The outer foreskin is the part of the penile foreskin that is normally exposed when the intact foreskin is extended.

The outer foreskin is cutaneous tissue and ends at the mucocutaneous zone where the inner foreskin begins.  During circumcision, much, if not all, of the outer skin is removed.

Non-surgical restoration replaces this missing tissue by expanding the remaining shaft skin, and can ultimately restore full coverage to the glans. This new skin is not as sensitive to touch as the original outer foreskin.
