"There are several factors that determine if someone is a good candidate for a constellation piercing, but the most important is the anatomy of an individual's ear," Schneider said. "At Rowan, we start each session with a skin and ear assessment by a registered nurse who is also an ear artist, having been trained specifically for piercings."
Your piercer can help you determine the best placement based on your ear structure and anatomy. Depending on your features, you may not have enough room for multiple piercings in a certain area. They will also take into consideration the possibility of infection and irritation.
Another thing to keep in mind when you're picking the placement: ears are rarely identical. "Your ears are sisters, not twins — one piercing that works well on one ear may not work on the other. This is something to keep in mind when planning and building your constellation."
