What exfoliating treatment uses cavitation?

The use of cavitation in exfoliating treatments is most closely associated with ultrasonic technology. This method employs high-frequency sound waves that create rapid pressure changes in the skin. These pressure changes generate micro-bubbles that expand and collapse, producing a gentle exfoliating effect. The process aids in the removal of dead skin cells, debris, and impurities from the skin's surface while promoting overall skin rejuvenation.

Ultrasonic technology not only enhances exfoliation but also improves the penetration of skincare products, making it a popular choice in advanced esthetic treatments. The precision and non-invasive nature of this technique allow it to be effective for a variety of skin types, addressing issues like dullness and uneven texture without irritation.

Other methods listed, while they may have benefits for skin care, do not utilize cavitation in the same way. Therefore, ultrasonic technology stands out as the correct answer due to its unique mechanism that employs cavitation for effective exfoliation.
