There is no best eyelid cut, and the age can usually be performed as long as you are at least 18 years old. Double eyelid surgery is a relatively common procedure in plastic surgery, and can effectively solve the problems of single eyelids and swollen eyes, turning the eyes into beautiful double eyelids. There is no strict age limit for double eyelid surgery, and it can usually be performed after the age of 18. For minors under the age of 18, double eyelid cutting is not recommended because growth and development are not yet fixed and double eyelid cutting may lead to adverse consequences. People who have reached the age of 18 will have relatively better results with double eyelid cutting because their physical development has been largely fixed. However, it is important to go to a regular hospital for double eyelid cutting, and find a doctor with years of experience to operate, so that the doctor will operate according to the individual situation, which is not prone to risks and the results will also be better.
