Abstract

Fructobacillus spp. comprise a large genus of fructophilic lactic acid bacteria whose growth characteristics differ from those of other common lactic acid bacteria. The genus has been extensively investigated microbiologically and phylogenetically. However, knowledge regarding Fructobacillus nutritional benefits remains unclear. In particular, Fructobacillus fructosus OS-1010 (OS-1010) was recently shown to act on intestinal cells to release extracellular vesicle exosomes that act on distant target cells. The released exosomes reportedly enhanced the expression of longevity-associated genes and intracellular mitochondrial activity in muscle cells. OS-1010 is expected to be a functional ingredient that improves the function of distant tissues such as muscles and skin upon oral intake. This study examined the effects of the oral intake of heat-killed OS-1010 on human skin in a randomized, double-blind, placebo-controlled, parallel-group study of healthy participants. Significant improvement in skin elasticity was observed after eight weeks of oral OS-1010 intake. Furthermore, although no significant difference was found between the two groups in a wrinkle-related parameter, the OS-1010 group demonstrated improvements in the percentage wrinkle area and overall average wrinkle depth of crow's feet, which were not observed in the placebo group. These results indicate that OS-1010 can contribute to the improvement in skin conditions.
