This article describes a membrane-bound enzyme found in skin whose activity increases as biological age increases. The enzyme, located on the external surface of fibroblasts and keratinocytes, generates free radicals. The present work identifies the biological mechanism of the enzyme and its relationship to the appearance of aging in skin.

Multiple factors affect the integrity of cell mitochondria, leading to loss of cell function, aging and apoptosis. In skin, this is expressed in the form of wrinkles, loss of tone, etc. To combat these effects, the author describes a technology that contains mitochondria-nourishing compounds to deliver antiaging benefits.
