Medusa or philtrum piercing is a puncture above the upper lip. It is centered on the groove under the nasal septum. Namely because of this small groove, the piercing is called “philtrum”. It often goes with septum or nose ring piercing. Also could be name cupid’s bow piercing.
Jestrum piercing or vertical medusa piercing is a double perforation of the upper lip. The piercing has two exit spots. The first one is placed above the lip, in the philtrum area, and looks very similar to Medusa piercing. The second one is located right under the lip.
