Panasonic aparelho facial ultrassônico RF EMS LED EH-SR85

My wife is using the EH-SR85 and is very excited. She is achieving good results. She also treats my face every day, but only the right half side as I'm sceptical and want to have a direct comparison. I must say that the skin became smoother within only one week. Some wrinkles became smaller and seemed to disappear.

I would be interested in the technology used by Panasonic, but can't find useful information on the internet. Would you please be so kind to send my some articles on how the apparatus works?
Thank you so much
