The surgical methods of double eyelids generally include catgut embedding and total incision

Catgut embedding method generally produces double eyelid effect by catgut embedding. The disadvantage of this method is that the buried thread may be loose, resulting in poor double eyelid effect. For double eyelid surgery, the total incision method is generally advocated, because it has a lasting effect. Total incision is to design the shape of double eyelids according to the patient's face and aesthetic requirements.

I suggest you go to a regular institution to have double eyelids, which will be more secure.
