Photoaging Decoded: Extracellular Matrix Alterations and Mechanisms via Mitogen-Activated Protein Kinase/Matrix Metalloproteinase, Transforming Growth Factor-β Pathways, and Glycosaminoglycan Metabolism

Abstract excerpt

Photoaged skin features an appearance of premature aging induced by external factors, mainly ultraviolet (UV) irradiation. Visible aging signs and increased susceptibility to skin-related diseases triggered by UV irradiation have raised widespread concern. As a critical component of human skin, the extracellular matrix (ECM) provides essential structural, mechanical, and functional support to the tissue....
