Can FUT2 help with skin aging?

The provided context does not contain direct evidence linking FUT2 to skin aging. FUT2 encodes a fucosyltransferase that influences blood group antigen secretion and gut microbiome composition. A potential indirect effect on skin aging via the gut-skin axis is mechanistically plausible but lacks robust clinical validation. Current evidence is weak and speculative. Consumers should be cautious about claims that FUT2 variants can guide anti-aging strategies. Lifestyle factors such as diet, sun protection, and sleep have a far greater impact on skin aging than this single gene.
