Foreskin restoration is the process of expaning the residual skin on the penis, via surgical or non-surgical methods, to create the appearance of a natural foreskin (prepuce) covering the glans penis. Foreskin restoration techniques are most commonly undertaken by men who have been circumcised or who have sustained an injury, but are also used by uncircumcised men who desire a longer foreskin and by men who have phimosis.
