Ferritin face: FAQs
What is ferritin face?
Ferritin face is a term that's taken off on TikTok to describe how low iron levels might affect your appearance. People claim it causes dark circles, dull-looking skin and an overall tired appearance (1).
There's some truth to it, but many changes being linked to low ferritin aren't backed by science. And while the photos from content creators might be convincing, you can't tell whether your iron is low just by looking at your face. You’ll need a blood test to find out (1,2).
What is ferritin?
Ferritin is a protein that stores iron in your body, ready for when you need it. Think of it as your body's iron reserve. If your ferritin levels are low, it usually means you are deficient in iron (3).
Your body needs iron to make haemoglobin, a protein in your red blood cells that carries oxygen around your body. If you don't have enough iron, your body may eventually struggle to make enough healthy red blood cells. This can lead to iron deficiency anaemia (2,3).
But you can have iron deficiency without developing anaemia. You may even experience symptoms while your haemoglobin levels are still normal (4).
What counts as low ferritin? British Society of Gastroenterology (BSG) guidelines state that a ferritin level below 30 µg/L generally suggests iron deficiency. Levels below 15 µg/L mean your iron stores are depleted (3).
Where did the ferritin face trend come from?
Ferritin face is the latest in a long line of TikTok wellness trends claiming that changes in your appearance could reveal what's happening inside your body. We've already had “cortisol face”, which links facial puffiness to high stress hormones, and now the spotlight is on your iron levels.
The trend gained traction after a woman shared how her appearance had changed after discovering she had low ferritin and taking iron supplements. The ferritin face before-and-after photos appeared to show brighter skin, less noticeable dark circles and a healthier-looking complexion (1).
Other women began sharing similar experiences, and the idea quickly spread. It reflects a growing interest in finding underlying health explanations for everyday beauty concerns, rather than simply trying ten different skincare products to treat the symptoms.
But while some conditions can affect your appearance, the connection isn't always as straightforward as the internet makes it seem.
What does ferritin face look like and is it real?
There's no medically recognised appearance called “ferritin face”, but people sharing their experiences online often describe similar changes (1):
Dark circles under the eyes that won't go away
Pale, dull or grey-looking skin
Puffy eyes or a swollen-looking face
Dry, cracked lips
Brittle hair or increased hair shedding
There is some truth behind the trend, but not all these changes are signs of low iron.
Pale skin is a recognised symptom of iron deficiency anaemia, which can develop when your iron stores become too low (2). On brown or black skin, paleness may be easier to spot in your gums or inside your lower eyelids than on your face.
Increased hair shedding, particularly in women, and cracks at the corners of your mouth can also occur with iron deficiency, although they have plenty of other possible causes too (2,4). Dry lips generally aren't a reliable sign.
As for dark circles and a puffy face, there's no good evidence that either is a reliable sign of low ferritin. Poor sleep, allergies, genetics and other factors are more common explanations.
Can ferritin face diagnose low iron?
Despite what the internet says, ferritin face cannot diagnose iron deficiency (1,2).
You can have all the signs of ferritin face without having low iron. Dark circles, dull skin and hair shedding have many possible causes. Even if you recognise several of these changes, it doesn't necessarily mean your ferritin is low.
You can also have low ferritin without any visible changes. Iron deficiency doesn't always cause noticeable symptoms, and paleness can be harder to spot on darker skin tones. Looking healthy doesn't necessarily mean your iron levels are normal.
Your appearance can't tell you whether you have anaemia. Some of the signs linked to ferritin face, particularly pale skin, are more closely associated with iron deficiency anaemia than low ferritin alone. You can have low ferritin without being anaemic (3,4).
Rather than judging your iron levels by how your face looks, it's more useful to consider whether you're experiencing other symptoms.
What are the symptoms of iron deficiency?
Symptoms that could point towards low iron levels are usually subtle to begin with and easy to overlook. They include (2,4):
Feeling exhausted or lacking energy
Finding it harder to focus or feeling mentally sluggish
Noticing more hair than usual coming out when washing or brushing it
Having a sore tongue
Getting tired more easily when exercising
Headaches, especially with other symptoms
If your iron levels fall further and you develop iron deficiency anaemia, you may also get out of breath more easily than usual or feel your heart racing or pounding. It is at this point that visible changes associated with “ferritin face”, particularly paler skin, may become more noticeable (2,4).
Not everyone with low iron experiences symptoms, and these changes can have many other causes. But if you're experiencing several together, it's worth checking if your ferritin is low.
How can you check if your ferritin is low?
The only way to know whether your ferritin is low is with a blood test. The best place to start is your GP, who can arrange the appropriate tests to check for iron deficiency and anaemia, such as (2,3):
A full blood count (FBC): Checks your haemoglobin levels and other blood measurements to see whether you have anaemia.
A ferritin blood test: Measures how much iron your body has stored. Your ferritin can be low even when your haemoglobin is normal.
If you'd prefer to do an initial check at home, the Iron Level Test can screen for low ferritin.
It uses a small finger-prick blood sample and gives you a result in around 10 minutes, without needing to send anything to a laboratory. The test checks whether your ferritin is below 20 ng/mL, rather than giving you an exact measurement. A positive result suggests your iron stores may be low (5).
A home screening test doesn't replace a GP blood test. If your result suggests low ferritin, or you have symptoms despite a negative result, speak to your GP for further testing and advice.
Is there a ferritin face treatment?
Some of the changes associated with ferritin face can improve, but there's no single treatment for “ferritin face”. What helps depends on what's causing it.
If your iron levels are low, treating the deficiency may help with pale skin or dark under eyes or hair shedding, though this isn’t guaranteed. This might mean (2,4):
Taking iron supplements to rebuild your iron stores, which may take several months
Eating more iron-rich foods, such as meat, beans, lentils and fortified cereals, alongside vitamin C-rich foods to help with absorption
Treating the underlying cause, such as heavy periods, to prevent further iron loss.
If your iron levels are normal, consider what else might be behind the changes. Dark circles can be linked to genetics, allergies or poor sleep, while puffiness may improve by addressing allergies or getting enough rest. Dry lips may simply need regular lip balm or treatment for irritation.
Hair thinning can have several causes, including stress, hormonal changes and genetics. Depending on the cause, options such as minoxidil may help with female hair loss or male hair loss.
Don't take iron supplements just to improve your appearance without checking whether you need them. Too much iron can be harmful (2).
When should you see your GP?
You don't need to wait until you're looking pale or feeling exhausted to ask about your iron levels.
It's worth booking a GP appointment if:
You're feeling unusually tired despite sleeping well
You’re getting breathless or experiencing heart palpitations
You have heavy periods
You're pregnant or have a condition that makes it harder to absorb iron
You've had low iron before and recognise your symptoms coming back
Your home iron test suggests low ferritin
You have symptoms despite a negative home test result
Your GP can arrange blood tests to check your iron levels and look into what's causing them to drop. Rather than relying on TikTok to tell you what your face might mean, you can get a proper answer and the right treatment if you need it.
