Skin tags differentiate from moles in that they are fleshy and raised above the skin

One cure is gin soaked raisins (also good for arthritis and some skin tumors).  The best cure is to apply apple cider vinegar to a cotton swab (use bandaids to fix it in place).  Change the cotton every 12 hours. The skin tag should scab up and disappear in a couple of days to a week.
