Natural and sun-induced aging of human skin.
With worldwide expansion of the aging population, research on age-related pathologies is receiving growing interest. In this review, we discuss current knowledge regarding the decline of skin structure and function induced by the passage of time (chronological aging) and chronic exposure to solar UV irradiation (photoaging). Nearly every aspect of skin biology is affected by aging. The self-ren...
متن کاملAging and Chronic Sun Exposure Cause Distinct Epigenetic Changes in Human Skin
Epigenetic changes are widely considered to play an important role in aging, but experimental evidence to support this hypothesis has been scarce. We have used array-based analysis to determine genome-scale DNA methylation patterns from human skin samples and to investigate the effects of aging, chronic sun exposure, and tissue variation. Our results reveal a high degree of tissue specificity i...
متن کاملMelatonin and human skin aging
Like the whole organism, skin follows the process of aging during life-time. Additional to internal factors, several environmental factors, such as solar radiation, considerably contribute to this process. While fundamental mechanisms regarding skin aging are known, new aspects of anti-aging agents such as melatonin are introduced. Melatonin is a hormone produced in the glandula pinealis that f...
متن کاملA review on nutrition and skin aging
Background: Skin reflects the general health status and is not an exception in the process of aging. Intervention studies indicate that it is possible to delay skin aging and improve skin conditions through diet-based anti-aging strategies. The purpose of the current work was to review recent existing literature regarding the role of nutrition, for and against skin aging processes.Method: This ...
متن کاملEffects of aging on human skin innervation.
To understand the effect of aging on human skin innervation, we investigated intraepidermal nerve fiber (IENF) density of skin biopsies. IENF densities of the distal leg were lower in elderly (> or = 60 years of age) than in young adults (19-39 years of age; 7.80 +/- 0.79 vs 13.55 +/- 0.85 fibers/mm, p < 0.01). A similar trend was also observed in the distal forearm (11.67 +/- 1.55 vs 19.39 +/-...
