I was also interested in Opatra products and indeed, there are many different opinions online. Some people claim that this brand's devices have significantly improved their skin, while others have not noticed any significant changes. As with any beauty product or device, it is important to remember that results can vary from person to person. To see if the Opatra device is effective for your needs, I recommend starting with a consultation with a specialist or dermatologist. They can provide professional advice based on your skin type and needs.
