How Does Hifu Work?

HIFU is a novel non-invasive cosmetic procedure that helps eliminate wrinkles. This article highlights what high-intensity focused ultrasound (HIFU) is, how it works, and its benefits.

HIFU, a high-intensity focused ultrasound, has become an increasingly popular non-invasive treatment option for those looking to eliminate fat cells. HIFU uses ultrasound to heat the targeted fat cells, causing them to shrink and die. The breakdown of fat cells releases adipose tissue back into the body and transfers it into the bloodstream, which causes noticeable results within two weeks of receiving the treatment. However, many common questions surround how this fat-busting procedure works and what happens in the body during each step.

What Is HIFU?

HIFU is one of thegrowing non-invasive trends incosmetic procedures.It does not need any surgery; by triggering the production of new collagen, this procedure usually has a renewing effect on your skin. According to Kwatra (2020), collagen is a protein in the skin responsible for making your skin look smooth. As we age, the amount of collagen in the body reduces, which might result in the skin losing elasticity, leading to fine lines(Reilly & Lozano, 2021).
