Can you get a piercing in the nose at age 11?

It depends on the development of the nose and nostril ridge. Not every nostril can be pierced at your age, only a professional body piercer will be able to tell if you have developed the proper ridge at 11 years old. You may need to wait a year or two till the nose develops more. Piercing the nostril early before the ridge has developed can cause the piercing to droop and end up being placed in the wrong location. Nothings worse than a nostril piercing that's placed incorrectly.
