How are Ferritin and skin aging related?

The relationship between ferritin and skin aging is indirect and primarily mediated by iron metabolism. Ferritin is the main iron storage protein; low ferritin indicates depleted iron stores, while elevated levels may reflect inflammation or iron overload. Iron is an essential trace element, but excess free iron can promote oxidative stress, damaging collagen and elastin in the skin and contributing to premature aging (photoaging). Conversely, iron deficiency can lead to pale, dry skin and impaired wound healing. However, direct clinical studies specifically linking ferritin to skin aging are scarce. The evidence is largely based on mechanistic reasoning and observational data on iron and oxidative stress. A single ferritin value from a consumer test is insufficient to diagnose skin aging. It should be interpreted in the context of other iron parameters, inflammatory markers, and clinical presentation. If iron deficiency or overload is suspected, medical evaluation with venous blood tests is recommended.
