The primary mechanism of UV-induced skin aging is mediated by the generation and accumulation of free radicals including reactive oxygen species (ROS) and reactive nitrogen species (RNS). ROS or free radicals not only can damage proteins, DNA, cellular membrane and … Continue reading

The molecular signaling pathways associated with skin aging is most and initially studied in the photo skin aging. Numerous researches published combined the pieces of discovery into an general overview picture about what occurred molecularly in photo skin aging. It … Continue reading
Many of facial skin aging changes are not the inevitable result of chronologic aging, but with the accumulation of chronic environmental factors. The structural (molecular, cellular), histological changes and the clinical signs associated with intrinsic (chronological aging) and photoaging are … Continue reading
The chronological skin aging is driven by the genetic programming – the programmed aging process that also makes the hair white and makes the teeth fall -. When the natural aging process is superimposed with photodamage, the skin ages much … Continue reading
