When I've painted it, I could feel a sting & the sting seemed to be beneath the area as well as right on the surface. So I think the Lugol's sucked out the "bad stuff"
The area scabbed over so I left it alone for a few days and then painted it a few more times. This morning the scab dropped off, no more mole, just fresh new skin:) I also have sporadically painted another area close by for comparison purposes, no change in that area. I believe the Lugol's only targets pre-cancerous or cancerous tissue OR facilitates toxin removal... :)
