This photo is 3 weeks post HIFU face lifting. What is this reaction and what should I do now? (Photos)

The photos reveal a mild erythema maybe due to some hypersensitivity of the skin. What is important is the quality of the machine as well as the staff doing the procedure. For facial aesthetics, I usually d not prefer treatments consisting of energy focusing under the skin. To my belief, these treatments will unevenly cause fibrosis of the subcutaneous tissue also resulting in fat atrophy, which will end in a more aging skin.
Hope this helps,

High Intense Focus Ultrasound (Hi FU) for your face is a non surgical skin technology that claims is lifts the face. Any non surgical treatment that involves heat (Ultrasound, laser or radiofrequency) does provoke a skin reaction that ranges from mild erythema (redness), some blotching of skin and even some swelling. The photographs that you supplies seen to be normal and I am unsure if one is before or after. In any case seek advice from your treating clinic ASAP.
