On TikTok and other social media platforms, influencers are warning users about "ferritin face." They claim that pale skin, dark circles under the eyes, and dry skin are signs of low iron stores in the body. Ferritin is an essential protein that stores iron, especially in the liver, and releases it when needed. However, medical experts warn that while low iron can affect how you look, a person cannot diagnose the condition from their face alone.
Iron is necessary for every cell in the human body. Sue Pavord, a haematology professor at Oxford University Hospitals, explains that people with low iron often feel very tired, suffer from brain fog, and look pale. Professor Toby Richards from the University of East London notes that visible changes are especially noticeable in patients with severe iron deficiency. However, doctors emphasize that stress, genetics, and dehydration can also cause dark eye circles and tired-looking skin.
Because different health conditions cause similar symptoms, experts urge people not to diagnose themselves online. Iron deficiency is a major health issue and a leading cause of disability in women of reproductive age. Common causes include heavy menstrual periods, pregnancy, plant-based diets, and poor absorption in the gut. Older people with low iron also require medical checks to make sure there is no internal bleeding.
Doctors recommend that anyone worried about low iron should request a blood test from a general practitioner. Professor Richards warns that many over-the-counter supplements do not contain a high enough dose to treat a real medical deficiency. While doctors caution against guessing symptoms from online trends, they welcome the growing awareness, reminding people that constant fatigue should never be ignored.
