ADH1B encodes an alcohol dehydrogenase enzyme involved in ethanol metabolism. Mechanistically, variants altering enzyme activity could influence acetaldehyde levels, potentially affecting oxidative stress and collagen crosslinking, which might theoretically modulate skin aging. However, robust human studies directly linking ADH1B genotypes to skin aging outcomes (wrinkling, elasticity, pigmentation) are lacking. Most evidence comes from observational studies on alcohol consumption and skin aging, where the genetic contribution is small and inconsistent. Lifestyle factors (UV protection, smoking, diet) overwhelmingly dominate. Direct-to-consumer genetic tests often overstate the clinical significance of such single SNPs.

ADH1B encodes alcohol dehydrogenase, which metabolizes ethanol to acetaldehyde. Certain variants (e.g., rs1229984) increase enzyme activity, leading to rapid acetaldehyde accumulation, causing facial flushing ('Asian flush'). Beyond flushing, acetaldehyde may contribute to oxidative stress and inflammation, potentially affecting skin aging or acne – but these links are based on mechanistic studies and observational data, not robust clinical trials. MyBody-X includes ADH1B in nutrigenetic panels, but its predictive value for specific skin outcomes is limited. A positive result does not guarantee skin issues; lifestyle, diet, and other genes are more influential. Safety note: With a high-activity ADH1B variant, alcohol consumption increases acetaldehyde-related risks (headache, nausea, long-term cancer risk).
