Doctors say 'ferritin face' trend cannot diagnose low iron

Videos on TikTok and Instagram claim low ferritin, a protein that stores iron, shows up as pale skin, dark circles, dry lips and brittle hair, dubbed 'ferritin face'. Doctors say appearance alone cannot diagnose iron deficiency. "Ferritin face is not a medical diagnosis," said GP Dr Aziza Sesay, adding such signs may only be a clue that something is wrong.
