Myths vs facts: Folsäure and Haut

Myth: Folic acid (vitamin B9) is a miracle cure for skin issues like acne, wrinkles, or hyperpigmentation. Fact: Folic acid is essential for cell division and renewal, which theoretically supports skin health. Some studies show modest benefits in UV protection and skin hydration when applied topically or taken orally. However, the evidence is moderate and insufficient to recommend folic acid as a standalone treatment for skin conditions. High oral doses (above 1 mg/day) can mask vitamin B12 deficiency, a risk especially for older adults and vegans. Most skin problems are multifactorial (genetics, hormones, lifestyle), so a balanced diet rich in natural folate (e.g., leafy greens) is more advisable than high-dose supplements. Consumer DNA tests claiming to analyze 'folate metabolism' often lack actionable clinical guidance. Bottom line: Folic acid is no skin miracle, but it can be part of a healthy lifestyle.
