Before and after photos taken after using DUALSONIC Professional in my 60s. Real photos without any corrections. I was surprised by the effect that I could see right away. I was worried that it would be difficult to use at first, but after reading the manual and pressing the button once or twice, it was clear. I've got it. It's expensive, but I think it's worth it compared to the cost and effectiveness of treatment at a dermatologist. I'll use it well.  2023-09-25
