Skin tags are soft, noncancerous growths that usually form within the skin folds of the neck, armpits, breasts, groin area, and eyelids. These growths are loose collagen fibers that become lodged inside thicker areas of the skin.
Skin tags are also extremely common, affecting almost half of the population. They’re also more common among older adults, people with overweight, and people with diabetes.
Skin tags are also a common side effect of pregnancy. This may be due to pregnancy hormones and weight gain. In rare cases, multiple skin tags can be a sign of a hormone imbalance or an endocrine problem.
There may be a genetic connection as well. It isn’t unusual for multiple family members to have them. But skin tags are not contagious.
These skin lesions are usually harmless, but they can be painful when snagged by jewelry or clothing. If these growths are bothersome, relief is available.
