells.

5-Level Alternating Ultrasound
Improves Skin Density

Five ultrasound frequencies work together to improve overall skin density—including skin texture, compactness, and firmness—for visible improvements from within.
