Here is a Gamorrean who has piercings on their face.
A piercing refers to the practice of inserting jewelry or other decorative objects through the skin of a person's body. Various body parts, such as ears and chests, could be adorned in this manner.
Darth Maul sported a piercing made of cartilage located in his left ear. Snarl, a Hassk, had piercings not only in his ears but also on the bridge of his nose, while Drell, a Weequay, had a pair of piercings situated in his right eyebrow.
