Kimchi for Skin Health

Research suggests that kimchi may offer benefits for skin health, based on its antioxidative properties and the activity of lactic acid bacteria produced during fermentation. A 2014 narrative review highlighted kimchi's broad functional potential, including antioxidative and immune-supporting effects that may indirectly relate to skin health outcomes, while a 2025 systematic narrative review of 125 human clinical studies on ethnic fermented foods found that kimchi and similar foods were associated with improvements across multiple health domains, including skin health specifically. The available evidence is encouraging but should be interpreted with some caution, as the studies are largely reviews synthesizing existing literature rather than controlled trials isolating kimchi's effects on skin outcomes specifically, and more targeted clinical research would strengthen these findings. One study included in the provided sources examined cardiac fibrosis mechanisms and is unrelated to skin health or kimchi, and was not considered in this summary.
