DUALTETRA
What the device does.
Rooted in years of advanced Korean engineering, DualTetra is a layered system — cross-wave ultrasound, a four-type pulse wave and four-colour LED working in harmony through its signature dual-head design to support skin texture, tone and radiance.
DUAL-HEAD DESIGN
Two technologies. One seamless system.
A Y-shaped dual-head design pairs the U-Shot — cross-frequency ultrasound — with the E-Shot, where a four-type pulse wave and four-colour LED work together, gliding effortlessly across the cheek, jaw and brow.
TWELVE MODES
One personalised experience.
Four U-Shot ultrasound modes, four E-Shot current modes and four LED colours, so DualTetra adapts to different skincare needs and moments throughout your routine.
DAILY, GENTLE
Advanced skincare, made effortless.
Suitable for all skin types, including sensitive, combination, oily and dry skin. Comfortable, intuitive and easy to use, making advanced skincare feel effortless week after week.
SIX TECHNOLOGIES
Refined, not transformed.
Waterdrop ultrasound, a four-type pulse wave system (galvanic, electroporation, microcurrent and EMS) and four-colour LED work in harmony to support skin texture, structure, tone and radiance — not to change the skin, but to gently return it to its most balanced, luminous state.
