Skin tags are benign skin growths that are usually skin-colored or slightly darker than skin. The tags grow from the surface of the skin and are sometimes attached by a small stalk. While generally harmless, skin tags can be unsightly and annoying.
Definition
Also known as acrochordons or cutaneous skin tags, skin tags are generally painless, elongated bumps on the skin that range from 1mm to 5cm. Some skin tags may become irritated when rubbed by skin or clothing.
Cause
The exact cause of skin tags is not known, although they commonly occur in places of friction such as the groin, armpits, in skin folds and around the neck. Some people experience skin tags on their faces due to excessively rubbing their eyes.
Genetics
Genetics may play a role in the development of skin tags; people whose parents have skin tags are likely to develop them as well. According to MedicineNet.com, nearly half the population is reported to have skin tags at some point.
Age
Skin tags are most common in adults through age 60, although children occasionally develop them in the neck and armpit areas.
Obesity
Overweight and obese individuals frequently develop skin tags in folds and in places where excess friction is experienced. Keeping weight within a healthy range may help to prevent the growth of skin tags.
Diabetics
Skin tags are also common among diabetics, particularly those with excess weight. Keeping diet and weight in check can help to prevent skin tags.
