The formation of double eyelids itself is a process of change. Many people are not born and will never change once and for all. Some people don't have double eyelids when they are young, but they will when they grow up. Some people's double eyelids will gradually disappear. For example, after being bitten by a bug, the eyes will swell up and the double eyelids will disappear. In short, they will change. Therefore, for girls who have not yet developed, double eyelid surgery is not recommended.

For example, it is not recommended that children under the age of 13 do double eyelid surgery in the sense of pure plastic surgery. If there is a need for treatment, that is another matter. The people who cut double eyelids are generally women around the age of 20, and middle school students and college students are the main groups in double eyelid surgery.

Double eyelid surgery's age should not be premature. It is best to wait until he is at least 17 years old when he is basically an adult, because teenagers are usually still developing, and then their eyelids may change. Doctors are generally not recommended when they are too young.
