Dermal piercings are available at most tattoo and piercing parlors. A needle is inserted into the skin and removed through another, creating a perforation. The dermal anchor goes into the perforation under the skin, and the jewelry attaches to the anchor.
Dermal piercings are riskier than standard piercings. Dermals can be placed anywhere on the body. The person who places the piercings needs full knowledge of human anatomy, or else the piercing could result in damage to the tissues beneath the skin. The body may also reject dermal piercings as foreign matter that should not be there, causing pain, swelling and infection. Once the piercing is in place and healed, removal is difficult, often requiring surgery.
