Myths vs facts: Folsäure and skin aging

A common myth is that folic acid (or folate) can prevent skin aging or reduce wrinkles. The scientific evidence for a direct anti-aging effect on skin is weak. Folate is a B-vitamin essential for DNA synthesis, repair, and methylation – processes that could theoretically influence skin health. Some observational studies suggest a link between low folate levels and increased skin aging, but randomized controlled trials are lacking. Importantly, synthetic folic acid (in supplements) is metabolized differently than natural folate from food. High doses of folic acid may even have adverse effects, such as masking vitamin B12 deficiency. For those seeking to slow skin aging, a healthy lifestyle with balanced nutrition, sun protection, and adequate hydration is more evidence-based. Genetic testing for MTHFR variants (as offered by MyBody-X) may relate to folate metabolism, but its relevance to skin aging is unclear. Bottom line: Folic acid is not a miracle anti-aging compound; the evidence is mostly mechanistic and insufficient to recommend it for skin aging prevention.
