The BBC reported Sunday that viral videos using the phrase "ferritin face" claim people can see low iron stores in skin, hair and nails, while named doctors said looks cannot diagnose iron deficiency¹.

Clips on TikTok and Instagram list pale or grey-looking skin, dark under-eye circles, dry or cracked lips, hair shedding and weak nails, and some posts show before-and-after portraits, the BBC said¹.

West Midlands GP Dr Aziza Sesay told the BBC, "Ferritin face is not a medical diagnosis," adding it may still be a clue that something is going on¹.

Sesay said pale skin, hair shedding or brittle nails can accompany low iron and can also mark other conditions¹.

Ferritin reflects stored iron; haemoglobin carries oxygen in red cells. Low haemoglobin is anaemia, but iron stores can drop first, so people can be iron-deficient with symptoms and not anaemic, the BBC reported¹.

Consultant haematologist Dr Drew Provan described that split as having no stored iron while haemoglobin is still maintained¹.

Consultant haematologist Dr Sue Pavord said iron deficiency is common and often under-diagnosed in women¹.

UK guidance from the British Society of Gastroenterology, as cited by the BBC, treats ferritin below 15 micrograms per litre as absent iron stores and below 30 as generally low stores¹.

Lucy M, 32, who posts about hair loss as @marvluceskin, told the BBC that in 2021 she had palpitations, fatigue and hair loss; after tests were called normal and she was diagnosed with generalised anxiety disorder, a later test showed ferritin of 12 micrograms per litre¹.

The BBC piece is an explainer built on clinician interviews and one patient's account, not a new clinical trial of whether faces can be scored for iron status¹.

Not medical advice.
