Myths vs facts: COMT and skin aging

COMT (catechol-O-methyltransferase) degrades estrogens and catecholamines. Genetic variants like rs4680 (Val158Met) alter enzyme activity: the 'slow' Met variant leads to higher estrogen levels, which may theoretically support collagen synthesis but also increase oxidative stress. Facts: Some association studies link COMT variants to skin aging traits (wrinkling, elasticity), but effect sizes are small and replication inconsistent. A common myth is that a COMT DNA test can dictate a personalized anti-aging regimen. In reality, UV exposure, diet, hormones, and lifestyle are far more influential. Consumer tests often overstate COMT's role. Caveat: Do not base clinical decisions solely on COMT genotype. Evidence: human-moderate to mechanistic.
