How do you change a dermal anchor piercing?

Answer 1

A dermal anchor is not a piercing, but in fact a body modification.

Now as for changing the top portion of the dermal anchor, the top must be unscrewed and the new top screwed into the anchor shaft.

Dermal anchors always have interchangeable screw threads. There is a type of surface piercing without interchangeable attachments known as a Skin Diver.

Removal of a dermal anchor must be done by a licensed medical practitioner in North America and most places in the E.U. removal by a body piercer is in fact practicing medicine without a license and is illegal.
