What to watch with COMT and skin aging?

COMT (catechol-O-methyltransferase) is key for estrogen and catecholamine breakdown. The common rs4680 (Val158Met) variant alters enzyme activity: the slow Met variant leads to higher estrogen levels, which may theoretically support collagen synthesis but also increase oxidative stress from catechol estrogens. Studies show mixed associations with skin aging (wrinkles, elasticity). Evidence is moderate – mostly observational in women. Lifestyle factors (UV protection, smoking, diet rich in polyphenols from green tea or berries) are more impactful. A DNA test alone has limited predictive value for skin aging. Caveat: no clinical guidelines exist for COMT-based skincare. Combine with biomarkers like vitamin D, collagen metabolites, or skin analysis for a fuller picture.
