Is ADH1B useful for skin aging?

The utility of ADH1B for skin aging is not supported by current evidence. ADH1B encodes an alcohol dehydrogenase; while alcohol metabolism can generate oxidative stress potentially affecting skin, no validated human studies directly link specific ADH1B variants to skin aging outcomes like wrinkles, glycation, or collagen loss. Consumer DNA tests such as MyBody-X do not include validated skin aging markers for this gene. Therefore, the evidence level is 'unclear' or 'marketing'. For actionable skin health, focus on proven interventions: sun protection, balanced diet, adequate sleep, and monitoring biomarkers like HbA1c and vitamin D. A genetic test for ADH1B alone does not provide clinically useful guidance for skin aging.
