Common antioxidant could slow symptoms of aging in human skin

May 31, 2017

These cross-section images show three-dimensional human skin models made of living skin cells. Untreated model skin (left panel) shows a thinner dermis layer (black arrow) compared with model skin treated with the antioxidant methylene blue (right panel). A new study suggests that methylene blue could slow or reverse dermal thinning (a sign of aging) and a number of other symptoms of aging in human skin.
