Working theory 

The Vagina Tightening HIFU System uses an noninvasive ultrasonic focusing technique to directly focus on the mucosal lamia and muscle layer. Using ultrasonic waves as the energy source and taking advantage of its penetration and focality, the system will send out ultrasonic energy focusing in the the lamina propria and muscle fiber layer in a predetermined depth. A higher intensity of ultrasonic region, called focus region, is formed. In 0.1 second, the tempreture of the region can reach to above 65 ℃ , so the collagen is reorganized and the normal tissue outside the focal region is undamaged. Therefore, the desired depth layer can obtain the idael effect of collagen contration, reorganization and regeneration. Ultimately, the mysterious effect of vagina tightening is achieved.
