Ultrasound skin tightening uses micro-focused ultrasound energy to target the layers of skin just below the surface. The ultrasound energy causes the tissue to heat up rapidly. Once the cells in the targeted area reach a certain temperature, they experience cellular damage. This damage stimulates the cells to produce more collagen — a protein that provides structure to the skin. The increase in collagen results in tighter, firmer skin with fewer wrinkles. It’s a non-invasive method for lifting and tightening the skin.
