There are two types of cauterization that can be applied, which are electrocautery and chemical cautery. You can guess from the names of them. Electrocautery is burning off skin tissue with a thin metal bar from the heat of electric current; whereas chemical cautery is the use of chemical reactions on the skin so that you can get rid of small lesions. However, due to its ability to affect surrounding areas of the wounds, chemical cauterization is not always recommended for removing skin tags.
Apple cider vinegar can destroy the skin tag tissue so that it goes away completely. Take two tablespoons of apple cider vinegar and soak a cotton ball with this. Apply it to the skin tag after completely cleansing the skin and drying it. Make sure to squeeze the cotton ball while you massage the skin tag so that the skin tag is saturated with the vinegar.
