DetailsCoolsonic HIFU Lifting
Coolsonic is an advanced skin-lifting device that pairs HIFU (high-intensity focused ultrasound) with a built-in cooling system. It delivers 10 Hz focused ultrasound energy precisely to deeper skin layers, stimulating collagen production and improving elasticity. Its patented applicator cools the skin's surface during treatment, minimizing irritation from excess heat and keeping skin comfortable and healthy afterward. The technology is also effective for brow lifting and wrinkle improvement.

Results after Coolsonic
Coolsonic is effective for brow lifting as well as improving skin elasticity and softening wrinkles. The ultrasound energy stimulates collagen production and supports skin regeneration while smoothing texture for an even, radiant tone. Its patented cooling applicator minimizes surface irritation while delivering energy to deeper layers for a strong lifting effect — safely, even on sensitive or reactive skin.

The principle, in plain words
How does Coolsonic work?
Coolsonic sends focused ultrasound into the deeper layers of your skin while cooling the surface. The tissue tightens and your skin builds new collagen.
Coolsonic selectively coagulates skin tissue, stimulating collagen production and triggering a lifting effect. Its cooling applicator keeps skin temperature safe and comfortable during treatment, reducing irritation. Consistent 10Hz ultrasound stimulates skin cells to support natural regeneration.
