Myths vs facts: MTHFR and Haut

MTHFR is a gene encoding an enzyme involved in folate metabolism. Myths often claim that certain MTHFR variants directly cause skin issues like acne, eczema, or premature aging. In reality, the scientific evidence for a direct causal link between MTHFR polymorphisms and skin conditions is weak. Some association studies suggest possible connections to vitiligo or psoriasis, but these are inconsistent and confounded by diet, lifestyle, and environment. Most MTHFR variants are common and have only modest effects on folate metabolism. A direct impact on skin health is not well-established. Consumer DNA tests that analyze these variants often provide exaggerated interpretations. The fact is: a balanced diet rich in folate (e.g., from leafy greens) is more important for skin health than a single genotype. For specific skin concerns, consult a dermatologist rather than a genetic test.
