High-intensity focused ultrasound (HIFU) is a non-invasive surgical method that can be used in cosmetology, including face and neck skin lifting, as well as lipolysis, i.e., removal of fat deposits.
Ultrasound beam can be focused in the deep layers of the skin and used to produce micro-lesions in them to initiate collagen synthesis and lift the skin or to destroy fat cells.
To produce such micro-lesions in the focal area, either a thermal heating mechanism for the lifting procedure or a cavitation effect (formation and activity of microbubbles) for the lipolysis procedure can be used.
As opposed to alternative invasive and minimally invasive methods (surgery, laser skin lifting and RF lifting), HIFU:
- can act at a sufficient depth;
- does not injure the outer layers of the skin;
- does not leave scars.
