What ‘ferritin face’ means — and how to tell if you may be iron-deficient

A low ferritin level doesn't necessarily mean you're anemic, but it could indicate that you have an iron deficiency and are at risk for going down that path.

Social media influencers have a made it a habit of helping people self-diagnose health issues based on their appearance. The latest look they claim reflects an underlying imbalance: “ferritin face.” It describes a set of features that fall under the umbrella of “looking tired” – a dull complexion complete with dry skin, cracked lips and undereye circles – which they say are caused by low iron, and specifically ferritin, a protein that stores iron in the body.

Iron is a mineral involved in many bodily functions, but perhaps its best-known role is in the making of hemoglobin, the protein in red blood cells that transports oxygen from your lungs to the rest of your body. Iron deficiency is the most common cause of anemia, a lack of healthy red blood cells that can leave you tired, weak and short of breath even with routine movement.

A low ferritin level doesn’t necessarily mean you’re anemic, but it could indicate that you have an iron deficiency and are at risk for going down that path.

“Ferritin face” is not a medical term nor is there a consistent set of factors that define it, but it is possible for low iron levels to coincide with visible changes in the face and elsewhere in the body. The trend also capitalizes on a concerning truth about iron deficiency: It’s very common, affecting nearly a third of adults in the United States. Yet, low iron often flies under the radar because symptoms can be vague and come on gradually, and levels are not routinely checked.

Medical organizations do not broadly recommend iron deficiency screening; guidelines from the Centers for Disease Control and Prevention focus on high-risk groups, such as young children and women who are pregnant or of childbearing age.

Even in these groups, iron deficiency can get missed by the typical test. Screening often starts with a complete blood count – a test measuring the number of different cells and proteins such as hemoglobin in the blood – which will only catch people whose iron levels have become so depleted as to cause anemia.

“Because some patients may be iron-deficient without being anemic, they may go on for a very long time without being diagnosed,” said Imo Akpan, a hematologist at NewYork-Presbyterian and associate professor of medicine at Columbia University Irving Medical Center.

To capture the broader swath of people who have low iron without anemia, it’s necessary to check a ferritin level, which is the most accurate measure of your iron reserves, Akpan said. Doctors look at ferritin rather than just iron itself because the amount of iron in the blood fluctuates throughout the day based on what and how recently you’ve eaten, she explained.

We asked experts to break down the potential visual cues and other signs of low iron to be aware of and what to do if you suspect a deficiency – before reaching for a supplement.

The apparent hallmark of ferritin face, a washed-out look, may be more common once iron deficiency has caused anemia. With less hemoglobin and a lower red blood cell count, there will be less oxygen circulating in the blood, Akpan explained, which can make the skin look paler. Because many factors can affect skin tone, paleness of the inside of the lower eyelid (which is usually a pinkish color) or beneath the tongue may be more telltale signs of anemia, said Shannon Dowler, a family physician in North Carolina and member of the board of directors of the American Academy of Family Physicians.

Iron deficiency can also result in other physical changes because “iron is important for cells with what we call a really high turnover,” Akpan said, meaning they die and are replaced quickly. Skin cells fall into this camp. Without enough iron to support cell regrowth, skin can become thin and dry, making undereye circles more visible and leading to cracking in the corners of the mouth, Akpan said.

Low iron can also cause hair breakage as well as brittle, slower-growing nails, said Doris Day, a dermatologist in New York City and clinical professor of dermatology at the New York University Langone Medical Center.

But as Dowler pointed out, these visual symptoms aren’t usually the first or only signs of iron depletion – it typically affects how you feel, too. In her practice, the most common complaints among those with iron deficiency are fatigue and exercise intolerance, which people may describe as feeling like their heart is pounding or beating rapidly when they exercise.

Other symptoms include shortness of breath with light activity, dizziness, headaches, cold hands and feet, brain fog, craving non-nutritious items like ice, soap or chalk, as well as trouble sleeping (some people can develop restless leg syndrome) and low mood, Akpan said.

But these can be subtle and develop slowly. It might not be until people start to see changes in their appearance that they choose to seek care, which is why dermatologists can sometimes be first to check for low iron. “They may come in complaining of hair loss or that they feel or look tired, different or older,” Day said. “Then I’ll start asking other questions and put it together.”

It’s important to see your primary care doctor or a dermatologist if the bulk of your symptoms relate to your skin, hair or nails. One reason is because all of the signs above can also point to other conditions, not just low iron. Taking iron supplements without knowing if you need them risks leaving the real problem untreated and causing toxicity, Dowler said. Overloading on the mineral can cause severe damage to the digestive tract and even be fatal.

Every expert we spoke to mentioned that thyroid disorders can be easily confused with low iron. “A thyroid deficiency can cause very similar symptoms, such as dry skin, hair loss, tiredness and lack of energy,” said Judith Hellman, a dermatologist in New York City and associate clinical professor of dermatology at Mount Sinai. The same goes for certain autoimmune conditions, Akpan noted, such as Sjögren’s syndrome (in which the immune system attacks the body’s moisture-producing glands). Then there’s the possible culprit of perimenopause, Day said, which can result in the same type of skin and hair changes.

Bloodwork is the only way to know if you’re iron-deficient. The workup often includes a ferritin test – levels lower than 30 nanograms per millilitre point to deficiency – as well as a test for total iron-binding capacity (a measure of your blood’s ability to transport iron) and a complete blood count to screen for anemia. If your doctor is suspicious of other issues, they can also check your thyroid-stimulating hormone and vitamin levels, for instance, at the same time.

Even if you find out that you have low iron, seeing a doctor is key to determining why. While it can be tied to simply not eating enough iron-rich foods, it could also be the effect of an underlying condition that impairs iron absorption such as Celiac disease or inflammatory bowel disease, Akpan said. People who take popular heartburn medications, such as omeprazole, for an extended period are also at higher risk of iron deficiency, she added. And in rare cases, low iron can be the result of a gastrointestinal issue causing blood loss, such as colon cancer.

The best way to replenish iron depends on why it’s low and the extent of deficiency. If you’re borderline, for instance, you might be able to reach a healthy level by doubling down on iron-packed foods, Dowler said, such as red meat, spinach, beans and iron-fortified cereals.

People with a larger deficit may need iron supplements, which can be tricky to take correctly, Akpan said – they have to be spaced out from items with caffeine and calcium, and from antacids. They’re also well-known to trigger GI side effects such as constipation.

Iron infusions may be necessary in those with a major deficiency, people who can’t keep up with or tolerate the oral tablets and pregnant people (who need to restore iron levels quickly), Akpan said. And they’re also more effective in those who have an underlying condition affecting absorption, she said, since IV iron circumvents the GI system and goes straight into the blood.

These considerations add to the importance of “seeking a professional to guide you the right way,” Hellman said. “Ferritin face” may be helping to raise awareness about iron deficiency. “But people should know not to diagnose and treat themselves by TikTok clips,” she said.
