Myths vs facts: Skincare DNA and Haut

Myths vs. facts: Skincare DNA tests often promise personalized routines based on gene variants (e.g., collagen, pigmentation, antioxidant genes). Reality: Some SNPs (like MC1R for skin pigmentation) have known effects, but they are small and overshadowed by lifestyle factors (UV exposure, diet, skincare). Most consumer tests rely on association studies, not clinical validation. A 'skincare DNA test' cannot reliably recommend specific products. Fact: Sunscreen, moisturizing, and healthy habits are evidence-based; gene variants offer only rough hints. Beware of marketing that overstates weak associations into anti-aging claims. Evidence: mixed (GWAS, but no clinical trials).
