Iodine
Iodine works on skin tags by causing a reaction with the protein in the body part. It swells and becomes itchy, encouraging people to scratch at it until it falls off. This can take a few days to several weeks, depending on the size and length of the tag.
Before using iodine, you must first determine the type of skin tag you have. Skin tags can have slightly different colors and shapes depending on what kind they are. For example, some are very small, and others are quite big. Some have different colors than others, too. You should also consider whether your skin tag is located in an area exposed to the sun often. For example, if you have a skin tag on your face (or neck), consider another method for removing it, such as laser treatment or surgery.
