How are Eisen-Ferritin Selbsttest and skin aging related?

The iron-ferritin self-test measures your body's iron stores. A link to skin aging is mechanistically plausible: excess iron can promote oxidative stress, damaging collagen and elastin – key proteins for youthful skin. Iron deficiency can also impair skin quality (pallor, dryness). However, no validated studies show that self-testing ferritin directly predicts or prevents skin aging. The test is designed as a screening tool for iron status, not a skin aging marker. Evidence is mechanistic/unclear. For skin aging concerns, focus on proven factors: sun protection, diet, sleep, and professional dermatological assessment. A ferritin test alone does not replace a skin evaluation.
