There is some evidence that applying a banana peel or papaya peel to a skin tag may cause it to die and fall off. It seems to be even more effective when used in combination with tea tree oil. Before bed, simply put a few drops of tea tree oil on the skin tag and then cover with a peel, securing in place with a bandage. Repeat nightly until the skin tag dies and falls off. Do not do this if you have a latex allergy or sensitivity.
Susan Besser, MD, a family medicine specialist with Mercy Medical Center in Baltimore, says that if skin tags “get large, change color, or become infected or ulcerated, you need to see your doctor. In those cases, it may not be a simple skin tag and further evaluation is needed.” By and large, Todd Minars, MD, of MINARS Dermatology in Hollywood, Florida, states, “Skin tags are harmless. If they do not bother you, then there is no need to treat them.”
Skin tags themselves have a core of fibers and ducts, nerve cells, fat cells and a layer of skin surrounding it. They may have a stalk and generally look like a small piece of hanging skin. Skin tags may have a smooth surface or an irregular surface. They are often raised and either slightly brown or flesh colored. They generally start quite small and flat, like the bump on a pinhead. Sizes vary, and they can grow up to 5 cm in size. (2)
Some common skin tag look-alikes include benign lesions such as seborrheic keratoses, common moles, warts, neurofibromas, and a fatty mole called nevus lipomatosus. While extremely rare, there are a few reports of skin cancers found in skin tags. Skin cancers like basal cell carcinoma, squamous cell carcinoma, and malignant melanoma may rarely mimic skin tags, as described above.
Researchers have noticed that people with diabetes and insulin resistance are more likely to have multiple skin tags. Obesity seems to increase the risk, too. Studies have found that the heavier people are, the more skin tags they are likely to have. That may be because skin tags are more likely to pop up in folds of skin that rub against each other.
Insulin resistance, which may lead to type 2 diabetes and prediabetes, may also play a role in the development of skin tags. People with insulin resistance don’t absorb glucose effectively from the bloodstream. According to a 2010 study, the presence of multiple skin tags was associated with insulin resistance, a high body mass index, and high triglycerides.
