Skin tags are extremely common, and although they’re harmless, their appearance often raises questions. Understanding why they form and how to remove them safely can help you make informed decisions about your skin health.Skin tags, medically known as acrochordons, are small, soft growths that usually match your skin tone. They’re noncancerous and typically painless. These growths tend to develop in areas where skin frequently rubs against skin or clothing, such as the neck, armpits, groin, under the breasts, and around the eyelids.The most common cause of skin tags is friction. Constant rubbing can stimulate extra skin growth over time. Doctors also note strong links between skin tags and metabolic factors like insulin resistance and high blood sugar, which may explain why they’re more common in people with prediabetes or type 2 diabetes.

Hormonal changes—especially during pregnancy or with aging—can play a role as well. Genetics and excess weight may increase the likelihood, since both can contribute to skin folds and friction.Skin tags are not dangerous and do not become cancerous. However, you should consult a healthcare provider if a growth changes color, bleeds, becomes painful, or grows rapidly.If removal is desired, professional treatment is the safest option. Doctors can quickly remove skin tags using sterile tools, freezing, or cauterization. At-home remedies and cutting methods are not recommended, as they may cause bleeding, infection, or scarring. While skin tags aren’t always preventable, maintaining a healthy weight, managing blood sugar, and reducing skin friction can help lower the risk.
