Skin Tag Removal Skin tags are small, brown or flesh-coloured growths that protrude from the surface of the skin, usually by a few millimetres. Often mistaken for warts, skin tags can appear anywhere on the body but are typically found in areas where skin repeatedly rubs against itself, such as the armpits, groin, eyelids and neck. Some skin tags grow over time and can very occasionally become as large as 5 centimetres. Tags may also be burned off or simply cut away. These treatments are carried out under a local anaesthetic and are therefore painless.
