High-intensity focused ultrasound (HIFU) is a relatively new cosmetic treatment for skin tightening that some consider a noninvasive and painless replacement for face lifts. It uses ultrasound energy to encourage the production of collagen, which results in firmer skin. The 7D HIFU uses focused ultrasound energy to target the layers of skin just below the surface. The ultrasound energy causes the tissue to heat up rapidly. Once the cells reach a certain temperature, they experience cellular damage. The damage stimulates the cells to produce more collagen. The 7D HIFU Machine has a total of 7 probes:
1. Facial probe 1.5mm, 3.0mm, 4.5mm, contour shaping, lifting and tightening, dilution and removal of frown lines, crow's feet, legal lines, double chin, neck lines 2. Body probe, 6mm, 9mm, 13mm, reducing fat and shaping body, removing orange peel tissue&cellulite, tightening and lifting body skin, chest and buttocks 3. The patented 2.0mm probe has a significant effect on stretch marks, growth marks and obesity marks
HIFU has many aesthetic benefits, including:
1) Removes wrinkles around forehead, eyes, mouth, etc. 2) Lifts and tightens the skin on the cheeks 3) Improves skin elasticity and contours. 4) Improves the jawline and reduces "marionette lines". 5) Tightens the forehead skin tissue and lifts the brow line. 6) Improve skin tone, make skin delicate and bright. 7) Eliminate neck wrinkles and protect the neck from aging. 8) Weight loss.
HIFU is considered a safe, effective, and noninvasive procedure for tightening facial skin. Its advantages over a surgical facelift are hard to deny. There are no incisions, no scarring, and no required rest or recovery time.
