UV-Induced Neutrophil Infiltration and Increased MMP Secretion in Photo Skin Aging

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

The Endogenous Photoprotective Mechanisms In The Skin

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
