While up to 40% of aging-related changes in skin are due to non-genetic factors, a recent study found a high correlation between the photodamage scores among both monozygotic (identical) and dizygotic (fraternal) twins.

This article is about something that anyone with teenage children will recognize: the fact that while you cannot get pre-teens to go into the shower, you cannot get teenagers out of the shower. However, when their showering is too often, too hot and too long, they are steam-stripping their skin.

Researchers at the University of California at San Diego have provided a molecular basis to understand the "hygiene hypothesis," the theory that the lack of childhood exposure to infectious agents and microorganisms decreases their susceptibility to disease, which suggests therapeutic approaches to inflammatory skin diseases.

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.
