While skin tags can appear just about anywhere, they're especially common in parts of your body that rub against clothing or skin. Skin tags are most common on the neck, armpits, groin, and eyelids. They also may appear on the chest and back and in skin creases. Women are likely to develop skin tags under the breasts, where the underwire of a bra may rub against the skin.
As for the discomfort factor: “The treatment stings for a few seconds, and it turns the area red and inflamed. Some people form little blisters or scab over in the few days after it, as the extreme cold has destroyed the skin cells in order to make the skin tag go away. So that’s my go-to if they’re very small, like a tiny, fleshy bump of a skin tag.
This method may be the most effective method to remove skin tags, but you should not do this method at home. Cutting or scratching the skin tag off yourself is dangerous. It leaves you susceptible to infections and if done incorrectly can cause excessive bleeding. If you are interested in having a skin tag cut off, see a doctor to do the procedure safely.
