Social Media 'Ferritin Face' Trend: Doctors Say Iron Deficiency Cannot Be Diagnosed by Appearance Alone

A "ferritin face" claim has emerged on social media, alleging that facial features such as pale complexion, dark circles and hair loss can reflect low ferritin, with related videos attracting millions of views. Doctors Aziza Sesay and Drew Provan, interviewed by the BBC, both said iron deficiency cannot be diagnosed by appearance alone, as these features are subjective and unreliable and a blood test is needed for confirmation. British Society of Gastroenterology guidance states that ferritin below 15 micrograms per litre means iron stores are depleted.
