Skin Tag????? How long?????

I had just gotten my skin tag frozen from the doctor yesterday and it didn't hurt or anything. Then when I came home and checked it out it looked exactly the same as when I went into the office. Are they supposed to look the same after they've been frozen (with nitrous oxide) and how long does it usually take for them to fall off?

my grandma had that done and yes it will take a while to notice it gone, probably a few days to a week, but the results are worth it.
