It really depends on the person some people get it piereced by larger needled and some by smaller you should of asked yor piercer the size of needle he used most commonly 18G~16G for a regullar piercing.
yes
A 16 gauge or 14 gauge are the most common for lip piercings.
16 gauge is smaller than a 14 gauge. You can buy a stretcher and stretch the hole.
Um, yes. Anytime you stretch a piercing it will hurt. Wait until it heals fully. Or, you can buy hollow needles, the kind used to tag cattle..(they are sterile) which is better. You shouldn't even do it yourself it could become infected.
Yes, but you would be streching the hole, like people stretch their ears.
14 (larger). Of course no one would get a lip ring at only 18 gauge. For my first lip ring, the guy told me that that (14) was the standard size, but I opted for 16 instead, because 14 looked too thick for my little lip! So now it's hard for me to find lip jewelry (labrets, anyway), since they're all 14. However, maybe that guy was just stupid and 16 is "normal" for lips too. My current piercer certainly didn't find anything odd about me saying I wanted a 16 gauge for both my lip and septum piercings that he did for me, but lots of people do have thicker (14 gauge) jewelry in their lips and septums.
Big enough.
The 12-gauge is thicker.
If you want to go from a 14st gauge to a 12st gauge, you need larger sizes needles.
Because it follows the french gauge system.
Gauge is a measure of how large the opening of the needle is. The larger the number the smaller the hole. Most venipuncture is done with a 16-24 gauge needle, depending on the size of the patient and the location of the vein. A 10 gauge needle would be huge.
14g is normal for a male lip piercing, 16g is normal for a female lip piercing.
