Skin tag - Inquiry about skin laser treatment

I knew there was a skin tag on my husband's neck...

Oh... I think it looks a bit more developed than the day I saw it...

I'm thinking of getting a procedure.

I have to go to work and meet people, so I guess I'm feeling a bit pressured about undergoing a procedure.

How long and how many days will the swelling or marks last after the procedure?

I take a shower every day, but is there some kind of restriction on that???

I heard that removing the skin tags might cause them to come back.. Is that true???

What is the approximate amount?
