The primary mechanism of photo skin aging is mediated by UV induced reactive oxygen species (ROS). ROS damages biomacromolecules and function as intracellular signal to activate transcription factors AP-1 and NF-kB . AP-1 And NF-kB are known to regulate a … Continue reading

UV-induced photo skin aging is primarily mediated via generation of reactive oxygen species/free radicals. Free radical theory of aging and skin aging is one of the most common causes of chronological and photo skin aging. UV irradiation not only activate … Continue reading
Many factors cause wrinkle formation. They are generally classified as intrinsic causes and extrinsic causes: Intrinsic causes of wrinkle include: reactive oxygen species and free radicals – free radical theory of skin aging crosslinking of biomacromolecules by glycation by ROS/free … Continue reading
The study of age-related changes in the physiology, biochemistry, and molecular biology of isolated skin cell populations in culture has expanded and provide the basis for the understanding of the fundamental aspects of skin aging. In the field of molecular … Continue reading
The primary mechanism of UV induced skin aging is the production and generation of reactive oxygen species (ROS). ROS/free radicals is one of the main causes of chronologic and photo skin aging. ROS damages and oxidizes biomacromolecules and cellular components. … Continue reading
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 primary mechanism of UV induced skin aging is the production and generation of reactive oxygen species (ROS). ROS/free radicals is one of the main causes of chronologic and photo skin aging . ROS exerts aging effect via damaging and … Continue reading
The free radical theory of aging established the role of oxidative stress as one of the main causes of aging and skin aging. Reactive oxygen species (ROS) – produced as byproduct of oxidative energy metabolism and induced by external factors … Continue reading
Mitochondria are cellular organelles that produce energy (ATP) by consuming oxygen. In the chronological aging process, mitochondria not only produce less ATP, but they also increase the production of reactive oxygen species (ROS) as by-products of aerobic metabolism, particularly during … 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
