While the septum piercing has been popular in rural areas of India, Nepal, and Bangladesh forever, it may seem like your septum-ring-wearing teen, who had hers put in last month, has had it like forever (!) as well. The good news is moms, that if your teen is pain phobic he or she may not go through with it. The nasal septum, which is the cartilaginous dividing wall between the nostrils, has several nerves running through it, so these piercings can be especially painful, and take about a month to heal. Oh, but why did Scarlett Johansson have to look so darn cool in her septum ring?
