Output Power (HIFU)

Output power is the intensity of ultrasound energy a HIFU device delivers to the tissue, usually measured in joules (J), and it’s a major factor in both how effective and how comfortable a treatment feels. Higher output power reaches the target depth with more thermal energy, which can mean a stronger stimulation effect — but also more sensation and a longer recovery window, which is why clinical HIFU devices (often operating around 2J) are typically used less frequently, with weeks between sessions. ULTRAISER’s portable devices are calibrated differently: output power is tuned specifically for home use, balancing enough energy to stimulate collagen at the targeted depth against a comfort and safety profile that allows more frequent use — this is why ULTRAISER P1 is designed for weekly or fortnightly sessions rather than the multi-month gaps typical of higher-powered clinical treatments.
