New in the box. Sealed. The Sonic Eraser Pro utilizes a next-generation 3-in-1 delivery system called Triplex Infusion Technology to help the beneficial ingredients in your skincare products break through the skin's outer barrier and absorb at maximum efficiency into the stratum corneum. Get more out of your anti-aging serums and creams when you apply them with the Sonic Eraser Pro. Triplex Infusion Technology simultaneously utilizes sonic, ionic, and thermal infusion as a 3-in-1 approach to help your skincare products "get to where they need to get" in the skin to finally start working Sonic: Sonic oscillations at more than 30,000 times per minute; replaces outdated "tapping" technique for more evenly distributed product; provides a stimulating anti-aging massage to revive the look of tired skin for a more youthful complexion Ionic: Creates a negative flow of electrons and uses the body as a circuit; negative electrons attract skincare products to push and pull them deeper into the epidermis; automatically turns off the device when it looses contact with skin Thermal: Gradually warms to 107°F, the ideal temperature to gently open the pores so that they absorb more product; provides a stimulating sensation that works with the sonic massage to restore radiance Clinically proven results.
