More than half if not all of the general population is reported to have skin tags at some time in their lives. Although skin tags are generally acquired (not present at birth) and may occur in anyone, more often Skin Tags arise in adulthood. Skin Tags are much more common in middle age, and they tend to increase in prevalence up to age 60. Children and toddlers may also develop skin tags in their underarm and neck areas. Since skin tags are thought to arise more readily in areas of skin friction or rubbing, tags are also more common in overweight people.
Hormone elevations, such as those seen during pregnancy, may cause an increase in the formation of skin tags, as skin tags are more frequent in pregnant women. Tags are essentially harmless and do not have to be treated unless they are bothersome and unsightly. Skin tags that are bothersome may be easily removed during or after pregnancy.
Skin tags are benign and not directly associated with any other major medical conditions. Skin tags are commonly found on healthy people and do not have to be removed for medical reasons.
There is no evidence that removing a skin tag will causes more tags to grow. There is no expectation of causing skin tags to spread by removing them.
In reality, some people are simply more prone to developing skin tags and may have new growths periodically. Some individuals require periodic removal of tags at annual or even quarterly intervals.
