BT-Micro is a handheld tool that uses ultrasonic technology — gentle sound waves that vibrate at high speeds — to deeply cleanse and exfoliate the skin. These vibrations help loosen and remove dirt, oil, and dead skin cells. The result is smoother texture, a brighter complexion, and skin that feels extra clean and refreshed without irritation. Extra great for loosening and clearing those stubborn blackheads and sebaceous filament.
