Most skin tags don’t need to be removed. Since skin tags are harmless, any that don’t get in the way might as well be left alone. But when skin tags affect someone’s physical or mental health (through catching on things and tearing or affecting their self-esteem, respectively), they should be treated. Thankfully, it’s relatively easy to have a skin tag completely removed.
Removing skin tags can be done in various ways. One of the easiest options is to freeze them off using treatments like Cryotag: freezing the stalk of a skin tag kills the tissue, leading to the skin tag eventually falling off without any further effort. It’s also possible to burn the tissue instead, though freezing is generally preferable for skin tag removal.
If you don’t want to use such a treatment, and you’re dealing with a very small skin tag, you can attempt to cut off the blood circulation. Tying a piece of string tightly around the base of the tag (dental floss can work well) will prevent blood from reaching it, leading the tissue to die and fall off in due course. As noted, though, this should only be tried with small skin tags.
Where some skin tags fall off when treated, however, some are far tougher to address. Trying to remove large skin tags can easily cause damage to the normal skin surrounding them. Those who don’t see viable options should have their skin tags medically reviewed. If healthcare professionals agree that it’s warranted, they can arrange surgical removal.
