Causal effects of circulating metabolome on facial skin aging in the secondary analyses. A Volcano plot showing the causal estimates of 123 metabolic traits on facial skin aging in the secondary analyses with IVW method; B forest plots showing the causal estimates of seven metabolic traits that are significantly associated with facial skin aging in the secondary analyses with IVW, MR-Egger, and weighted median methods. MR, Mendelian randomization; IVW, inverse-variance weighted, No., number; SNP, single-nucleotide polymorphism; CI, confidence interval
