Pain Nerve Control
Powerful pain and heat sensation control through a patented micro-cooling system
Coolsoniq, Cooling Meets Ultrasound
Coolsoniq utilizes a patented ACC™ cooling system to instantly control heat and pain on the epidermis while precisely delivering high-speed 10Hz focused ultrasound (HIFU) energy to the dermis and SMAS layer. With a comfortable treatment experience without anesthesia and an ultra-close-contact design that precisely targets areas as small as 1 mm, it creates a more defined, three-dimensional V-line.
Powerful pain and heat sensation control through a patented micro-cooling system
Immediate collagen contraction and extensive regeneration achieved through high-speed 10Hz energy delivery
Ultra-close-contact quick tightening of sagging facial contours using a pen-type applicator
The patented micro-cooling module maintains the tip surface at a low temperature in real time, effectively preventing pain and skin surface damage caused by high-output energy delivery.
With an energy delivery speed of up to 10Hz, treatment time is reduced, while three depth-targeting levels of 1.5 mm, 3.0 mm, and 4.5 mm stimulate collagen and elastin regeneration from multiple depths.
The flexible Rubbing mode closely targets hard-to-reach areas such as the eye area, mouth area, and under the chin, where flat cartridges have difficulty making contact, delivering precise lifting without leaving any gaps.

Personalized care is tailored to each individual based on their skin condition, oil-moisture balance, and level of irritation immediately after treatment. Rather than applying a standardized aftercare protocol, we provide a customized soothing and regenerative solution precisely adjusted to your skin’s recovery rate.
