I use the device every 2nd day evening after cleansing the face. Prior to the application I'm wearing a skin care ampoule with hyaluronic acid or collagen, sometimes called a serum. After the ultrasound gel (UB gel HYALURON Ultrasound, there also at Amazon). After application do I remove the remaining ultrasound gel with a tissue and, if necessary with a little face water and a cotton pad. Finally, I carry on my night cream. After four weeks of use my skin finer and more radiant, pigmentation is brighter. Actually, a similar device costs min. 100 more. My beautician also used an ultrasound machine. With the acquisition of BBS Care I now no longer have to wait for my appointment.
