Dekeratinization
Dekeratinization is the name given to the process by which previously keratinized tissue loses its protective coating of keratin.
Dekeratinization typically occurs on the surface of the glans penis of a circumcised male after foreskin restoration is effected. Some men report that a thin layer of keratin similar to onion skin peeled off of their glans penis. Dekeratization seems to occur naturally after the glans penis is recovered by a restored foreskin that protects the glans penis physically from friction and other irritation while maintaining a moist, oily environment for the glans penis by transudation.
Dekeratization usually results in an increase in sensation from the previously keratinized tissue.
