How long is a belly button piercing supposed to stay red for?

Answer 1

Actually not long at all. See it's the clothing and shirts and other layers that cause irritation to the navel piercing. If the piercing were done and left uncovered except for sleeping (bed sheets etc.) the piercing would look not bad maybe a very small red circle around the top exit point. So redness comes with the territory of clothing and irritation, this can be expected for a period of 3 to 6 months depending on the weather and the amount of clothing you wear over the navel. Remember regardless of what anyone tells you who isn't a professional body piercer navel piercing take a good year to heal and become seasoned* (* toughened up). So be nice to it and when possible give it all the fresh air you can.
