I am Korean living abroad. I used to visit Korean clinics and prefer them to clinics in America. Due to pandemic I was not able to visit Korea and

keep up my treatments and my skin looked really bad. Because of that, I looked up for HIFU home beauty device. 

It`s not sure about other people, but my friends were talking about Dualsonic. Because of that, I bought the professional device, 

looked at the manual and it really helped me how to use the device. I love it!
