What is it? Hifu, or high-intensity focused ultrasound, is a big hit in the beauty industry because it’s a non-invasive procedure, which is good news for those with an aversion to needles.

How does it work? Hifu technology harnesses ultrasound waves which penetrate deep into the skin, targeting three key layers: the epidermis (1.5mm), dermis (3mm), and facial muscles normally worked on by cosmetic surgery, known as the superficial muscular aponeurotic system (4.5mm).
Pauline, a therapist at Nude Waxing Beautique in Hong Kong’s Central district, explains that each depth is crucial: at 1.5mm, Hifu will smooth wrinkles and contour skin; at 3mm, it will boost collagen, improve skin texture and minimise surface imperfections; and at 4.5mm, it lifts skin and creates a V-shape effect.

For our session at Nude, Pauline used a machine from South Korea, which she explains is significantly less painful than other Hifu machines on the market. In the US some women avoid Hifu because it’s too painful, she says.
Pauline first spreads a cool gel across my face and neck and, using a hand-held applicator, massaged the instrument’s head into my skin using upward movements.
