Evidence check: FUT2 in the context of Haut

Evidence for FUT2 in the context of skin health is weak and primarily mechanistic. FUT2 determines secretor status and influences skin microbiome composition, as certain bacteria bind to H antigens on the skin surface. Some studies suggest a link between non-secretor status (inactive FUT2) and increased risk of eczema or dry skin, but results are inconsistent. MyBodyMax DNA tests analyze common SNPs like rs601338, but clinical relevance for personalized skincare is not established. No randomized controlled trials support tailored skincare based on FUT2. Evidence is therefore mechanistic. Caveat: A FUT2 result alone should not prompt changes in skincare or diet without additional biomarkers or medical advice.
