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.

MIT and Boston University engineers have designed cells that count cellular events. Such cells could be used to count the number of cell divisions for the study of antiaging; to study a sequence of developmental stages, or to serve as biosensors to count exposures to toxins.

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.

Oregon State University researchers have discovered that the expression of CTIP2 may play a role in some skin disorders. But the research was two-fold, as the team also found the gene to control tooth enamel.
