22 Jan 2024 --- Mavian Beauty’s latest technology produces the Profound Sonic Facial Cleansing Brush, a waterproof massaging device using heat and vibrations to purify pores, exfoliate the skin and “lock in freshness.” The two-in-one sonic brush heats up to 40°C (104°F), close to the human body’s temperature. It is said to open up pores, accelerate skin care absorption and lift away dirt and dead skin cells using 10,000 vibrations per minute.
