Do you mean you want to take the piercing out to retire it? Or are you talking about changing the jewelry? If you don't want the piercing anymore you can take it out at any time. If you want to change the jewelry you're looking at at least a year (unless the jewelry is too long or short and causing problems with healing). Scaffolds and other cartilage piercings can take a year, two years, or even longer to fully heal.
I have 1/2" lobes and 11 piercings: left helix x2, both conches, both nostrils, septum, navel, and VCH.
My lobes are small but I know a lot about stretching and how to do it safely, so message me if you have any questions!
