IMPACTS OF CHRONIC STRESS ON SKIN HEALTH: NEUROIMMUNE MECHANISMS AND CLINICAL EFFECTS

Abstract

Chronic stress has been shown to have a profound and multifaceted impact on skin health, influencing its integrity and function through complex interactions involving the nervous, immune, and endocrine systems. This systematic review aims to thoroughly investigate how prolonged stress affects skin health, focusing on its inflammatory and regenerative effects. The research was conducted using renowned electronic databases such as PubMed, Scopus, Web of Science, and Embase, and included clinical, experimental, systematic review, and meta-analysis studies published between 2010 and 2024. The findings reveal that chronic stress induces continuous secretion of hormones like cortisol and adrenaline, which adversely affect skin immune function and inflammatory response. This hormonal imbalance results in persistent inflammation, exacerbating existing dermatological conditions such as psoriasis and atopic dermatitis, and contributing to the development of new skin pathologies like acne and alopecia. Chronic stress is also associated with premature skin aging, evidenced by structural damage to collagen and elastic fibers, as well as reduced skin antioxidant capacity. These effects are visible not only in terms of appearance but also in skin functionality, such as delayed wound healing. In addition to direct effects on skin health, the study identifies the potential efficacy of integrative therapeutic approaches that combine dermatological treatments with stress management techniques. Interventions such as cognitive-behavioral therapy and relaxation techniques have shown promising results in mitigating the adverse effects of stress on the skin. However, the review also highlights the urgent need for further research to explore individual variability in stress response, genetic and environmental factors, and long-term efficacy of interventions. Such investigations are crucial for developing more effective and personalized treatment strategies that address both physical and psychological aspects of skin health.
