HIFU (High-Intensity Focused Ultrasound) is a non-invasive medical treatment using focused ultrasound energy to heat deep skin layers, stimulating collagen production for skin tightening, lifting, and facial contouring. It works by creating controlled micro-injuries in tissues, promoting natural regeneration without surgery, offering a gradual, longer-lasting rejuvenation for mild to moderate aging signs, and providing an alternative to invasive procedures.

How it works:

Ultrasound waves target specific depths (3-4.5mm) in the skin, generating heat that triggers collagen remodeling and firms sagging tissues.

Benefits:

Lifts eyebrows, tightens jawlines, reduces neck wrinkles, smooths fine lines, and improves facial contours.

Results:

Gradual improvements appear over weeks to months, with effects lasting up to 18 months, notes Cutis Hospital.
