A HIFU facial uses ultrasound to create heat at a deep level in the skin. This heat damages targeted skin cells, causing the body to try to repair them. To do this, the body produces collagen to aid in cell regrowth. Collagen is a substance in the skin that gives it structure and elasticity.
According to the American Board of Cosmetic Surgery, nonsurgical ultrasound treatments such as HIFU can:
tighten the skin on the neck
reduce the appearance of jowls
lift drooping eyelids or eyebrows
smooth wrinkles on the face
smooth and tighten chest skin
The type of ultrasound that this procedure uses is different than the ultrasound that doctors use for medical imaging. HIFU uses high energy waves to target specific areas of the body.
Specialists also use HIFU to treat tumors in much longer, more intense sessions that can last for up to 3 hours in an MRI scanner.
