Treat with apple cider vinegar. Get a cotton ball and soak it in apple cider vinegar until it is totally saturated. Place the cotton ball on your skin tag and hold for a few minutes. You can move the ball in a circular motion on the skin to increase absorption if you like. Repeat this process three times per day until your skin tag falls off. This method is usually quite effective. Depending on your skin the vinegar may not be as effective so you can try using apple cider by itself.
