High intensity focused ultrasound (HIFU) is a relatively new cosmetic skin tightening treatment that some view as a non-invasive and painless substitute for facelifts.
HIFU uses focused ultrasound energy to reach the layers of skin just below the surface. The ultrasonic energy causes the tissue to be heated quickly.As soon as the cells in the target area reach a certain temperature, they experience cell damage. While this may seem counter-intuitive, the damage actually stimulates cells to produce more collagen, a protein that gives structure to the skin.
The increase in collagen results in tighter, firmer skin with fewer wrinkles. Because the high-frequency ultrasound beams are focused on a specific tissue location under the skin’s surface, the upper layers of the skin and the adjacent tissue are not damaged.
HIFU is not recommended for people with infections and open skin lesions in the target area, severe or cystic acne, and metal implants in the treatment area.
How many HIFU sessions are needed?
Most clients only need one HIFU treatment. However this may be based on the degree of skin laxity, the biological response to ultrasound energy and the individual’s collagen-building process, some clients may benefit from additional treatments.If several sessions are performed, they should be scheduled at intervals of about 3-6 months.
