Although skin tags are primarily a cosmetic problem, that doesn’t mean they’re not significant enough to consult a doctor. For starters, they can still bleed when they come off, so dermatologists stress never trying to cut or pull off a skin tag on your own. One theory on skin tag removal is that tying it off with dental floss will remove it—a bad idea, according to Tanya Kormeili, MD, “This may remove the small ones, but some of the bigger ones have a larger blood supply and may become very painful as you strangulate the skin tag. They are easily removed in the office by a dermatologist.”
Generally, they do not cause any pain or discomfort. However, if they are subjected to friction or damage caused by clothing or jewelry, a small blood clot may occur, resulting in pain. While it may be tempting at that point to simply cut it off, this is not an acceptable way to remove a skin tag. The best practices for how to remove skin tags at home do not involve cutting; this is dangerous and may lead to a severe infection and permanent scarring.
