What It Means to Have "Ferritin Face"

At the American Infusion Center’s location on lower Broadway in Manhattan, La-Z-Boy recliners with laptop tables are positioned in front of windows overlooking the Hudson River. The majority of people sitting in those seats—click-clacking away on their computers with an IV dangling from one arm—are women, including me. And many, including me, are there to get an iron infusion—a treatment that, despite being well-informed about my health, I hadn’t even heard of until I was in dire need of it at 47.

My iron levels weren’t ever mentioned at doctor’s visits until I was pregnant with my daughter at 39. With another human growing inside me, the need for adequate nutrients had new urgency. Those levels were steady for the duration of my pregnancy, but after a whirlwind four years—living through a challenging postpartum period, perimenopause, and a global shutdown—they took a nosedive.

But the drop wasn’t something my doctors picked up on easily. It took a year of relentless symptoms (fatigue, hair-shedding, brain fog, restless legs, anxiety), monthly periods reminiscent of crime scenes, and two myomectomy surgeries (to remove clusters of uterine fibroids) before I was deemed anemic. Iron deficiency is the most common cause of anemia, a condition that occurs when your body doesn’t have enough healthy red blood cells. You can be iron deficient (meaning you have low stored iron, or ferritin) but not necessarily anemic, although untreated iron deficiency often leads to anemia.

Though my iron deficiency went largely unrecognized for a time, I’m certainly not alone in this journey, which—like so many diagnoses in women’s health—often follows a long and winding path. A 2024 report from JAMA Open Network found that 34% of women between the ages of 18 and 50 are iron deficient. Post-menopause it becomes less common, as women stop bleeding regularly, so there’s less iron loss; that’s also why iron deficiency is less common in men.

The reason so many women find themselves dealing with anemia, particularly in their 40s (I was 45 when I was diagnosed), is not so straightforward—which is why it comes as no surprise that many are searching for answers and sharing symptoms on TikTok. Ahead, we sort through the signs of iron deficiency, including fatigue, shortness of breath, dark circles, cracking skin, and what social media is calling “ferritin face.”

Iron is a building block for hemoglobin, a protein in your blood that is required for the production of the red blood cells that deliver oxygen throughout our bodies. It sounds vital because it is. It’s key for optimal skeletal and cardiac muscle function, for hair growth, and for making neurotransmitters in our brain (including the dopamine and serotonin that have such a profound effect on our moods), says Imo J. Akpan, MD, a hematologist at New York Presbyterian.

“[Iron] also plays a quieter but important role in supporting regular ovulation and a healthy uterine lining, both of which matter when someone is trying to conceive,” says Lora Shahine, MD, a reproductive endocrinologist and ob-gyn at Ivy Fertility in Seattle.

And iron is foundational to how our bodies produce energy. Explains Amanda Kahn, MD, an internist in New York, “When iron stores are low, women often feel it everywhere, from their energy levels to their mood to their hair.”

Do you have heavy periods? Do you have brain fog? Do you get winded walking up stairs even when you’re in really good physical shape? These are some of the questions Jamie Rosen, a 40-something brand consultant in New York City, remembers being asked by her hematologist Rachel Kramer, MD, during her first visit. “I was like, ‘Yes, yes, yes, yes, yes,’ to everything she asked me,” says Rosen, who had a list of symptoms that she had long been brushing off.

Dr. Kramer has an office at American Infusion Center’s Upper East Side location and has worked as a hematologist for nearly 30 years. She says many of her young, female patients likely have an iron issue that they are chalking up to something else. “Lots of people are iron deficient in their 20s and 30s, and they don’t get to me until they’re in their 40s,” she explains. “They often just think they’re a tired person.”

The most common signs of iron deficiency are: fatigue, headache, shortness of breath, dizziness, chest pain, muscle cramping, pica (the compulsion to eat non-nutritional items such as ice, clay, chalk, or soap), difficulty concentrating, and depression. But this deficiency can also have more visible manifestations, such as hair loss and what the internet has dubbed “ferritin face” or “low-ferritin face.”

Macrene Alexiades, MD, a dermatologist in New York City, says that patients whose iron stores are low often have pale and sometimes dry, cracking, itchy skin. “I see it with some regularity, and when we look under the hood, we often find there’s some iron deficiency there,” says Dr. Alexiades. The washed-out pallor and undereye shadows that sometimes accompany iron deficiency have recently come to be called ferritin face.

“It’s not an established clinical term, but it reflects a real phenomenon that clinicians and patients are noticing,” says Jamie Schwartz, RD, LDN, a registered dietitian at Health Loft. And one that TikTokkers are chronicling in earnest. “I looked literally half dead,” one woman posted about the effect of her ferritin level on her face (with Mumford and Sons’ “White Blank Page” as a soundtrack). "Low iron is looking like this even after 10 hours of sleep and being asked if you're ok 24/7," wrote another, who chronicles her iron struggles online.

While skin pallor and dark circles can be a clue, they are not specific enough on their own to suggest iron deficiency, says Marisa Garshick, MD, a dermatologist based in New York and New Jersey. “Skin pallor is often only noticeable in individuals with lighter skin tones and is not always obvious or easy to detect, while dark circles can occur for many reasons, including genetics,” she points out. That said, “it’s changes in hair and nails that will most commonly prompt an iron work-up in my practice.”

Meanwhile, the connection between hair shedding and ferritin is well documented, with studies associating low ferritin levels with telogen effluvium, a form of temporary hair loss.

Screening for iron levels is not part of a standard checkup. Women are routinely screened only when they’re pregnant, and even then, testing is typically limited to how much iron we have moving in our blood (our serum iron level) and not how much ferritin our bodies are producing. Serum iron levels can go up or down in response to your diet, supplement regimen, or menstrual cycle, and they change quite significantly throughout the day. Ferritin, on the other hand, says Dr. Akpan, refers to our iron reserves and isn’t affected by your diet or periods, and isn’t likely to fluctuate from one day to the next. It’s a much more reliable marker of iron deficiency.

Dr. Akpan describes ferritin as our “iron savings account.” If you’re nearing overdraft, the low balance can have a ripple effect on your body—even if your serum iron level is within normal range. This is why it’s not uncommon for a woman who is noticing hair loss and feels exhausted to still be told by her doctor that her labs are “normal.” Few doctors will do a full iron panel, which includes serum iron and ferritin, as part of a routine visit, so patients often have to request it.

What is considered normal ferritin, though, can be subjective. (Like I said: long and winding.) “We do not have an agreed-upon threshold for diagnosing iron deficiency in women,” says Dr. Akpan. “The World Health Organization recommends using a ferritin cutoff of
