Can FTO help with Haut?

The question whether FTO (fat mass and obesity-associated gene) can directly help skin is not supported by strong evidence. FTO variants are robustly linked to obesity and BMI, and obesity-related skin issues (e.g., inflammation, cellulite) may indirectly improve with weight management. However, no high-quality studies demonstrate a direct effect of FTO on skin health, collagen synthesis, or aging. Some GWAS hint at weak associations with acne or pigmentation, but effect sizes are tiny and not clinically actionable. The evidence is primarily mechanistic or observational, not from controlled trials. A DNA test for FTO alone cannot provide meaningful skin recommendations. Proven factors like sun protection, diet, and skincare remain paramount. Be cautious of marketing that overstates FTO as a 'skin gene'.
