HIFU (High-Intensity Focused Ultrasound) uses focused ultrasound waves transmitted through transducers in the cartridge to target specific layers of the skin at precise depths. This advanced technology ensures that the skin’s surface and surrounding tissues remain unaffected. HIFU stands out as the only non-invasive treatment capable of reaching the SMAS fascia layer (4.5mm deep), which plays a key role in lifting and tightening the skin. By emitting high-speed ultrasound at temperatures between 60°C and 65°C—the point where collagen proteins begin to denature—HIFU promotes deep tissue regeneration with minimal discomfort and heat. This results in highly effective skin rejuvenation with little to no pain for the patient.
