The viral "ferritin face" trend, which suggests facial features such as pale skin or dark circles can reveal low iron stores, is not a recognised medical diagnosis, doctors have warned. While almost one in three women in the UK (31%) are deficient in iron, experts say only blood tests can confirm the condition.
Iron is essential for making red blood cells that carry oxygen around the body. Symptoms of deficiency include extreme tiredness, shortness of breath, headaches and dizziness, as well as paleness in the skin, inner lower eyelids, gums or nail beds. The "ferritin face" trend claims these signs can be spotted just by looking in the mirror.
Doctors warn against self-diagnosis
Dr Saima Khan, writing on Doctap.co.uk, said "ferritin face" is a social-media trend, not a recognised medical term or diagnosis. She advised: "These changes have several possible causes and cannot confirm iron deficiency. Iron is a mineral the body needs, and ferritin is a protein that stores it."
She added: "Low ferritin can indicate that those stores are running low, sometimes before anaemia develops. Persistent tiredness or changes in your health deserve assessment, but they should not automatically be attributed to low iron."
According to the NHS, iron deficiency anaemia can lead to paler than usual skin, tiredness, breathlessness, noticeable heartbeats and headaches. Dr Khan said pale skin can be a reason to consider anaemia, particularly alongside these symptoms, but it is not enough to make a diagnosis.
What ferritin and iron do
Iron helps the body make haemoglobin, the protein inside red blood cells that carries oxygen from the lungs to the rest of the body. Ferritin stores spare iron so it can be used when needed, and a ferritin blood test shows how much iron is held in reserve.
If the body loses more iron than it takes in, it starts using those reserves. Ferritin can fall while haemoglobin remains normal, a condition called iron deficiency without anaemia. If the shortage continues, there may not be enough iron to make sufficient haemoglobin, leading to iron deficiency anaemia, which means the blood is less able to carry oxygen and can cause tiredness and breathlessness.
Blood tests are the only reliable check
Dr Khan said there is no reliable evidence that "ferritin face" is a distinct condition or that iron treatment reliably changes facial appearance. Dermatologist Dr Geetika Srivastava agreed, noting that iron deficiency can sometimes cause paler skin, dryness or other skin changes, but the only way to know is through "appropriate blood tests and clinical context". She added: "So remember: your face is not a ferritin test."
According to NHS Inform, most people get all the iron they need from their diet, but supplements are sometimes needed. The most common symptoms of iron deficiency anaemia include tiredness and lack of energy, shortness of breath, noticeable heartbeats and a pale complexion. Less common symptoms include headache, tinnitus, an altered sense of taste, itchiness, a sore or abnormally smooth tongue, hair loss, pica, difficulty swallowing, painful ulcers on the corners of the mouth and spoon-shaped nails.
NHS Inform advises people to see their GP if they experience symptoms of iron deficiency anaemia, as the condition can be diagnosed using a simple blood test.
