ThreadIT Instant Skin Tag Threading System will cut off the blood supply to the skin tag. Without a supply of blood, the cells die, and the tag falls away. This process is known as threading system. Threading System is known for its antimicrobial properties, so the thread will not become infected with potentially infectious bacteria. The ThreadIT Instant Skin Tag Threading System could tie each skin tag as close to the root as possible for a painless cure. The thread is gentle and just strong enough to ensure a tight grip without being uncomfortable. OUR GUARANTEE We are confident that we offer some of the best products on the market.
