Stork bite is a common, harmless birthmark made of small widened blood vessels near the skin. It is usually seen at birth on the back of the neck, eyelids, forehead, or nose. The main features of stork bite are flat pink or red patches that may look darker when a baby cries or gets warm, which are common signs of a stork bite. Not everyone will have the same experience, but many stork bite marks on the face fade in early childhood while patches on the neck often last into adult life. Stork bite does not affect lifespan, and treatment is often not needed, though laser treatment can help if a lasting mark is bothersome.
How many people live with Stork bite?
Direct worldwide and U.S. counts of everyone living with a stork bite are not routinely reported, so estimates are usually based on how often it is seen in newborns. Using a widely cited estimate that stork bite is present in about 44% of babies at birth, that works out to roughly 62 million babies worldwide each year (UNICEF, 2024; StatPearls, 2023) and about 1.6 million babies in the United States each year (CDC National Center for Health Statistics, 2024; StatPearls, 2023).
Overview
Stork biteSymptoms
Stork bite is a common flat pink or red birthmark, often on the back of the neck, eyelids, forehead, or nose. It is usually present at birth. These marks are painless and may look more noticeable with crying or temperature changes.
Outlook and prognosis
Stork bite is harmless and does not affect growth, learning, or overall health. Many fade during infancy and early childhood, especially on the face, while marks on the back of the neck often stay into adulthood but usually remain mild.
Causes and risk factors
Stork bite is a common birthmark caused by tiny surface blood vessels staying widened before birth. The exact reason is usually unknown, and it is not linked to anything parents did during pregnancy. No clear lifestyle or environmental risk factors are known.
Genetic influences
Genetics do not seem to play a major role in stork bite for most people. Stork bite is usually not inherited, though it can occasionally appear in more than one family member.
Diagnosis
Diagnosis of Stork bite is usually made during a routine exam by looking at its typical clinical features. Tests are rarely needed, but a dermatologist may check closely if the appearance is unusual.
Treatment and drugs
Stork bite is usually harmless and often fades on its own, especially on the face. Most babies do not need treatment, and care is mainly watchful waiting during routine checkups. Marks on the neck may last longer but rarely need treatment.
Symptoms
Parents often first notice the early features of Stork bite as a flat pink or red patch on a newborn's skin. For many people with Stork bite, it appears on the back of the neck, eyelids, forehead, or around the nose and does not cause pain or itching. The color can look stronger when a baby cries, gets warm, or strains. Many marks on the face fade over the first few years, while ones on the neck often last longer.
A stork bite is usually a flat, smooth area of pink, red, or salmon-colored skin. It is not a bump, sore, or rash, and the skin texture stays normal.
These birthmarks often show up on the back of the neck, eyelids, forehead, or between the eyes. Some may also appear around the nose, and more than one area can be involved.
The patch may look darker when a baby cries, has a bath, gets hot, or strains. When the skin is calm and cool, it often looks lighter again.
Stork bite does not usually hurt, itch, bleed, or interfere with feeding, sleep, or movement. For many families, it is mainly a cosmetic finding rather than a medical problem.
How people usually first notice Stork bite?
Stork bite is usually first noticed at birth or soon after as a flat pink or red patch on the skin, most often on the back of the neck, eyelids, forehead, nose, or upper lip. The first signs of stork bite are soft, faint marks that often become easier to see when a baby cries, feels warm, or strains, because the tiny blood vessels in that area widen. For many families, how stork bite is first noticed is simply during a newborn exam or while cuddling and bathing the baby, and these marks are common and harmless.
Types of Stork bite
No distinct types of Stork bite are widely recognized.
Can I slow down the onset of symptoms?
No. A stork bite is a common, harmless pink birthmark that is usually there at birth or shows up very soon after, so there is no known lifestyle change, medicine, or other treatment that can delay it from appearing, and it does not usually cause symptoms. There are no established screening or preventive treatments for stork bites, but many fade on their own over time, even though ones on the back of the neck often stay.
What genetics can tell you about symptoms
For most people with a stork bite, genetics does not tell us much about symptoms because this common birthmark is usually a harmless variation in tiny blood vessels rather than a condition with a clear inherited pattern. It does not usually cause symptoms, and known genetic differences have not been shown to reliably predict where it appears, how noticeable it is, or whether it fades over time. In most babies, the main difference is simply location and how long the color lasts, not a gene-driven change in severity or age of onset.
Causes and risk factors
Many parents wonder what causes a stork bite birthmark when they first see a pink patch on a baby's neck or eyelids. A stork bite usually happens because tiny blood vessels near the skin stay widened during development before birth. It is not usually linked to an inherited gene change, and most babies with a stork bite have no family history of it. Doctors do not know of any clear lifestyle or environmental risk factors, so it is not thought to be caused by something a parent did during pregnancy. Researchers are still learning how these pieces fit together, but in most cases there is no known way to prevent it.
What are the most common causes or risk factors?
A stork bite is usually not caused by anything a parent did during pregnancy. It happens when tiny blood vessels near the surface of a baby's skin stay a little wider than usual before birth, which creates a flat pink or red mark. The main risk factor is simply being a newborn, because these marks are very common and are not usually linked to family history, medicines, foods, or other health problems.
Environmental and biological risk factors
Stork bite is a very common birthmark seen at birth, and most of the time there is no clear reason why one baby has it and another does not. Doctors often group risks into internal (biological) and external (environmental). For stork bite, well-proven risk factors are limited, and current evidence points more to a harmless difference in early blood vessel development than to a specific exposure or health problem.
A stork bite is thought to happen when tiny blood vessels near the skin stay a little wider than usual before or around birth. This makes it more of a common biological variation than a birthmark with a clearly defined medical risk factor.
Researchers have not identified specific environmental exposures that consistently increase the chance of a stork bite. In most babies, it is not linked to a known outside cause during pregnancy or delivery.
Genetic risk factors
For most people with a stork bite, the mark appears without a clear genetic cause. Researchers have not found one specific gene that explains the usual neck or forehead patch, and many cases seem to happen by chance before birth. In some families, these marks show up in more than one relative, which suggests a mild inherited tendency in at least some cases. If you are wondering about the genetic causes of stork bite, the main point is that a typical isolated mark is usually not linked to a broader genetic disorder.
Sporadic cases: Most stork bites happen in babies with no known family history. This means the usual mark often appears by chance rather than from a single inherited gene.
Family history: Stork bites can run in some families. When close relatives have similar marks, inherited factors may slightly raise the chance, but the pattern is not strong or predictable.
No single gene: Researchers have not identified one gene that causes most typical stork bites. For many people with a stork bite, genetic testing is not needed because the mark is usually isolated and harmless.
Rare syndromes: In uncommon situations, a vascular birthmark may appear as one part of a genetic syndrome. Still, a classic stork bite on the back of the neck or between the eyebrows by itself usually does not suggest an inherited condition.
Lifestyle risk factors
A stork bite is present from birth, so lifestyle habits do not cause it. In most children it fades with time, but certain day-to-day factors can make the area look redder or become more irritated. When people ask how lifestyle affects Stork bite, the main issues are temporary flushing, friction, and skin care rather than true disease progression.
Too much sun can make the pink or red color stand out more against surrounding skin. Sunburn can also irritate the area and make it look more inflamed for a time.
Hot weather, very warm baths, vigorous exercise, or emotional stress can increase blood flow near the skin and make a stork bite appear darker temporarily. This does not usually mean the mark is worsening, but it can make it more noticeable.
Tight collars, rough fabrics, hats, or repeated rubbing can irritate a stork bite on the neck, scalp, or forehead. Irritation may lead to extra redness and sensitivity, especially in babies and young children.
Fragranced soaps, strong cleansers, and irritating hair or skin products can dry or inflame the skin over the birthmark. Gentle skin care may help reduce redness and discomfort in that area.
Risk prevention
A stork bite is a very common birthmark that is present from birth, so there is no proven way to prevent the mark itself from happening. For most babies, a stork bite is harmless and often fades with time, especially on the face, while marks on the neck may last longer. Prevention is mostly about avoiding skin irritation, protecting the area, and knowing when a mark may not fit the usual pattern. Different people need different prevention strategies—there’s no single formula.
A stork bite usually does not need treatment, but gentle washing and fragrance-free skin products can help prevent dryness or irritation. This matters most if the mark sits where clothing, bibs, or collars rub often.
If a stork bite is on the face or scalp, protecting the skin from too much sun can help prevent extra redness and irritation. Use shade, hats, and age-appropriate sunscreen when a clinician says sunscreen is suitable.
Repeated rubbing can make a stork bite look more noticeable for a while and may irritate sensitive skin. Soft fabrics and loose-fitting clothes can help reduce this.
A typical stork bite stays flat and does not cause pain, bleeding, or sores. If you are worried about early symptoms of stork bite getting worse, or the mark becomes raised, darker, or very one-sided, it is worth having a doctor check that it is truly a stork bite and not a different birthmark.
Can you prevent Stork bite?
No, stork bites cannot be prevented. They are very common, harmless birthmarks that develop before birth when tiny blood vessels near the skin stay a little wider than usual, and they are not caused by anything a parent did or did not do during pregnancy.
Transmission
A Stork bite is not infectious at all, so it cannot be caught from someone else through touch, kissing, blood, or everyday close contact. It usually forms before birth when tiny blood vessels near the skin stay more open than usual, and in most cases there is no clear genetic transmission of Stork bite.
If you are wondering how Stork bite is inherited, the answer is that it usually does not follow a known parent-to-child pattern. Parents do not cause it, and having one baby with a Stork bite does not usually mean another child will have the same mark.
When to test your genes
For a stork bite, genetic testing is usually not needed. This common birthmark is typically harmless, not linked to a known inherited disorder, and is usually diagnosed just by looking at it. Testing may be considered only if there are unusual features or other medical concerns alongside it.
Diagnosis
Stork bite is usually diagnosed by its appearance on the skin, often soon after birth or during a routine baby checkup. These flat pink or red patches are common on the back of the neck, eyelids, forehead, or between the eyebrows, and they often become more noticeable when a baby cries or gets warm. In most cases, the diagnosis of stork bite does not require complex testing because the location and look are so typical.
Doctors usually diagnose a stork bite by looking closely at the patch and noting its color, flat surface, and typical location. The mark often blanches, meaning it briefly fades when gentle pressure is applied.
A routine newborn exam and a brief health history can help confirm that the mark has been present since birth and has behaved in the usual way over time. This helps separate a stork bite from skin changes that appear later for other reasons.
The genetic diagnosis of stork bite is generally not needed because this mark is usually identified from its classic pattern rather than from lab findings. Patches on the eyelids, forehead, or back of the neck strongly support the diagnosis when they match the usual appearance.
If the patch looks unusual, is much darker, one-sided, raised, or does not fit the expected pattern, your provider may suggest a dermatology review to look closer. In some cases, specialist referral is the logical next step to rule out a different kind of birthmark.
How is Stork bite diagnosed?
A stork bite is usually diagnosed during a regular skin exam by its typical look and where it appears, most often on the back of the neck, eyelids, forehead, or between the eyebrows. Doctors can usually tell it apart from other birthmarks because it is flat, pink or red, and often becomes more noticeable when a baby cries or gets warm. Tests are not usually needed, but if the mark looks unusual, is only on one side, or does not fade as expected, a doctor may check more closely to rule out a different kind of birthmark.
Stages of Stork bite
Stork bite does not have defined progression stages. This is because it is a common flat pink or red birthmark that does not usually worsen over time, and in many babies it fades gradually as they grow. Doctors usually start with a conversation about when the mark was first seen and whether it changes with crying, temperature, or pressure. A stork bite in babies is usually diagnosed by its typical look and location, often on the back of the neck, eyelids, forehead, or between the eyebrows, and it is usually just watched over time during routine checkups.
Outlook and prognosis
The outlook for a stork bite is excellent, because it is a harmless birthmark that usually fades on its own over time. Marks on the eyelids, forehead, or between the eyes often become much less visible in early childhood, while those on the back of the neck may persist longer or into adulthood without causing health problems. A stork bite does not turn into skin cancer, does not affect development, and is not linked to reduced life expectancy. Mortality is not increased, as this finding is benign and not life-threatening. If the mark looks unusual, becomes raised, or is associated with other symptoms, a clinician may check for a different type of vascular birthmark rather than a true stork bite.
Long-term effects
For many living with stork bite, the long-term picture is usually mild and mainly cosmetic. These flat pink or red patches often become much less noticeable as a child grows, especially on the forehead, eyelids, or nose. In medical terms, these are sometimes called late effects or chronic symptoms, but with stork bite they are usually ongoing skin features rather than signs of illness. One of the most common questions is do stork bites go away, and the answer is often yes for facial marks, while patches on the back of the neck are more likely to remain.
Many stork bite marks lighten naturally during infancy and early childhood. For many, facial patches are faint or no longer easy to see by the time they reach school age.
Stork bite on the back of the neck often lasts longer than marks on the face. In many people, it remains into the teen years or adulthood, though it is usually covered by hair and stays harmless.
The color may look stronger when a child cries, gets warm, or strains. This can continue over time, but it does not usually mean the mark is worsening or causing damage.
A stork bite does not usually lead to skin disease, pain, bleeding, or problems with growth and development. It is a benign birthmark, so the long-term effect is most often simply a visible patch of skin color.
How is it to live with Stork bite?
Living with a stork bite usually has little to no effect on daily life, because it is a common, harmless birthmark made of small blood vessels close to the skin. Many fade on their own over time, especially on the face, while patches on the back of the neck often remain but are usually hidden by hair and do not cause pain, itching, or health problems. For families, the main impact is often emotional rather than medical, since other people may notice the mark and ask questions, but reassurance helps: this is not contagious, not caused by anything a parent did, and in most cases does not limit a child in any way.
Treatment and drugs
A stork bite is a common flat pink or red birthmark, and in most babies it does not need treatment because it often fades on its own over the first few years of life, especially on the face. Marks on the back of the neck can last longer and may stay into adulthood, but they are harmless and do not turn into skin cancer or a more serious blood vessel problem. Treatment often looks different for each person, but for the small number of people who want treatment for a stork bite that remains visible, a skin specialist may discuss laser treatment to lighten the color. If you are worried about early symptoms of stork bite or a mark seems raised, rapidly changing, or different from a typical flat patch, it is worth having a doctor check it to confirm the diagnosis.
Can you cure Stork bite?
A stork bite does not need a cure, because it is a harmless birthmark and not an illness. Many fade a lot on their own in early childhood, although ones on the back of the neck often last into adult life. If one stays and its appearance bothers someone, treatment such as a laser can sometimes lighten it, but treatment is usually not needed.
Non-drug treatment
A stork bite is a common flat pink or red birthmark that often fades on its own, so treatment is usually not needed. Managing this condition often means simple observation and reassurance, especially in the first months or years of life. Most families asking how to treat a stork bite birthmark are really deciding whether to watch and wait or consider treatment later if a mark stays visible. When a stork bite lasts on the face or causes cosmetic concern, a skin specialist may discuss laser treatment.
Most stork bites become lighter over time, especially those on the eyelids, forehead, or around the nose. Regular check-ins during routine visits are often enough unless the mark changes in an unusual way.
A stork bite does not usually hurt, itch, or affect a child’s health. For many families, clear information about what to expect is the most helpful non-drug care.
The skin over a stork bite can usually be washed and moisturized like the surrounding skin. There is no special cream, massage, or home treatment proven to make it fade faster.
Sun exposure can make a stork bite look more noticeable for a while, especially on lighter skin. Hats, shade, and child-safe sunscreen when age-appropriate can help the color appear less prominent.
Your genes may have an impact on how drugs work for you
Stork bites are very common birthmarks that usually do not need any medicine, so inherited differences in how your body handles drugs are generally not an important part of care here. Most fade on their own, especially on the face, and treatment is rarely needed unless the mark is being checked because it looks unusual or seems to be part of a different skin problem. In other words, for people with a simple stork bite, genes usually do not affect medication choices because medications are not commonly used for this condition.
Pharmacological treatments
Stork bite is usually harmless and most often fades on its own, so medicine is not a standard treatment. Medication can feel like a big step, but for this birthmark, doctors usually do not prescribe drugs because they do not make the mark go away. For many families asking about treatment for stork bite birthmark, the main approach is watchful waiting and simple skin care if needed.
There are no standard medicines used to treat a stork bite itself. Most salmon patches on the eyelids, forehead, or back of the neck improve with time without tablets, syrups, or injections.
Medicated creams, steroid creams, and antibiotic ointments are not used to fade a stork bite unless there is a separate skin problem. If the skin becomes irritated for another reason, a doctor may suggest treatment for that irritation, not for the birthmark.
If a stork bite persists in a visible area and is bothersome, pulsed dye laser may sometimes be discussed. This is a procedure rather than a drug treatment, and many people with stork bite never need it.
Genetic influences
When a newborn has a stork bite, many parents wonder what caused it and whether it runs in the family. It’s natural to ask whether family history plays a role, but for most babies with a stork bite, genetics does not seem to be the main reason it appears. Researchers have not linked stork bite to one specific inherited gene change, and it is usually seen as a very common, non-inherited birthmark. Instead, it is thought to happen because tiny blood vessels near the skin stay a little wider and more visible around birth. For many, this can mean a faint pink patch on the neck, eyelids, or forehead that becomes more noticeable with crying or warmth, then often fades with time. If a mark looks unusual, affects only one side, or comes with other findings, doctors may check whether it is a different kind of birthmark, because some vascular skin conditions can have a stronger genetic link.
Is Stork bite genetic?
Genetics do not seem to play a major role in stork bite for most people. Stork bite is usually not inherited, though it can occasionally appear in more than one family member.
Having a genetic risk is not necessarily a diagnosis
Differences in genes are a normal part of being human, and they are widespread across the population. Most do not directly affect health and simply reflect the natural differences seen among people. For many genes, having a variant linked to a condition suggests a possible connection rather than a firm diagnosis, especially when several genes and environmental factors are involved. Still, in some cases, one well-understood variant in a specific gene can be enough on its own to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For most babies with a stork bite, genetics do not change treatment very much because these marks usually fade on their own and rarely need medicine. There are no standard drugs used to treat a stork bite, so pharmacogenetic testing, which looks at how genes affect medication response, is not usually part of care. Genetics is only one factor, and for stork bite the bigger questions are where the mark is, how noticeable it remains over time, and whether it causes cosmetic concern later on. If a mark stays visible and a family is considering laser treatment for a stork bite birthmark, doctors usually base that decision on the child’s age, skin tone, and the look of the mark rather than on genetic test results. Although some vascular birthmarks can be tied to specific genetic changes, a typical stork bite is usually managed with watchful waiting and, if needed, laser treatment rather than gene-guided medication choices.
Interactions with other conditions
Most stork bites are harmless birthmarks, and on their own they usually do not interact with other diseases or cause other health problems. For many living with a stork bite, this means the mark may simply be more noticeable when a baby cries, gets warm, or strains, without signaling an illness underneath. In most cases, a stork bite is not linked to skin cancer, infection, or problems with brain development, and it does not usually change how other conditions are treated. The main exception is when a pink or red mark does not behave like a typical stork bite, such as being only on one side, becoming darker or thicker over time, or appearing with other unusual skin findings, because that can point to a different kind of birthmark that may need a closer look. The presence of another illness does not always mean the birthmark is related, but if there are concerns about early symptoms of skin conditions or a mark that seems to be changing, a pediatrician or dermatologist can help confirm whether it is truly a stork bite.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Stork bite?
Other birthmarks can look similar to a stork bite, especially port-wine stains, which are flat pink or red patches that usually do not fade over time, and hemangiomas, which are often called strawberry marks and tend to grow thicker or more raised after birth. In some babies, a mild rash or temporary skin redness can also be mistaken for a stork bite at first. A doctor can usually tell the difference by looking at the color, shape, whether the mark is flat or raised, and how it changes over time.
History
Parents have likely been noticing these soft pink marks on newborn skin for as long as babies have been born. Across cultures and time periods, stork bite has picked up gentle everyday names, often tied to where the mark appears or to folklore about how a baby arrived. Many families still hear terms like “angel kiss” for marks on the forehead or eyelids and “stork bite” for marks on the back of the neck.
For a long time, these marks were simply described by how they looked: flat, pink, and more noticeable when a baby cried, strained, or got warm. Early medical writing grouped several kinds of birthmarks together, so stork bite was not always clearly separated from other red or purple skin marks. This meant some parents got confusing information, especially when one type of birthmark could fade on its own while another might need closer follow-up.
As medical science evolved, doctors became better at telling common harmless marks apart from less common vascular birthmarks. Stork bite came to be recognized as a very common capillary birthmark, often called a salmon patch or nevus simplex in medical settings. That change mattered in daily life: instead of hearing a vague description, families could be reassured that these marks are usually benign and often fade over time, especially when they are on the face.
Over the past century, newborn exams and pediatric care helped standardize how stork bite is described and recorded. Doctors also learned that location matters. A pink patch on the eyelids or forehead often becomes much lighter in early childhood, while a mark on the back of the neck may last longer, sometimes into adult life, hidden under the hair and causing no symptoms at all.
Today, the history of stork bite is less about dramatic medical breakthroughs and more about clearer understanding. What once might have been lumped together with other birthmarks is now recognized as part of the normal range of newborn skin findings. Knowing this history can make the early symptoms of stork bite feel less alarming: for many families, it is simply one of those newborn features that becomes less noticeable with time, while for others it remains a faint, harmless mark that does not affect health.
