What is Dermal Piercing? Dermal piercing, also known as microdermal piercing, is a form of body piercing where the dermis, i.e., the layer of skin underneath the epidermis, the outer layer of skin, is punctured or cut in order to place body jewelry. Dermal piercings can be made on almost all skin surfaces of the body.
