A social media trend dubbed "ferritin face" claims that low iron levels leave visible clues on the face, such as dark circles and pale or grey-looking skin. Influencers say raising their ferritin levels transformed their complexion, but experts caution that a mirror cannot diagnose iron deficiency – only a blood test can.
What Is Ferritin?
Ferritin is a protein that stores iron in the body, so a ferritin blood test indicates how much iron is in reserve. Unlike iron itself, which fluctuates daily, ferritin is a more stable marker of iron stores. Iron is essential for growth, immune function, energy production, and haemoglobin, the protein that carries oxygen. The body tightly regulates iron levels; running too low risks anaemia, where blood cannot carry enough oxygen.
Who Is at Risk?
Certain groups are more prone to low iron, including pregnant women, people with heavy periods, those with inflammatory bowel diseases, vegetarians, and vegans. Symptoms extend beyond bloodwork: fatigue, weaker immunity, mouth sores, brittle nails, hair loss, and paler skin.
The Truth Behind 'Ferritin Face'
Severe iron deficiency, particularly when it causes anaemia, can make someone look pale. However, low ferritin does not produce a distinctive facial appearance. Hormones, poor sleep, stress, dehydration, or insufficient nutrients can also leave a person looking pale and tired. A blood test remains the only reliable way to confirm low ferritin.
Risks of Iron Supplements
On social media, medical advice often blurs into marketing, with brands suggesting supplements can fix any skin complaint. Excess iron, whether taken at once or accumulated over time, is toxic. Lower doses may cause nausea or diarrhoea; higher doses can lead to dangerously low blood pressure, acid buildup in the blood, and even liver failure.
Getting Iron From Food
If iron levels are genuinely low, diet is a better starting point than supplements. Iron from food comes in two forms: haem iron from red meat, chicken, and fish, which the body absorbs easily, and non-haem iron from lentils, leafy greens, oats, chickpeas, tofu, and fortified cereals, which is absorbed less efficiently. Pairing plant-based iron with vitamin C – such as citrus fruit, peppers, or orange juice – improves absorption, while tea and coffee hinder it and are best kept away from mealtimes.
