Doctors say ‘ferritin face’ cannot diagnose iron deficiency
Posts on TikTok and Instagram describe pale skin, dark circles and hair changes as ‘ferritin face’, linking them to low iron stores.
Ferritin is a protein that reflects the body’s stored iron, and low iron can cause tiredness and hair loss.
Iron stores can be low even when a person’s haemoglobin is normal, so they may not have anaemia.
Doctors say facial appearance cannot diagnose iron deficiency, and the signs people share online can have other causes.
Blood tests, including ferritin and a full blood count, are needed to assess iron levels.
Doctors advise confirming a deficiency with tests before deciding on treatment.
Iron supplements should be used under a doctor’s guidance, rather than taken without evidence of a need.
Doctors say “ferritin face” is not a medical diagnosis and appearance alone cannot show whether someone has iron deficiency.
The social media trend links signs such as dark circles, pale skin and brittle hair or nails to low ferritin.
Doctors say those signs can have other causes and are not reliable indicators of iron levels.
Blood tests, including ferritin and a full blood count, are needed to assess iron deficiency.
Experts advise confirming a deficiency with tests and planning treatment with a doctor rather than taking iron supplements without advice.
