Aging Skin and Anti-aging Strategies

The skin is a physical barrier that protects our body against various environmental, chemical and agents, the main organ easily visible as time progresses. Aging dynamic, progressive undesirable biological process unfortunately cannot be stopped, according to present knowledge. Intrinsic aging (chronological, spontaneous aging) programmed natural process, while extrinsic (environmental photoaging) associated with sun exposure, smoking malnutrition, which weakens structure functions. Over time, starts lose elastin fibers, collagen other proteins, are basic constituents make healthy, bright, fit elastic. There has been increasing interest in studies on molecular hormonal mechanisms, such hormone dysfunction, changes signaling pathways, downregulation of mitochondrial function cytokine increase, DNA mutation. Antiaging treatment strategies can divided into two parts: primary (basic) preventive antiaging approaches secondary after phenotypic features revealed. study aims review literature information underlying causes aging, healthy protective approaches. Understanding intrinsic pathophysiological processes would increase effectiveness future treatment-finding efforts.
