The document reviewed the complex phenomenon of skin aging, identifying it as a degenerative disease influenced by intrinsic and environmental factors, leading to issues like atrophy, fragility, defective repair, and reduced immunity. It highlighted the roles of stem cell dysfunction and genetic and epigenetic factors in skin aging, which also affected the microbiome and cancer development. Key changes in aged skin included altered keratinocyte and melanocyte distribution, reduced collagen and elastin, fibroblast structural changes, and increased matrix metalloproteinases, contributing to collagen breakdown. Aged skin also showed reduced immune function and increased susceptibility to infections. The review emphasized the need for future research to develop strategies to mitigate skin aging effects and improve public health strategies.
