TLDR Diet and gut health can improve skin, hair, and nails.

Nutritional cosmetology is an interdisciplinary field that examines the impact of diet and gut microbiota on skin, hair, and nail health. This review highlights the gut-skin axis, explaining how dietary components and gut microbiota affect dermatological health through immune modulation and systemic signaling. Probiotics, as live microorganisms, show promise in treating skin conditions like acne and psoriasis and may benefit hair growth and nail integrity. The review discusses probiotic types, mechanisms, clinical applications, and future research, advocating for a holistic approach to beauty that integrates nutrition and dermatology. Personalized and innovative nutritional interventions are expected to improve cosmetic outcomes.
