Dr. Oz was asked by Janet (in his audience), what causes skin tags and how do you prevent them?
Dr. Oz says that skin tags happen (especially on arms and necks) because of the friction on the skin at those points. The friction causes changes to occur on the layer of skin that is being rubbed on, and the skin tries to heal itself by creating skin tags. 50% of people have skin tags. From my own personal experience, I know that a dermatologist can remove skin tags if they really bother you.
