The relationship between skincare DNA and weight loss (Abnehmen) is indirect and supported by limited evidence. Skincare DNA tests examine genes related to collagen breakdown, antioxidant defense, and inflammation (e.g., COL1A1, SOD2, GSTP1). Weight loss genetics focus on energy metabolism, appetite, and fat storage (e.g., FTO, MC4R, PPARG). Some genes like PPARGC1A or ADRB2 may influence both oxidative stress and mitochondrial function, but effect sizes are small. MyBody-X offers separate skin and weight analyses; combining them provides a broader picture but no causal link. Evidence is mostly exploratory (GWAS, small effects). No clinical conclusions can be drawn. Caveat: DNA tests cannot replace blood biomarkers or medical advice. Lifestyle factors (diet, sun protection, exercise) dominate both domains.
