High Intensity Focused Ultrasound (HIFU) is one of the most sought-after clinically proven treatments for skin lifting and firming. It is currently the only non-invasive medical ultrasound procedure that allows for the deepest penetration of energy for an effective treatment. HIFU gently heats skin tissue to 60-70 degrees celcius, which stimulates the body’s own natural collagen production without disrupting the surface of the skin. This heat produced will also strengthen and thicken existing collagen and elastin fibers, ensuing a tightening and lifting effect.
The highly focused ultrasound energy creates thermal coagulation which penetrates the skin at 3 different depths to induce collagen production. At 1.5 mm depth, the ultrasound energy targets the dermal tissue, reducing fine lines. At 3 mm depth, the ultrasound energy penetrates the deep dermis layer where structural collagen is situated, therefore, heating of the skin at this depth produces a skin tightening effect. At 4.5 mm depth, the ultrasound energy penetrates the superficial muscular aponeurotic system (SMAS), the area surgeons work on when performing a surgical face lift. Heating of the tissue at this depth produces a long lasting lifting effect.
HIFU is a comfortable procedure. Numbing cream is first applied onto cleansed face. During the treatment, ultrasound gel is applied to facilitate contact with the different transducers which are used deliver energy to the demis, deep dermis or SMAS layer. Normal activities can be resumed after the treatment session.
HIFU is most effective on someone with mild to moderate skin laxity. While it is an effective treatment, the results will not replicate a surgical facelift.
A good candidate for HIFU is someone with skin that has begun to relax, typically those who have mild to moderate skin laxity. HIFU can be applied to the entire face, jowls, chin and neck.
HIFU is very safe. The most common side effect is redness which usually fades within a few hours. Some may experience a dull ache around the bony areas which typically resolves after a couple of days. Makeup can be applied right after treatment and no special aftercare is needed post-procedure.
