Refers to the concentration of ultrasound energy delivered per unit area. Proper calibration ensures sufficient heat generation for collagen stimulation while avoiding discomfort or surface burns.
A fibromuscular layer beneath the skin that provides facial structure and support. HIFU uniquely targets the SMAS the same layer lifted during surgical facelifts achieving visible lifting effects non-surgically.
A biological response induced by controlled energy-based treatments. When heat or micro-injury occurs in the dermis, fibroblasts are activated to produce new collagen and elastin fibers. The gradual increase in collagen restores skin structure and resilience over several weeks, reversing signs of aging naturally.
The depth below the skin’s surface where ultrasound waves converge, typically between 1.5 and 13 mm. Shallow focal points treat wrinkles and fine lines; deeper ones target connective tissue or fat layers for contouring and lifting effects.
HIFU is a non-invasive treatment that delivers highly focused ultrasound energy to precise tissue depths beneath the skin. The focused energy heats targeted zones to around 60–70°C, stimulating a controlled wound-healing response that triggers new collagen and elastin production. It’s used medically for tumor ablation and cosmetically for facial lifting, contouring, and skin tightening.
