Is MY FOODBOOK useful for skin aging?

Whether MY FOODBOOK is useful for skin aging cannot be answered with strong evidence. The product offers personalized nutrition based on genetic testing, but the evidence for a measurable benefit specifically for skin aging is weak. General research on genotype-matched diets (e.g., PMID 37813841, PMID 38474735) shows that single-gene effects are small and lifestyle factors dominate. Skin aging is primarily driven by UV exposure, smoking, sleep, and overall diet quality – not by individual SNPs. No randomized controlled trials demonstrate that a DNA-based dietary plan significantly slows skin aging. While mechanisms like collagen synthesis and antioxidant capacity are biologically plausible, translation into real-world outcomes remains speculative. Long-term data are lacking. Consumers should be cautious: marketing claims often outpace the science. A healthy lifestyle with sun protection, adequate sleep, and an antioxidant-rich diet remains the only evidence-based approach to combat skin aging. MY FOODBOOK may serve as supplementary inspiration but does not replace dermatological or nutritional counseling.
