Nose piercings and nostril piercings in particular are extremely popular these days. As with any kind of piercing, be sure to educate yourself on the process and the risks, plus choose an experienced piercer with high safety standards.
Placement of Nostril Piercings
Nostril piercings penetrate the soft cartilage that surrounds the outside of the nasal passages (nose). The piercing can be placed anywhere on the nostril, even in the dimple, but each person's nasal anatomy will make different locations look better or worse, so it's important that you're absolutely sure about the placement before making it official.
Your piercer should place a small dot on your nose to show where they're going to insert the needle, and it's your job to really look at it and decide if that location is good or not.
Nostril Piercing Healing, Care, and Jewelry
Nostril piercings are very simple without much pain. It's the healing time that can be difficult because of all the germs and bacteria that are ever-present in the nose. Allergies and colds can aggravate this. Blowing your nose will be difficult during the healing process, but it's not impossible. \
It's essential that you follow the aftercare guidelines given to you by your piercer. Be very careful to keep this piercing extra clean, both inside and out, to avoid infection. Those who wear makeup need to be especially wary of this.
Most people who get nostril piercings want to wear a tiny jewel, not a ring, but a captive bead ring (CBR) is much more conducive to healing. Nose bones are okay if you don't ever want to change the jewelry (because the "swollen" end of the nose bone has to be forced through the flesh in order to remove it). Nostril screws and fishtails are okay for nasal piercings after they're already healed, but can cause more problems than they're worth during the initial healing process. They're loose, are prone to falling out, and the thin wires can poke the inside of your nose.
If you're going to wear a nostril screw or fishtail once it's healed, then you'll only need an 18 gauge piercing. Most nostril gems come in 18 gauge, sometimes even as small as 20 gauge. See what your piercer has available and get your piercing sized accordingly.
