“Forget jade rollers, LED masks and salmon sperm facials,” said nutrition expert Chloe Casey on The Conversation. The “latest skincare trend” is a blood test to detect iron deficiency and avoid the signs of so-called “ferritin face”: dark under-eyes, pale and dry skin, and hair loss.
What is ferritin? Ferritin is a protein that plays a “significant role in the absorption, storage, and release of iron”, said the NHS. It’s found in many types of cells in the body, but especially in the “liver, spleen, bone marrow, and in reticuloendothelial cells”.
Because iron levels naturally “fluctuate throughout the day”, said The Independent, testing ferritin levels is a “better indicator” of iron deficiency problems such as anaemia. You are more likely to suffer from low ferritin and iron levels if you are pregnant or suffer heavy periods. Low levels have also been linked to gastrointestinal problems, diet and poor absorption in the gut.
Is the ‘ferritin face’ discourse harmful? Severe iron deficiency can “make someone look pale”, said Casey on The Conversation. But that doesn’t mean low ferritin levels produce a “distinctive facial appearance”. Other factors such as “hormones, bad sleep, stress, dehydration or not eating enough key nutrients can all leave you looking pale and tired”.
So a “mirror can’t tell you whether your ferritin is low – only a blood test can do that”. But on social media, the “line between medical advice and marketing gets blurry fast”, and warnings about medical conditions often come with links to a “pill or powder” available for purchase.
How can people increase their iron levels? Eat a well-balanced diet including red meat and shellfish, which contain iron that can be “more readily absorbed”, said Grazia. Beans, lentils, chickpeas, tofu, leafy green vegetables and nuts are also rich in iron.
“Taking iron supplements without a diagnosis can be harmful,” said the BBC, and could “delay the investigation of an underlying problem”. Experts advise people at risk of low ferritin to seek a full blood count, including checks for ferritin, B12 and folate levels.
