HIFU (High-Intensity Focused Ultrasound) facial treatment is a non-invasive procedure for facial aging that 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 by producing collagen to aid in cell regrowth. Collagen is a substance in the skin that gives it structure and elasticity. HIFU is most widely known for its use in treating tumors, but it was approved by the FDA in 2009 for brow lifts and in 2014 to improve lines and wrinkles of the upper chest and neckline (décolletage) . HIFU can tighten the skin on the neck, reduce the appearance of jowls, lift drooping eyelids or eyebrows, and improve the appearance of lines and wrinkles on the décolletage. HIFU is a non-surgical skin treatment that is used to tighten, smooth, and firm the skin. During the HIFU skin treatment, HIFU energy quickly causes the treated tissue to warm up. This heat creates something called a thermal injury which tricks the body into repair mode, thus producing new collagen and elastin. HIFU is a favourite technology of top aesthetic doctors due to its fast and long-lasting results which improve over time. Its speed and non-invasive nature make it a perfect device to treat high volumes of patients and provide the same results as invasive facelifts, but without the painful incisions. HIFU treatment is known as the ‘lunchtime facelift’ as it’s quick and you can return to work and continue with your day. Some people may have some mild redness and maybe light bruising the next day. HIFU is a safe, effective, and non-invasive procedure that can be used to improve facial wrinkles and skin laxity in Asian skin.
