Can FUT2 help with Haut?

The FUT2 gene variant determines secretor status and influences gut microbiome composition. Some studies suggest a possible link to skin health (e.g., eczema, acne), but the evidence is weak and mostly mechanistic. There is no robust proof that FUT2 alone has a direct, clinically meaningful effect on skin. Skin health is multifactorial, involving genetics, diet, microbiome, and environment. A genetic test for FUT2 cannot provide specific skin recommendations. Consult a dermatologist for skin concerns.
