ACTUALLY, when I left them alone, they went yellow, and looked rotten for a while. People, friends, family all stared. It was awful. That last for about two years. I used scissors to cut away the dead parts that lifted off. Maybe a couple times Id use natural beeswax balm to moisten it so it wouldnt look to bad if i were going to a social function.
Remember, it did not happen over night. This was a yearly process. Then, at the same time I tried many procedures including bioposy, surgical removal, laser treatment, cancer cream, etc... This is all in my posts. I believe everything helped in the long run.
