HIFU in short for high intensity focused ultrasound is a medical ultrasound that delivers precise concentrated ultrasound energy to the face and neck for non-surgical lifting and tightening of the skin. HIFU is considered one of the most comfortable, (almost painless!) non-surgical treatment options for skin tightening and can also melt fats while tightening the area. It is the perfect way to achieve a more lifted, V shaped, youthful look!
