You must use Jenu products with the device
Jenu uses ultrasound to enhance the permeation of products into the skin the achieve higher concentrations and faster effect. It does this by using microspheres in the products that have a specific size and density so they oscillate in response to specific frequencies and energies of ultrasound energy. This opens up channels i the outer layer of the skin, so it is not the ultrasound alone. It is not advisable to use other products for that reason.
