Of personal interest

I've been noticing certain unwanted age related changes to my skin in the last couple of years:  I'm getting small lumps and brownish patches that never used to be there and would just as soon do without.  So, who knows, a good all purpose aged skin repairing chemical might tempt me to use it:

New work from the University of Maryland suggests that a common, inexpensive and safe chemical could slow the aging of human skin. The researchers found evidence that the chemical—an antioxidant called methylene blue—could slow or reverse several well-known signs of aging when tested in cultured human skin cells and simulated skin tissue.

The study was published online in the journal Scientific Reports on May 30, 2017. "Our work suggests that methylene blue could be a powerful antioxidant for use in skin care products," said Kan Cao, senior author on the study and an associate professor of cell biology and molecular genetics at UMD. "The effects we are seeing are not temporary. Methylene blue appears to make fundamental, long-term changes to skin cells."
