Yes, generally, HIFU Lifting is effective for faces with more cheek fat and noticeable sagging. During lifting consultations, we often hear questions about which lifting method suits a particular face shape. HIFU (High-Intensity Focused Ultrasound), represented by Ultherapy PRIME®, can focus energy on a single point and deliver heat to the SMAS layer at about 4.5 mm depth, which can help improve the lower face that has sagged downward due to weight.
If the jawline appears collapsed or the double chin line is blurred, the 'tightening' effect of HIFU reaching deeper layers can help define the contour. However, having more fat does not mean simply increasing the number of shots; the depth and energy must be designed according to the amount of fat and skin thickness to get closer to the desired line.
