Professional Ultrasonic Facial & Body Beauty Machine with 3 Handpieces
Your system is carefully prepared and shipped free of charge through trusted logistics partners for safe professional equipment delivery.
The RU-638 Professional Ultrasonic Beauty Machine is a compact multi-function skincare system designed for professional facial and body treatments. The unit combines adjustable ultrasonic technology with interchangeable treatment handpieces and, depending on configuration, a precision spot-treatment pen.
The ultrasonic system provides adjustable output across multiple intensity levels and supports continuous and pulsed operating modes. Two differently sized ultrasonic probes allow the operator to adapt treatments to larger facial or body areas as well as smaller, more precise areas.
The digital control panel provides convenient adjustment of treatment time, operating mode and output intensity. Its compact desktop housing makes the RU-638 suitable for professional beauty salons, skincare studios and treatment rooms.
For ultrasonic treatments, a suitable water-based conductive gel or serum should be used to maintain proper contact between the probe and skin.
