Can Transferrin help with Haut?

Transferrin is an iron transport protein essential for iron homeostasis. Adequate iron levels are important for skin health, supporting cell turnover, collagen synthesis, and immune defense. However, there is no robust clinical evidence that supplementing with transferrin—either orally or topically—directly improves skin condition. Iron deficiency can lead to pale, dry skin and hair loss, while iron overload promotes oxidative stress and may damage skin. Transferrin itself is not commonly used as a dietary supplement; instead, iron status is assessed via ferritin and other markers. In cosmetics, transferrin is occasionally listed as an ingredient, but independent efficacy studies are lacking. In summary, transferrin is not an established remedy for skin issues. Individuals with skin concerns should consult a healthcare provider to evaluate iron status, inflammation, and other underlying factors. The evidence for a direct benefit of transferrin on skin is currently insufficient.
