This is a video review of the No-Pull Piercing Disc, a simple device (a silicone disc) that you add to your jewelry. It is intended to help minimize trauma and discomfort with oral piercings such as lip and tongue. And, from this review, we can see that it is capable of having a huge, positive impact!
You can purchase it here.
After seeing these results, I suggested the innovator of the product do some research about its potential for minimizing scar tissue. As it says in The Piercing Bible section on scar reduction products:
"...ScarEase, ReJuveness, and other silicone sheets, and Biodermis, Kelo-cote, and other silicone gel systems. It isn’t understood exactly how silicone helps scars heal. Some researchers believe that static electricity from the silicone helps align collagen fibers in the scar, while others believe it might help to trap moisture, which can help scars to fade."
