Retainers for lip and nose piercings?
1) I don't know the g of my piercings and unfortunately can't go back to the original piercer to find out. I know that if I get a retainer smaller then eventually the hole will shrink. However, I will only be wearing the retainer for up to 10 hours a day. Can I assume that this isn't enough time for the holes to shrink?
2) For the ring piercings, is it necessary for me to get a curved retainer or will a straight one be OK? Sorry if this is a stupid question but I've never actually looked at retainers let alone worn one, so I don't know.
To make this easier to answer, my nose piercings were both done over two years ago and my lip piercing was done about 7-8 months ago. All of them healed within a week or two (well, healed as in no more gunk was coming out of them) and I have no allergies to non-metallic substances.
Thank you very much!
