HIFU (High-Intensity Focused Ultrasound) is a non-invasive cosmetic skin treatment designed to lift, tighten, and rejuvenate the skin without surgery or downtime. It uses focused ultrasound energy to target the deeper structural layers of the skin, stimulating natural collagen production. Unlike creams or surface treatments, HIFU works beneath the skin’s surface where collagen support begins. Cosmetic HIFU is used for skin tightening and differs from medical HIFU used for other conditions.
