The components of coffee exert multifaceted effects on skin health. Studies have shown that caffeine promotes autophagy and scavenges reactive oxygen species, significantly reducing oxidative stress, thereby delaying skin aging and enhancing skin elasticity. Chlorogenic acid, through its antioxidant and anti-inflammatory properties, inhibits the production of inflammatory factors and mitigates skin inflammation, consequently slowing skin aging and reducing the risk of skin cancer. Ferulic acid, derived from the partial degradation of chlorogenic acid during coffee bean roasting, not only exhibits anti-inflammatory and antioxidant functions but also absorbs and reflects ultraviolet (UV) radiation, helping to reduce UV-induced DNA damage and enhance the skin barrier function. Furthermore, caffeine stimulates the proliferation and migration of skin cells, thereby accelerating wound healing. This article elaborates on the roles and potential mechanisms of coffee consumption in delaying skin aging, preventing skin cancer, providing photoprotection, and promoting skin repair and regeneration, highlighting the significance and potential applications of coffee and its bioactive constituents in promoting skin health.
