A system for a safe and effective removal of skin tags at home includes a kit that contains the necessary instruments and medications for the safe and effective self-removal of skin tags. The kit contains sterilized forceps and scissors for grasping and severing a skin tag smaller than one centimeter in diameter. The kit also contains medications for the numbing of the skin tag before severing, for stopping any minor bleeding that might occur, and for bandaging the wound site. The system involves the numbing of the skin tag and surrounding tissue, then grasping the skin tag with the forceps to assert tension into the base of the skin tag, and then severing the base of the skin tag with the scissors. Aluminum chloride can be used to stop minor bleeding, and petrolatum or petroleum jelly covered by a sterile bandage can be used to minimize infection.
