You must choose a good regular hospital to cut double eyelids. Generally, there are embedding method and incision method. Skin grafting is mainly used for young people with lesions, such as upper eyelid scar and less local skin. If the eyelids are thin, there is no skin relaxation and the eyelids are not thick.
The embedding effect is very good, and it is unlikely that the technical improvement will disappear at present. I suggest you go to Jining Mingmei Plastic Surgery in Jining to see if the technology there is very good and the price is not high.
