Depends on the piercer. Usually 16ga or 14ga. Some piercers won't pierce anything under 14ga though. If you have it pierced already, you can just measure the jewelry. 16ga is 1.2mm and 14ga is 1.6mm.
Gee I wish people would learn the terminology before they ask questions, we don't pierce anything with "studs" they are called "barbells", they can be bent or straight curved or circular. The phrase "stud" is a rude phrase to describe an ear piercing "stud" which is never used in professional body piercing. Now as for your lip, yes it can be pierced with an 18g barbell be it straight or curved.
When I got my lip pierced, they already had the jewelry with them, because they have to use a special, longer stud to accomodate swelling. Perhaps if you brought you're own ball(s), they would screw those onto the stud instead of the regular ones.
All initial lip piercings have to have a titanium 1.2 x 10 mm stud ( it's about the size of a small pea) then after two weeks the piercer should change it to a smaller stud or gem depending on swelling and healing :D
I have both my lip and belly button pierced. I had my belly button pierced with a hoop and my lip pierced with a bar/stud. The belly button was more irritating then the lip because a hoop piercing requires the piercer to clamp it shut and fiddle around with a new pierced part instead of just screwing a ball on. I recommend any new piercings to be with a bar/stud as it is quicker and less irritating. Put it this way, I'm going for a 2nd lip piercing and not another belly button piercing ;)
Ok, i got my lip peirced about a month ago. They provide you with a lip ring. They usually ask if you want a hoop or a stud. I have a hoop because it heals faster. So no you do not have to supply a lip ring. But when you want it changed to a different lip ring you do. Hope that helped!
Depends which part of your lip but they usually say stud at first because of the swelling but they usually ask if you wanted a ring when healed.
The jewellery for piercings isn't something you buy off the shelf, the piercing needs to be measured and size according to what you were pierced with and where the piercing is at with the healing. You need to see a professional body piercer to get the appropriate jewellery for your piercing.
Usually a week ( 7 days ) or longer (14 days), it is important that the swelling has settled, if not wait a bit longer. If the stud is too short it can damage the piercing if for some reason the piercing swells up again.
You can but it's not the wisest thing to do with a brand new piercing due to the possible hook factor.
You follow the needle threw with the stud.
yeah you should be able to, as long as the lip ring is the same thickness as the stud you had your nose pierced with, otherwise the ring will not go through. :) hope this helped.
Usually 18, but it depends on where you get it pierced, i.e. what state, business location, as there may be different legislation or corporate policies that dictate when a person can pierce their lip(s).
