There seems to be quite a controversy surrounding a man named Paul Karason, nicknamed “The Blue Man” whose skin has turned a purple-blue. The media has covered the story, claiming that it was caused by him consuming and topically applying Colloidal Silver to his skin. Apparently Paul decided to make a homemade concoction that he thought was colloidal silver, but was not colloidal silver. He created a dangerous, toxic substance called ionic silver by mistake. His resulting consumption of the homemade concoction caused him to develop a skin condition called argyria that makes the skin turn a blue-gray color. Apparently there is no cure for argyria, so he has to live the rest of his life as a blue man.
Even though his homemade concoction turned his skin blue, he continues to use it, so he must not be too upset about the situation!
