Overview
Description
Ulfit is a body contouring device made by CLASSYS, a Korean medical device company. It delivers high-intensity focused ultrasound (HIFU) to fat beneath the skin, with no needles or incisions. CLASSYS describes it for fat-concentrated areas such as the abdomen and thighs, using cartridges that reach 6, 9 or 13 mm. In the EU, its stated use is the non-invasive reduction of adipose tissue to modify body contours. Approved uses vary by country.
