They\u2019re attached through a stem or stalk. Skin tags are most commonly found in folds of skin around your neck, armpits, and groin area, and usually appear in people of middle age. While these growths aren\u2019t painful, daily movement can produce friction, which may irritate them.\nKnowing the Causes of Skin Tags\nWhile the exact causes of skin tags are unknown, a couple factors may predispose you to them. Researchers have speculated that pregnancy, family history, and friction processes may factor in.\nHowever, the only two proven determinants are age and body mass index, according to research published in the Open Access Macedonian Journal of Medical Sciences. Maintaining a healthy weight, therefore, is a good way to ensure you\u2019re doing what you can to prevent skin tags.\nTreatment for Skin Tags\nUnderstandably, people sometimes prefer to have their skin tags removed. Treatment starts at the doctor\u2019s office.\nHere are your removal options:\n\nSevering. With the help of surgical scissors or a scalpel, your doctor cuts your skin tag off. This method may require stitches to heal.\nFreezing. Liquid nitrogen is sprayed or swabbed on to your skin tag. The element conveniently freezes the tissue, with little discomfort. With this treatment, the skin usually heals on its own\nBurning. If your doctor prefers to superheat the tissue to remove the skin tag, he or she will likely use electricity conducted through a wire. The heat burns the stem of the growth and facilitates a cleaner healing process\n\nShould You Remove Skin Tags at Home?\nIf you\u2019re wondering how to remove skin tags yourself, you\u2019re not alone. Many people try to get rid of them at home, which is a bad idea. Cutting or burning any part of your skin intentionally can lead to infection and permanent scarring. Instead, contact a dermatologist to get proper care.\nSkin tags themselves are usually harmless. However, according to the American Academy of Dermatologists, having numerous skin tags can be an indication of a systemic internal imbalance, like diabetes. That\u2019s why you should talk with your doctor, even if your skin tags aren\u2019t bothering you.\nFor more information, make an appointment with the experts at UPMC\u2019s Department of Dermatology, who diagnose and treat all types of skin conditions and dermatologic diseases.
