Description
Photoaging is considered as a group of clinical manifestations due to chronic exposure to solar ultraviolet irradiation (UV). Although it 'spathophysiology is not totally clean reactive oxygen species are known to be generated by UV radiation causing dermic damage, as well as an augmentation in transcription of metallioproteinases (MMPs) due to radiation UV: MMPs produce damage in extracellular matrix and accumulates tissue damage; all that conducing to photoaging Multiple treatments have bemproposed to stop damagingeects UV Amongthem, reducing skin exposure to UV radiation remains as the most importan, followed by the use of antioxidants and treatments which moderate gene expression of MMPs. However, we are only able to diminish photoagingdamage since a specific tmatment to photoaging has not yet been found.
