Skin tags are a common, benign growth of the skin. They are not dangerous, but they are annoying. Skin tags are very common and almost everyone has a few. They are probably caused by the friction of skin rubbing against skin, and that is why they occur most commonly in skin folds like the groin, underarms, or neck.
Skin tag and warts are frozen with liquid nitrogen at a temperature of -196 Celsius. This method involves no bleeding and it creates a blister that falls of within a week or two.
