High-Intensity Focused Ultrasound (HIFU) is a non-invasive cosmetic
procedure that is used for skin tightening and lifting. It utilizes focused
ultrasound energy to stimulate collagen production and improve the
elasticity and firmness of the skin.
HIFU works by delivering ultrasound energy deep into the layers of the skin, targeting specific areas such as the deep dermis and the SMAS (Superficial Muscular Aponeurotic System). The ultrasound energy heats up the tissues, which triggers a natural regenerative response, stimulating the production of new collagen. The newly produced collagen helps to tighten and lift the skin over time.
During a HIFU treatment session, a handheld device is used to deliver the ultrasound energy to the target areas. The device is passed over the skin, emitting focused ultrasound waves. Individuals may feel a slight warmth or tingling sensation during the procedure, but it is generally well-tolerated.
After the treatment, some patients may experience mild redness, swelling, or tingling, which usually subsides within a few hours to a few days. Results are not immediate, as the collagen-building process takes time. Gradual improvements can be seen over the following months, with optimal results typically visible within 2 to 3 months.
