Probiotics, widely recognised for their benefits in gut health, have gained increasing attention for their comprehensive role in skin health maintenance and improvement. This review explores the multifaceted impact of food-derived probiotics on various aspects of skin health, including anti-aging, inflammation regulation, barrier function enhancement, and hydration. Probiotics exert protective effects against oxidative stress and inflammatory responses through modulation of the gut-skin axis, enhancement of the skin microbiome balance, and immunomodulatory properties. Additionally, functional foods enriched with probiotics have demonstrated efficacy in promoting skin hydration, elasticity, collagen production, and overall resilience. By synthesising recent research findings, this review highlights the potential of probiotic-enriched foods as a natural approach to supporting comprehensive skin health and addressing age-related skin changes. The implications for functional food development and dietary interventions are also discussed, providing insights into future research directions in probiotic-based holistic skin care strategies.
