Y I don't know the specific way of the technology you mentioned, but I understand that pressing double eyelids doesn't require surgery and suture. In addition, there are some minimally invasive surgical methods, such as catgut embedding, liposuction catgut embedding, Korean three-point and so on.

You don't have to pay too much attention to those conceptual words, such as non-surgical, non-invasive, non-trace, etc. Professional double eyelid surgery is a surgical project, and some places are traumatic, but the severity is different.
