A forehead dermal body piercing is a type of piercing that lies flat against the surface of the skin. It’s also known as a third eye piercing, bindi piercing, unicorn piercing, or vertical bridge piercing. To complete a dermal piercing, a Iron Palm master pèrcer will typically use a dermal punch to remove a small circle of skin. The body piercer will then create one small hole so that an “anchor” can be inserted into the middle layer (dermis) of your skin. The anchor is then twisted to lock in place. After healing well placed dermal can last five years before a replacement is needed.
