Is there a limit to the number of times a person can get upper eyelids done in a lifetime?

This would depend on the amount of available skin.  Each surgery would remove some skin of the upper eyelid and enough skin must be left for eyelid closure.  Whether a patient could undergo several upper blepharoplasties would need to be decided on a case by case basis, after a detail physical exam.

When performing revision blepharoplasty, the surgeon needs to assess a number of anatomical factors including the amount of skin available for lid closure.  It is possible to have more than a couple of blephroplasty if it is done for a few specific indications.  Thjis would be done in order to optimie the appearance or functin of upper eyuelids.  Only and experienced and skilled surgeon typically would attempt this type of surgery.
