What role does Ferritin play in Haut?

Ferritin is a key iron-storage protein that regulates iron availability and protects against oxidative stress. In the skin, ferritin influences melanin production, collagen synthesis, wound healing, and UV protection. Low ferritin may cause pallor, impaired healing, and photosensitivity; high levels may indicate inflammation or hemochromatosis. The evidence for these roles is based on mechanistic studies and clinical observations, not on the provided context. No direct genetic or biomarker data linking ferritin to skin conditions were supplied. Therefore, ferritin should be interpreted as part of general iron metabolism assessment, not as a standalone skin biomarker. Consumer tests claiming to predict skin health from ferritin-related SNPs lack validation. Clinical evaluation of iron status (serum ferritin, transferrin saturation) remains the standard.
