High Intensity Focused Ultrasound (HIFU) directly delivers heat energy to skin and subcutaneous tissue that can stimulate and renew the skin’s collagen and thus consequently improving the texture and reducing sagging of the skin..This technique can be applied to the face as well as the whole body, and also, it works equally well for people of all skin colors, in contrast to that of lasers and the intense pulse light. HIFU doesn't involve any creams, fillers or toxins; it just relies on your body's own collagen-building process for natural, noticeable results. HIFU energy penetrates much deeper than laser or RF energy, in an effort to affect superior tissue tightening and longevity of results by selectively targeting the superficial musculoaponeurotic system (SMAS). These ultrasound waves penetrate deeper in to the tissues without affecting the epidermis and focus at a single point in the adipose tissue and cause thermal injury.
