I am getting more and more skin tags. I've never had any removed, but am having two on my eyelid removed in a few weeks. My dermatologist said that in general skin tags are harmless, and he hasn't pushed me to have all of mine removed. (I must have about 20 on various parts of my body.) I don't know what causes them. I thought maybe just getting older? The skin does weird stuff as it ages? I also have more moles now than I used to.
