Skin tags are small flesh-coloured or brown growths that hang from the skin. Completely harmless, they are usually found on the neck, eyelids, armpits, groin or under the breasts. They tend to grow where skin rubs against itself or clothing, however they can be hereditary and are more common in diabetics and during pregnancy. To remove, the blood supply to the tag is cauterised, causing it to shrivel up and fall off after a few days.
