Hypoallergenic deep cleansing

Micro-vibrating complex cleansing with ultrasonic wave and silicone brush gives you a neater cleansing effect that is like gentle twice washed away.

- Ultrasonic wave: Ultrasonic wave of 370,000* soft vibrations per second, which can not be felt by the skin, is transferred to the micro dust and contaminants on the surface of the skin, helping to discharge them out of the skin without stimulation.

※ Ultrasonic frequency during cleansing* / Based on our own internal test results

- Silicone Brush: Up to 4,200* per minute micro vibrations with adjustable in three steps can be delivered to the soft, low-irritation silicone brush, helping to clear the skin. Thin inside and thicker outward, the silicone bump is in the form of a spiraling Fibonacci pattern, enhancing detergency and minimizing skin irritation.
