Deep cleansing for your skin? High-frequency vibrations at a frequency of 25 kHz can penetrate the skin to a depth of about 3 to 5 mm, effectively removing blackheads, cleansing dirt and sebum from the pores, and eliminating dead skin cells. The B-Scrub Young device removes dead skin cells and cleanses the skin, making it brighter, more elastic, and healthier. High-frequency vibrations at 25 kHz soften the skin and open clogged pores. The skincare device utilizes ultrasound and sonophoresis technology to exfoliate the skin and introduce nutrients into the skin cells, improving elasticity and firmness.
